Implantable Cardioverter Defibrillator (ICD)

By Amin H. Karim MD

Prof. Michel Mirowski, Chief of Cardiology at the Sinai Hospital of Baltimore, Maryland, Inventor of ICD, with Amin H. Karim (Resident in Department of Internal Medicine 1981)

The development of the ICD was pioneered at Sinai Hospital in Baltimore by a team including Michel Mirowski, Morton Mower, Alois Langer, William Staewen, and Joseph “Jack” Lattuca. Mirowski teamed up with Mower and Staewen and together they commenced their research in 1969 but it was 11 years before they treated their first patient.

I was a resident at the Sinai-Hopkins program in 1981-83. We followed the development of the ICD with interest and watched Dr. Mirowski conduct his experiments on dogs. The dog would be attached to electrodes, with a large contraption on a crash cart following the dog. The dog would be put into ventricular tachycardia by stimulation and would collapse to be followed by a auto shock and the dog would be revived! The size of the contraption was the size of a large television; Engineers with Boston Scientic and other companies then worked on it and made it compact and implantable. 

The work was commenced against much skepticism even by leading experts in the field of arrhythmias and sudden death. There was doubt that their ideas would ever become a clinical reality. In 1972 Bernard Lown, the inventor of the external defibrillator, and Paul Axelrod stated in the journal Circulation – “The very rare patient who has frequent bouts of ventricular fibrillation is best treated in a coronary care unit and is better served by an effective anti-arrhythmic program or surgical correction of inadequate coronary blood flow or ventricular malfunction. In fact, the implanted defibrillator system represents an imperfect solution in search of a plausible and practical application.”

The problems to be overcome were the design of a system which would allow detection of ventricular fibrillation or ventricular tachycardia. Despite the lack of financial backing and grants, they persisted and the first device was implanted in February 1980 at Johns Hopkins Hospital by Dr. Levi Watkins Jr.

The first devices required the chest to be cut open and a mesh electrode sewn onto the heart; the pulse generator was placed in the abdomen.

ICDs constantly monitor the rate and rhythm of the heart and can deliver therapies, by way of an electrical shock, when the heart rate exceeds a preset number. More modern devices have software designed to attempt a discrimination between ventricular fibrillation and ventricular tachycardia (VT), and may try to pace the heart faster than its intrinsic rate in the case of VT, to try to break the tachycardia before it progresses to ventricular fibrillation. This is known as overdrive pacing, or anti-tachycardia pacing (ATP). ATP is only effective if the underlying rhythm is ventricular tachycardia, and is never effective if the rhythm is ventricular fibrillation.

Many modern ICDs use a combination of various methods to determine if a fast rhythm is normal, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation.

Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles) and compares it to the rate in the upper chambers of the heart (the atria). If the rate in the atria is faster than or equal to the rate in the ventricles, then the rhythm is most likely not ventricular in origin, and is usually more benign. If this is the case, the ICD does not provide any therapy, or withholds it for a programmable length of time.

Rhythm discrimination will see how regular a ventricular tachycardia is. Generally, ventricular tachycardia is regular. If the rhythm is irregular, it is usually due to conduction of an irregular rhythm that originates in the atria, such as atrial fibrillation. In the picture, an example of torsades de pointes can be seen; this represents a form of irregular ventricular tachycardia. In this case, the ICD will rely on rate, not regularity, to make the correct diagnosis.

Morphology discrimination checks the morphology of every ventricular beat and compares it to what the ICD knows is the morphology of normally conducted ventricular impulse for the patient. This normal ventricular impulse is often an average of a multiple of normal beats of the patient acquired in the recent past and known as a template.

The integration of these various parameters is very complex, and clinically, the occurrence of inappropriate therapy is still occasionally seen and a challenge for future software advancements.

Torsades de Pointes converted by ICD

A number of clinical trials have demonstrated the superiority of the ICD over AAD (antiarrhythmic drugs) in the prevention of death from malignant arrhythmias. The SCD-HeFT trial (published in 2005)showed a significant all-cause mortality benefit for patients with ICD. Congestive heart failure patients that were implanted with an ICD had an all-cause death risk 23% lower than placebo and an absolute decrease in mortality of 7.2 percentage points after five years in the overall population.1 Reporting in 1999, the Antiarrhythmics Versus Implantable Defibrillators (AVID) trial consisted of 1,016 patients, and deaths in those treated with AAD were more frequent (n = 122) compared with deaths in the ICD groups (n = 80, p < 0.001) In 2002 the MADITII trial showed benefit of ICD treatment in patients after myocardial infarction with reduced left ventricular function (EF<30). (Copied from Wikipedia)

Del Oro Hospital Days

By Amin H. Karim MD

In the 1990s, there was a small 100 bed hospital called Medical Center Del Oro Hospital situated on Greenbriar Drive, behind where the Women’s Hospital of Texas is now. it was founded in 1970s by a group of 20 or so physicians and surgeons in the Texas Medical Center who were all affiliated as Non-Baylor Non UT physicians with the major hospitals like Hermann, Methodist and St. Luke’s Episcopal Hospital. They wanted a hospital of their own free of politics as existed in the medical center hospitals with full time faculty and private physicians. (Seems they were ahead of their time). 
The hospital thrived and even added open heart surgery program when a fellow graduating from Dr. Michael E. DeBakey program at Baylor College of Medicine, Dr. Pedro Rubio went into practice and started a open heart surgery program at Del Oro. A couple of cardiologists like Dr. Mehdi Al Bassam and Matheethra Jacob later joined and did interventions in the cath lab with Dr. Rubio providing surgical backup which was mandatory in the early days of plain baloon angioplasty, some ending up with intimal dissections and needing urgent coronary bypass. Dr. DeBakey, as expected, did not like Pedro starting his own program at a neighboring hospital and potentially competing with him. But this is a free country, thank God, and there is little he could do about it. If Pedro was his resident he could have been solidly expelled from the program on the spot! Regardless, Pedro would often tell his encounters with Dr. DeBakey including one where Dr. DeBakey challenged him to car race on Fannin Street and they both did; Pedro, being smart, let the Professor win lest he was fired from the program! I did refer patients to Dr. Rubio and we got along quite well. Since I was one of the early trained fellows in Interventional Cardiology, would assist other cardiologists and teach them a thing or two of balloon angioplasty. 
I would refer some patients to Dr. Rubio but would refer the higher risk patients to Dr. Gerald Lawrie or late Dr. Jimmy Howell at the Methodist Hospital. Patients who came to me from India or Pakistan would prefer St. Luke’s Hospital, one due to Dr. Denton Cooley’s fame and second St. Luke’s offered a “package deal” for coronary bypass whereas Methodist would charge more (often much more). Hermann has it’s own international program too.

Del Oro was sold by the physician owner to HCA Hospital in the early 1980s. HCA was later acquired in the early 1990s by Columbia Hospital System. Later Columbia went bankrupt due to Federal action against them. (will write about that later). It was re-acquired by HCA. In mid 1990s it was shut down and demolished, the land being taken over by the Women’s Hospital of Texas for their expansion.

The photo above was at one of the Holiday parties in the 1990s with late Mr. Denzil Hamblin on the left and Pedro Rubio in the middle. Denzil was very experienced cath lab director and passed away in the early 2000s. Dr. Rubio met with a freak accident at home when he stumbled over the large box TV which a repairman had left inside his house near the front door. He broke his elbow joint and even underwent replacement but unfortunately could not longer operate. He had also pioneered laparoscopic cholecystectomy and wrote a book on it. He was honored by Royalty in Europe which he proudly displayed in his office and on his letter heads. He passed away a decade ago. 

May both rest in Peace.

Private Practice Journey: Part IV Marketing B

This is continuing of the Journey in Private Practice starting from July 1987 and onwards. Marketing efforts for a specialist (non primary care) solo practitioner whose only source of patients is either patient referral, word of mouth, social media, or some other colleagues in primary care, is a ongoing process that has to go on as long as the practice has to continue. This is especially try in a competitive area. Here are some other ways which AngioCardiac Care of Texas employed to remain in focus.

WRITING IN LAY PRESS:
This is not difficult to do. Any public health topic can be addressed to help other people understand diseases and procedures available and prevention measures to be taken. It’s a noble thing to do, in any case regardless.

GIVING TALKS TO HOSPITAL MEDICAL STAFF:
One gentle way of marketing effectively involved giving a Cardiology talk to hospital medical staff or primary care physicians, whenever an opportunity came forward. Topics would include Risk Factors, Screening for Heart Disease, New technology in Cardiology, topics that would interest them. 

Private Practice Journey: Part IV Attack of Vulture Capitalists.

by Amin H. Karim MD

This section will recount in the journey some encounters with entities that representing venture (vulture) capitalists that come to town having done their homework which tells them that there are lot of dollars in the medical world. They also know most doctors are busy in their practices and have little time to look into other sources of income. So if they can be enticed into investing a little capital, sign up to work in the facility and get dividends they can have era income to supplement their practice income. Pretty simple concept and the share of limited partnership would conform to the Federal kick back laws.
I recall some of these (all are in public domain). Some were very successful for all parties concerned and some not so successful, some never got off the ground an some utter failures were the physicians lost everything.

HIGHLY SUCCESSFUL!
The one venture that has always impressed me and still does is the TEXAS ORTHOPEDIC HOSPITAL in Houston. in the early 90’s a large orthopedic group called the Fondren Orthopedic Group partnered with Hospital Corporation of America (HCA) to build a hospital dedicated to Orthopedic Surgery only with related entities like Radiology and Physical Therapy. There were about 20 partners in the group. I am not privy to what the financial arrangement was but word on the street was that the HCA would manage and operate the hospital in return for 20% of income and the rest would go to the Physician Partnership. The surgeons would use the hospital for most of their work. The model proved to be a great success. The hospital added a third floor and parking lot and continues to thrive with 50 plus orthopedic surgeon in one big group.

A second venture that proved very successful was the NORTH CYPRESS HOSPITAL on Highway 290 in Cypress. An entrepreneur made a mid size hospital with processional building and made physician own limited partnership interest in the hospital. The secret to their success was out of network billing which brought them huge profits and dividends to primary care and specialists who were partners and who worked at the hospital. For a while it worked till the savvy insurance carrier realized that patient with out of network benefits were preferentially being treated at the hospital. I think were lawsuits and not sure how they all ended. In any case the hospital was eventually sold to HCA System which now owns and operates the hospital.

Private Practice Journey: Part III Marketing A

by Amin H. Karim MD

If one jumps into a solo practice, one of the first items on the agenda is how to market the practice.
Back in 1980’s here is what I did. Things are bit different now but the samem principles apply:

Making friends with Primary Care Physicians: I made a list of as many primary care physicians in the area as I could find; target was independent physician offices and excluding those connected with the Medical Schools, VA System, County Hospitals etc since they were obligated to refer within the system. When time allowed I would visit each one of them and provided they were not busy with patients meet with them and leave business cards. Remember the 3 words that someone taught me a long time ago: be AVAILABLE, ACCESSIBLE AND AFABLE! Not all PCPs are easy to convince and break away from the usual referral patterns or ” buddy networks” but even a few breaks are welcome and once you start working with them and impress them with your communication and good care, you may get a long term referral source. More convincing is if the patient goes back and says good things about you.

Arranging an talk at a restaurant on a cardiology topic that would interest other physicians. This would take some investment or if one is lucky a drug rep might offer to underwrite the expenses. This is as long as they understand that your talk will be unbiased.

Buying an infomercial on local TV or radio. Luckily I was approached by a Spanish TV station to be interviewed by an anchor and answer questions on cardiac topics. Same with local radio stations. This gets your name out in the community.

Organizing special events: (1990s) Here we learned something from Prof. Denton Cooley. Although, Dr. Cooley was full resident of St. Luke’s Episcopal Hospital, and on faculty at the University of Texas, Houston and founder and Chair of the Texas Heart Institute, but in fact he was a private practitioner just like the rest of us independent cardiologists. He has about 6 partners in his practice and he had an exclusive arrangement with St. Luke’s such that no other CV surgeon could have privilege to do surgeries at the hospital unless they joined his practice. It was rumored that even Dr. Michael Reardon, who was his fellow, got independent surgery privileges at St. Luke’s. As a result, Dr. Reardon ended up going to next door Methodist Hospital ( a big gain for Methodist as Dr. Reardon established a very good practice and continues to be a busy CV surgeon at Methodist.
In any case, Dr. Cooley excelled in marketing his practice. A cardiologist Dr. Virendra Mathur, was his referral and with him Dr. Cooley would visit Bombay, India and meet cardiologists there, ensuring a steady referral from India. As expected, these referrals would be well to do people or VIPs paying cash to St. Luke’s. (which had a good cash pay program for overseas patients). Personalities like Bollywood singer and actor Kishore Kumar and Pakistani nightingale singer late NoorJejan came to St. Luke’s for their CV surgery. So di many industrialists from Pakistan, some of who later became my patients once they found that there was a Pakistani descent cardiologist just next door to St. Luke’s.
Locally, Dr. Cooley would organize a get together of his referral cardiologists every holiday season at his beautiful ranch in Rosenberg, Texas called the Cool Acres Ranch. It had streams running through it and 5 big houses. He would arrange a barbeque and fire works for children. We would have a good picnic at his ranch. It was friendship, camaraderie, marketing and goodwill all rolled into one and showed his talents, outside the operating room. He was a pleasant and friendly person who treated his colleagues with respect. His surgical skills do not need any praise as he was outstanding. In later years, he would not keep up with the advances in CV surgery like mini-cab with smaller incisions and off pump CABG, calling them ” mere gimmicks” ( as he once told me). But his legend, like that of Dr. DeBakey lives on at the Texas Heart Institute Building.

TAKING PART IN HEALTH FAIRS:
One way to spread the word about your practice was to take part in Health Fairs, some organized by the hospital system, some by the local community associations (eg Association of Pakistani-Descent Physicians of North America APPNA South Texas Chapter) or the Islamic Society of North America (ISNA) or the Islamic Council of North America (ICNA) or the Pakistan Association of Greater Houston (PAGH). Photo below is the Health Fair in 1995 at the Women’s Hospital of Texas on Fannin Street.

Private Practice Journey: Part II Navigating Managed Care

By Amin H. Karim MD

PRE MANAGED CARE ERA:
When I started solo cardiology practice in 1987, not much was heard about Managed Care in general. There was MediCare, Medicaid (Federal program for people below poverty line: patients did not have to pay anything to any provider) and then there was INDEMNITY insurance like BC BS and others which paid the provider for whatever health care service was needed on the basis of usual and customary charges. Many physicians, even in those days did not participate in MediCaid and this situation persists even today. However, there already was PruCare which was a plan of the Prudential Insurance Co and there was only one provider group called the Macgregor Clinic which held their contract. I learned for the first time what an HMO ( Health Management Organization) was; MacGregor had a HMPO contract with them meaning they were paid a fixed amount per patient and they managed the patients in that budget. Another name we heard was NYLCARE by the New York Life Insurance. We heard that they denied tests and were nicknamed DENIAL CARE! 🙂

THE ARRIVAL
But the age of Managed Care had arrived. Now we had managed care companies that you had to become a member of to see their patients. That meant more paper work and several page agreements that we rarely read; it had the payment schedule as to how much we would be paid for visits and procedures and they were usually lower than what the INDEMNITY insurance.
Most physicians and groups gladly signed up for them; the attraction for them was that they would be listed on the panel of those companies which would therefore give them popularity and a chance to get referrals from PCPs. Little did they realize that in signing up with them they were agreeing to their pre determined rates and could not collect any difference from the patients other than deductibles and co-pays. They would later learn that once signed up and tied to the patient volume offered by these companies, the rates would keep coming down year after year till they would become close to or even lower what MediCare paid! Now if they resigned they would lose all the volume of patients. The larger group had the wherewithal to negotiate better rates but the small groups and solos simply accepted their fate. This situation persists even today and Managed Care companies now rule the roost, requiring pre-authorizations for every procedure done in the clinic. Soon Medicare Advantage Plans would start taking over traditional Medicare from patients with promises of providing them with dental and eye coverage etc. Little do patient realize that they are giving up their freedom to choose the doctor or hospital. Fast forward from early 2000 to the 2023, these plans have grown too big for their breeches now: See the news report from November 27 2023:

These and other insurance barriers have resulted over the years to increase the practice costs for the solo physician, while salaries and rents have continued to increase steadily in keeping with inflation. One or two people have to be hired to do ” pre-authorizations” for procedures, sometimes denied till the physician does a “peer to peer” review with their designated physician, often not in the same specialty.

INDEPENDENT PRACTICE ORGANIZATIONS:
One entity that came to the rescue of solo and small practices was the start of Physician Practice Organizations, established with the help of hospital systems; joining these provided a mechanism to negotiate payments from HMOs and PPOs as well as not having to filling forms for each company separately at times of renewal.
I joined the following:
Cardiovascular Care Providers
St. Luke’s Independent Practice Association
Methodist IPA.
Gulf Coast IPA
Twelve Oaks IPA
The last three are closed now. The first two have been very helpful in keeping our contracts.


Private Practice Journey: Part I Jumping in the Pool.

By Amin H. Karim MD
JUNE 1987:
The three year Cardiology fellowship at Baylor College of Medicine, Houston, Texas would soon end as of next month. The third year of fellowship ( as will be described in other pages) was a very busy one being on the TIMI I team along with 3 other fellows Dr. Neil Kleiman (now Director of Cath Lab at Houston Methodist Hospital), Dr. Saul Silver, and Dr. Dennis Goodman. All of us were given the third year as Interventional Fellowship on the condition that we would be the foot soldiers of the TIMI I protocol. (more on other pages)

For now the question was how best to start a private practice, having already decided that Academic job was not for me nor joining a another cardiology group. The decision to stay in Houston, Texas was already made by Shahnaz and me. The task now was to plan, budget and get started in practice. Once the Baylor job ended on June 30, 1987 I better have enough to support the family, have health insurance for family of four and other expenses. As Shahnaz was still studying for ECFMG, there was only one bread winner.

Fist step was to assess the financials condition. Luckily, I had managed to moonlight on the weekends during slower rotations. Moonlighting jobs were available in the precursors of today’s Urgent Care Centers. They were walkin clinics open from 7 AM to 11 PM. One such clinic was the MediClinic with 7 branches in Greater Houston and I would choose the one with the least traffic so that I could take my Braunwald’s Cardiology and study for the Cardiology Boards. Fellow’s salary those days was about $25,000 a year; However, cost of living was low too. Our 2 bed room apartment close to the medical center cost $350 a month. With all that there was about $4000-5000 in savings account that could be the initial cash burn in the new practice as well as living expenses.

The next stage in the strategy was to apply to about 5 neighboring hospitals for privileges. All got approved but some provisional to begin with and no procedure privileges till training was officially complete. These hospitals were:
The Houston Methodist Hospital
The St. Luke’s Episcopal Hospital
The Medical Center Del Oro Hospital
The Women’s Hospital
The Park Plaza Hospital

A small 1000 square foot office was located about a mile from the Houston Methodist Hospital on South Main Street in a 5 story building. It was already built out and vacated by another physician. A dermatologist was selling all his used office furniture for $1100; Even bought a used G.E. Ecocardiogram machine from late Dr. William Gaston, a Methodist Cardiologist. I hired a front office girl for $7 an hour. All appointments and payment ledgers were on paper. Later, IMB introduced a nice PC with 20 MB of hard drive which was on sale for a whopping $3500! It came with the DOS operating system; Word or Word Perfect had to be bought separately. A program called RapidFile was used for data base accumulation like addresses and phones. Once the office was set, and come July 1, 1987 I was transformed from a fellow to a consultant or attending physician with my own office! Oh, what a feeling! 🙂
There were other paper formalities like applying for Medicaid, Medicare, Champus, BCBS and as many private insurnace


CALL COVERAGE:
The next step was arranging call coverage which is a requirement for most hospitals and health care systems. I was lucky to have Dr. Mohammed Attar (originally from Syria and Lebanon) who was already in practice and was my attending during fellowship. He too was a solo practitioner and was happy to cross cover. His practice was busy so one advantage was that doing rounds for him on weekends gave me more to bill and occasionally someone would need a emergency procedure.
Dr. Sarma Challa in Methodist Hospital Baytown was very busy and the only cardiologist who actually lived in Baytown. The Chapman group at Methodist Houston ( a 7 member group started by Dr. Don Chapman who was a pioneer of invasive procedures at Houston Methodist) went once a week to Baytown. Baytown did not have coronary surgery program and Dr. Challa would bring all his patients to Houston. I would cover for him during the days he could not make it to Houston ( 30 mile drive along the busy I-10).
Call coverage also promoted networking and establishing relationships with established cardiologists.

But the struggle had just begun. Of all hospitals, the small Del Oro Hospital which was initially established by a group of physicians and surgeons, and later sold to HCA Systems, was the most receptive and helpful, simply because they needed new cardiologists. They had 2 already. I was fully trained in PTCA and one of the cardiologists wanted to do angioplasties but was not trained. I would scrub with him and could bill as an assistant. Later Medicare abolished assistant payments. In any case, I wanted to sharpen my angioplasty skills and would help anyone who needed my help, even at the Methodist Hospital. St. Luke’s was very strict and wanted new fellows to scrub with an established attending for 10 cases (which they would bill) as proctor before the privileges were granted. But privileges at St. Luke’s helped in another way later since Dr. Denton Cooley drew patients from Pakistan and India and some of the well known rich Pakistani industrialists became my patients. Sr. Luks’s also had a good discount rates for cash patients from abroad which Methodist lacked. Dr. Cooley in addition to being a master CV surgeon was also a good businessman and knew well how to market. I remember seeing a St. Luke’s ad in a magazine that you see in the pocket of the seat in front of you in an aircraft!

Once hospital privileges were in place, the next step was how to market oneself for referrals. The bread and butter of a consulting physician of any specialty was referrals from primary care physicians. So one method was to visit them whenever possible with cards and requisition form for test like Echo, stress tests, Holter etc. Referrals from hospital was easier since most surgeons want cardiology clearance and someone to follow on a day to day basis. I got to make friends with many good surgeons and internists. The best way I found to gain the respect of referring docs in the hospitals was to be available and affable. (as one proctor told me). Emergency room doctors were another source of great referrals of unstable angina or acute MI.

The moonlighting of course continued since even when insurances were billed, it took a few months for cheques to start rolling in. I worked at a MacGregor Clinic (now gone) which was a large multispecialty group with PruCare contract (by Prudential Insurance Co). I was paid $25 an hour for supervising treadmill stress tests. I would do 15-20 of them in a 3-4 hours and make reports. Another moonlighting job was at the West Houston Hospital at $20 an hour to take care of Surgical ICU patients and so forth. At least these jobs brought in cash at the end of the month to pay the bills and save some for visit to Pakistan.

Now for furthering the practice, one looked at the map of greater Houston and see where the smaller hospitals were in the periphery with no cardiologist coverage. I found several eg. Alvin Community Hospital (now taken over by Clear Lake Medical Center), The Angleton-Danbury Hospital, (now taken over by UTMB), the Lake Jackson Hospital (also taken over by UTMB), The BayCity Hospital, The Mainland Center Hospital in Texas City; The plan was to visit each of these hospital Emergency Rooms and make friends with the ER docs and let them know you could take acute MI patients. In those days, these hospitals would call Hermann LifeFlight or Methodist Helicopter Service and transfer the acute MI patient with or without first giving TPA. Depending on their condition we could either manage conservatively or take them straight to cath lab for rescue PTCA.

Not that it was easy to cover these distant hospitals. Once you got privileges in these places, you could be called any time of the day or night to see a consult or to read an echo. For example, Mainland Center Hospital was atleast 40 miles away from my home. Sometimes, I would be called to read a study and I would have to drive there. Now, remember we had no mobile phones then and we carried Motorola pagers for nurses to call us. If you got a call while driving on I-45 Freeway, you would have to exit the freeway and find the corner gas station. The area may not be the safest. You carried change in your car to make the phone call. Mercifully, cell phones arrived. I bought a Motorola cell phone the size of a brick which cost $2000. Twenty minutes of talk time per day was $100 per month!

More hospitals were added by me for obtaining privileges including Southeast Memorial Hospital (was not under Hermann yet), the Spring Branch Medical Center (now closed) The Sam Houston Hospital (now closed), The SunBelt Hospital (now closed due to flood destruction), At one time the toral number of hospitals and skilled nursing facilities I had privileges at numbered about 15! You can imagine rounds at these hospitals took time and would last till 11 PM.

The reward, of course, was good. There were no HMOs or PPOs. Medicare paid good for procedures. it took a couple of years ( I had been told it would) to get to a comfort zone of regular office visits, procedures, hospital admissions, consults and other work to get the practice going. Many interesting things were encountered like being approached by a attorney group to take care of a guy involved with a well known case and being a expert witness for him. (more later on that). Attorneys pay well for these cases. Also got in the cross fire of a lawsuit against a urologist when his patient died of bleeding after prostatectomy and I happened to be the cardiologist who had cleared the patient. I was, of course, non suited and later learned that the reason the lawyers get all the docs on the case involved is so they can get free expert witnesses’ when these docs try to defend themselves and inadvertently point fingers at the surgeon! There was much to learn about medico-legal medicine later in practice.

One great satisfaction was that both the Internal Medicine Boards and the Cardiology Boards were cleared in the first attempt. Later in 1999 I cleared the Interventional Cardiology Boards. Mercifully, the first two boards were grand fathered when the rules changed and were valid indefinitely and we would never have to appear in subsequent recertification. The Interventional Board expired in 10 years and I never re took it. Not that anyone cared anyone since no hospital took my interventional privileges away as long as I was actively admitting to the hospital. I still take STEMI calls.
