Why Cardiac Surgery and Cardiology Are Merging

Cardiac surgery and interventional cardiology are two rapidly progressing fields that are now converging. Dr. Tsuyoshi Kaneko, MD, explains that this represents a return to a more unified approach to medicine. Historically, general surgery encompassed a vast range of procedures. Over time, these disciplines dispersed into highly specialized silos like cardiac surgery and interventional cardiology.

The advent of transcatheter devices has been the primary driver behind this renewed merger. These innovative technologies allow physicians to operate on high-risk patients through minimally invasive techniques. As Dr. Tsuyoshi Kaneko, MD, notes, the line between a "minimally invasive cardiac surgery" and a "maximally invasive interventional cardiology procedure" has become beautifully blurred.

The Vision of Dr. Michael J. Davidson, MD

The late Dr. Michael J. Davidson, MD, was a pioneering advocate for cross-training between these two specialties. His vision was forward-thinking and patient-centered. He recognized that the future of cardiovascular care would require a new kind of heart specialist.

Dr. Davidson championed the idea that a modern cardiac surgeon must also possess skills in interventional cardiology. This philosophy was not just about learning new procedures. It was about creating a holistic understanding of heart disease treatment from multiple angles. Dr. Tsuyoshi Kaneko, MD, followed in these footsteps, spending time in the catheterization lab after his formal surgery training to fully embrace this dual perspective.

Benefits of Cross-Training Beyond Technical Skill

While obtaining technical ability in both open-heart surgery and cardiac catheterization is important, Dr. Tsuyoshi Kaneko, MD, argues that the greater value lies elsewhere. The primary benefit of cross-training is gaining the vision of both specialties. A physician who can think like a surgeon and a cardiologist can understand the entire treatment pathway for a patient.

This dual perspective enables a physician to anticipate what's coming next in heart treatment innovation. It fosters an "outside-the-box" vision that is crucial for advancing the field. Many trainees focus intensely on the technical aspects, but Dr. Tsuyoshi Kaneko, MD, emphasizes that sharing the core philosophies of different medical specialties is the key to true innovation.

The Power of a Multidisciplinary Heart Team

This convergence directly benefits patients through a multidisciplinary team approach. Instead of being siloed into a single specialty's pathway, patients are evaluated by a unified heart team. This team combines the expertise of cardiac surgeons and interventional cardiologists.

Dr. Anton Titov, MD, and Dr. Kaneko agree that breaking down these traditional silos leads to better patient outcomes. The merged "heart treatment silo" ensures that treatment decisions are based on what is best for the patient, not on which department they enter first. This collaborative model is now considered the gold standard for complex cardiac care.

The Future of Heart Treatment and Innovation

The merger of cardiac surgery and interventional cardiology is shaping the future of heart treatment. The development of new transcatheter devices for valves and other structural heart problems is a direct result of this collaborative environment. This trend necessitates a fundamental change in how future physicians are trained.

Formal training programs themselves will need to merge to produce the next generation of heart specialists. These hybrid physicians will be inherently innovative because they can see solutions that are invisible to those trained in only one discipline. They are the key to developing the next breakthrough technologies in cardiovascular medicine.

The Dr. Michael J. Davidson Fellowship for Cardiac Innovation

To honor this vision and foster this new generation of innovators, the Dr. Michael J. Davidson Fellowship for Cardiac Innovation was established. As Dr. Tsuyoshi Kaneko, MD, describes, the fellowship's purpose is to encourage "thinking outside the box." It serves as a living memorial to Dr. Davidson's groundbreaking ideas about cross-disciplinary training.

The fellowship is designed to support physicians who wish to bridge the gap between specialties. It provides them with the resources and environment to develop the dual vision that Dr. Davidson and Dr. Kaneko champion. This ensures his legacy continues to drive progress in heart treatment for years to come, ultimately benefiting countless patients worldwide.

Full Transcript

Dr. Anton Titov, MD: You worked with Dr. Michael J. Davidson, MD. He was a strong proponent of cross-training in endovascular cardiology and in cardiac surgery.

Dr. Anton Titov, MD: You recently wrote a very poignant introduction to the Dr. Michael J. Davidson Traveling Fellowship for Cardiac Innovation. You called it "Thinking Outside the Box".

Dr. Anton Titov, MD: What is the idea behind cross-training in both endovascular cardiology and cardiac surgery?

Dr. Tsuyoshi Kaneko, MD: Correct. It's a very important question because endovascular cardiology and cardiac surgery areas are progressing. They are merging again.

Previously, general surgery used to cover everything. They used to cover general surgery, surgery in the abdomen, breast surgery, endocrine surgery, heart surgery, and lung surgery. But not only that. General surgery involved urology, neurosurgery, ENT, and orthopedics. Everything used to be included in surgery, but it really dispersed out into each individual specialty.

As the surgery subspecialties are really progressing, we are seeing a convergence of these specialties again. For instance, in our field, cardiac surgery, these new devices—the transcatheter devices—really have merged the specialties of cardiac surgery and interventional cardiology.

We operate on high-risk patients with these transcatheter devices. I don't know if we are doing a minimally invasive cardiac surgery or a maximally invasive interventional cardiology procedure. Endovascular cardiology and cardiac surgery are merging into the same field.

That really brings the merging of the field. It also really necessitates the merging of the training programs. We are going to merge endovascular cardiology and cardiac surgery. Then we need a surgeon who's trained in cardiac surgery, but such a cardiac surgeon must also have skill in interventional cardiology.

That was the vision of Dr. Michael J. Davidson. I followed in his footsteps. I spent some time in the catheterization lab after I finished my formal cardiac surgery training. Therefore, I was able to see both specialties.

It is very important to get a technical ability in both specialties. You get to do open-heart surgery, and you get to do a cardiac catheterization. But the more important thing, I think, is to understand the vision of both specialties.

I can think from a cardiac surgery standpoint; I can also look from a cardiology standpoint. I can understand what's coming next. I think that is what really will create an outside-the-box vision for heart treatment. I think that is the key factor.

A lot of physicians focus more on the technical aspect of learning how to do cardiac catheterization. Surgeons focus on learning how to do heart surgery. I think the technical aspects are more of the focus of the trainees.

For me, the more important thing is to share the visions of other medical specialties. You can look into something new that will be upcoming in the future.

Dr. Anton Titov, MD: I think that is the whole purpose of us establishing this new fellowship in memory of Dr. Michael J. Davidson, MD. I think this is also important: how patients could be evaluated by a multidisciplinary approach instead of being siloed through the particular specialty of medicine or surgery.

Dr. Tsuyoshi Kaneko, MD: Absolutely, yes! I think that the silos of cardiac surgery and interventional cardiology are merging. It used to be two different specialties, and now it's merging into one big heart treatment silo.
