Episode 37: Dr. Allan Stewart’s Childhood Appreciation of Mechanics Lead to “Unroofing” of Myocardial Bridges.

September 10, 2024

What if the future of heart surgery didn’t involve massive scars and long recovery times? On this episode we’ll visit the pioneering world of minimally invasive cardiac procedures through the eyes of Dr. Allan Stewart, Medical Director and Chief of Cardiovascular Surgery at HCA Florida Mercy Hospital. A leading cardiac surgeon, his journey from childhood started with an understanding of mechanics that led to groundbreaking medical innovations. His path is nothing short of inspiring. Dr. Stewart shares the pivotal moments that led him to transform the field, including a captivating Nova episode on pediatric heart transplants, and his many years of practice using minimally invasive techniques.


Ever wondered how surgeons tackle the complexities of myocardial bridges? Dr. Stewart takes us on a compelling journey through his unexpected dive into this challenging area while at Columbia University. He explains the intricacies of diagnosing and treating these conditions, and the critical decision-making involved in whether to perform surgeries on a beating heart or with a pump. From ensuring precision to avoid catastrophic complications like cutting the artery, to the difficulty of accurate diagnosis, this segment shines a light on both the art and science of cardiac surgery.


Finally, we’ll delve into the crucial importance of thorough and precise surgical intervention. Incomplete arterial surgeries can lead to devastating consequences, including the need for complex redo surgeries. Dr. Stewart emphasizes the necessity of proper techniques to prevent complications and stresses the importance of educating both patients and cardiologists about the risks associated with myocardial bridges and inappropriate stent use. Join us for this enlightening conversation, and on a lighter note, I look forward to a future bike ride together in South Florida. Don’t miss this episode with one of the field’s most innovative minds.
