Interventional Cardiology Insights: A Journey with Innovations
What do the very first TAVRs, rotational atherectomies, and angioplasty studies have in common? Dr. William O’Neill, an esteemed interventional cardiologist whose collaboration and innovation have shaped the field of interventional cardiology. In this episode of BackTable Cardiology, host Dr. Babar Basir welcomes his mentor Dr. William O’Neill. Together, they trace the evolution of interventional cardiology through personal stories, groundbreaking research, and the lasting impact of mentorship and teamwork on the specialty’s past, present, and future.

More about this episode
Dr. O’Neill details the evolution from bedrest-era MI care to intracoronary streptokinase and the advent of reperfusion, his early exposure to balloon angioplasty, and the pivotal studies that proved primary PCI’s superiority over thrombolytics amidst controversy. He explores how physician–engineer collaboration enabled innovations such as aortic valvuloplasty and early US TAVR, including the procedural challenges and regulatory hurdles faced. The episode also covers Dr. O’Neill’s mentorship philosophy, his optimism for the future of cardiology, including breakthroughs in cardiomyogenesis, xenotransplantation, and denervation therapies and his plan to remain up-to-date in the cardiology scene while beginning research on past presidents’ heart disease.
