On Being a Pediatric Cardiac Surgeon

Sunday, November 12, 2006

Introduction

This essay is the product of a request, and represents no small creative struggle on my part—the struggle being what will I write that may be useful, meaningful and provide insight to others about my professional life.  The stated purpose of the request  is to provide the reader, presumably students (college, or perhaps medical school or maybe even high school) a glimpse into the world of pediatric cardiac surgery with the goal of convincing more individuals to pursue a career path in surgery.  The obvious reason for this is that surgery in general, and subspecialty surgery (cardiothoracic surgery) in particular, has become less and less attractive to our “best and brightest”.  FACT:  Applications for residency positions in cardiothoracic surgery have declined significantly over the last decade.  The decline in the number of applicants is of concern to all of us in medicine, irrespective of specialty.  It portends a future of insufficient numbers of qualified practitioners in an environment of increasing medical/societal needs and expectations.  I am grateful to have some opportunity to potentially influence this trend in a positive manner.

I am also grateful for the chance at what is, I hope, the mid-stage of my professional life, to conduct some self-analysis—probably a healthy thing for any professional to do periodically.  Have I made a good career choice, and is my field one I feel good about recommending to others? 

First, a brief description of what I do may be helpful.  I am Director of Pediatric/Congenital Heart Surgery at Texas Children’s Hospital, a large, well-supported, fully integrated children’s hospital.  I perform cardiac and thoracic surgery predominantly in children, although I have an increasingly large number of adult patients with congenital cardiac disease.  This later observation is the result of the ever-growing population of adults with congenital heart disease.  The majority of my patients have congenital cardiac malformations, meaning they were born with something structurally abnormal, “seriously wrong” with their hearts.  As such, the largest percentage of my patients are babies, often premature, requiring early cardiac surgery, because of the lethal potential of their congenital problems.  I also perform heart and lung transplants and place mechanical circulatory assist devices in children with failing hearts.  I work with three surgical colleagues in congenital heart surgery, all highly talented, well educated, and entirely committed.  We work closely with a team of pediatric anesthesiologists; highly specialized anesthesiologists, whom I consider among the best in the world.  Our medical counterparts in Pediatric Cardiology make diagnoses, manage patients before and after surgery, and perform interventional catheterization procedures when appropriate as an alternative to operative procedures.  We all work with a wonderful team of perfusionists, nurses, respiratory and physical therapists, social workers and administrative personnel in an integrated children’s heart center.  It is an exciting, energized, friendly place to work, and I look forward to each day with the expectation of challenge ahead, gratification, and the mutual support of our team.

The course of study to become a pediatric cardiac surgeon varies somewhat; mine was probably longer than most.  After medical school at the University of Texas Medical Branch, I completed residency training (better termed: postgraduate education) in general and cardiothoracic surgery at the Johns Hopkins Hospital in Baltimore, Maryland.   This nine-year program included two years of laboratory research in cardiopulmonary transplantation.  It was a long residency, not always pleasant, but without a doubt it formed the foundation of my professional life.  My wife and I also managed to have our four children during this residency period.  The highlight of my education in pediatric cardiac surgery was a fellowship at the Royal Children’s Hospital in Melbourne, Australia.  My first “real job”, as my mother likes to remind me, came at the tender age of 35 at the Cleveland Clinic Foundation in Cleveland, Ohio.  In truth, I still had much to learn and was, in very many ways, still the student of an outstanding mentor, Dr. Roger B.B. Mee for the next two years.  I was fortunate to be invited to move to Texas Children’s Hospital in 1995.

Admittedly, this whole process has included significant downside challenges.  I do not ever recall making personal “quality of life” decisions in my professional career pathway—it should be clear that there are sacrifices in any career choice, and pediatric cardiac surgery requires significant sacrifice.  Each individual must decide those compromises he or she can tolerate.  Obviously, my education was extremely long—this was financially, emotionally, and intellectually challenging—at times highly stressful.  My family life was, and continues to be, compromised by the demands of my professional life.  That translates into missed birthday parties, school plays, little league games and anniversaries.  I am blessed by a wonderfully supportive wife who has endured the whole process from the beginning.  I have marvelous children.  I believe we have made up for “quantity” with “quality” time, but no doubt there have been disappointments for all of us.  The day-to-day strain of my practice has been different than I expected, and it is still evolving.  It has been physically more difficult than I anticipated—the operations are long and require consistent concentration.  The work is often exhausting.

So why pursue this specialty? 

1. I have the opportunity to perform a large number of very different operations—“mundane” is not a part of our world of congenital heart surgery.  The operations are challenging and are associated with the necessity of improvising and innovation.  When a complex operation is complete, the result is akin to what I envision an artist or builder must feel after creating something useful out of something that was a real problem—a sense of accomplishment.

2. The gratification is tangible and virtually immediate—I can see the results quickly in a child after surgery.  If they were cyanotic (blue from low oxygen levels), their lips turn pink.  If they were in heart failure, they now have energy.  Poor growth (“failure to thrive”) turns around rapidly and children put “meat on their bones”.  Children heal quickly.  They respond positively to well-performed operations.  They are not burdened by preconceived notions about recovery as adults often are—they just want to feel better, to be like other children.

3. The impact of operations that I perform on newborns has the potential to affect/influence an entire normal lifespan.  Thus, the results of my work have implications and the potential to be realized over decades, not just months or even years.  One example is the case of obstructed, total anomalous pulmonary venous return.  This is a fatal condition in which the pulmonary venous drainage (oxygenated blood) returns abnormally, and the pathway to the heart is narrowed or blocked.  These babies often present moribund very soon after birth, with death imminent within hours without treatment.  A successful operation with precise repair will likely be translated into rapid recovery and the potential for lifelong normal cardiac function.  This procedure is extremely rewarding.

4. The patients are very interesting, and the physiology is fascinating.  We treat patients with too little pulmonary blood flow or intracardiac mixing, and they have low systemic oxygenation—“blueness” or cyanosis.  We treat patients with excessive pulmonary blood flow (overcirculation of the lungs). They have enlarged hearts, congested lungs and respiratory distress—congestive heart failure.  We treat obstructed valves, incompetent valves, narrowed arteries, absent connections, and twisted pathways.  We have patients with situs abnormalities—“backward hearts”.  We have patients with absence or hypoplasia (underdevelopment) of cardiac chambers—single ventricles.  This translates into a wide variety of anatomic and physiologic issues to be unraveled and corrected. 

5. I use very specialized equipment, which just keeps getting better; advancements in technology are important to what I do.  My “tools” are highly refined, very delicate instruments—critical to optimum performance.  I use a cardiopulmonary bypass “heart/lung” machine routinely to support the circulation during open-heart repairs.  We monitor the brain with near infrared spectroscopy (NIRS) to determine adequate oxygen delivery.  We study echocardiograms, cardiac catheterizations, MRIs, and CT scans to understand anatomy and function.  We make neonatal diagnoses and surgical plans—even in some cases considering fetal intervention.  We have an ever-growing number of mechanical devices available to support the child’s circulation long-term when the heart fails [Figures 1 & 2].  We are able to replace the failing heart and lungs with transplants when appropriate.  It makes for a very exciting life; seldom predictable, often frightening, never boring.

6. I go to work every day with some of the most dedicated and accomplished people in the world.  My associates are smart, ethical, focused, and committed.  There is a spirit of community and mutual appreciation of the highest standards of patient care.  We earn comfortable livings, but we are not driven to measure our performance by income levels.  I am constantly challenged and uplifted by the professional standards of my associates.  The spirit of service is tangible and infectious; my professional life is buoyed by my colleagues.  In an increasingly cynical world of corporate scandal, disappointing behavior by our elected officials, and conflicting societal messages, our sense of mission and purpose remains clear.  We take each day as an opportunity to do what is best for the children entrusted to our care.

In conclusion, I find pediatric cardiac surgery to be challenging, exciting, varied, and extremely rewarding.  I have no regrets about the path my professional life has taken, and I would encourage others to pursue a similar career choice.  It continues to be a very enjoyable professional life.
