When, in 1960, the pioneering cardiac surgeon Dr. Dwight Harken performed one of the first successful open-heart procedures using cardiopulmonary bypass, few could have imagined the astonishing trajectory that cardiac surgery would follow in the decades to come. At the time, the very notion of stopping the heart, repairing its inner architecture, and restarting it with precision was a revolutionary step. Who could have foreseen that by 2026, structural heart disease would be approached not only through sternotomy and sutures, but also through catheter-based valve implantation, robot-assisted resections, and hybrid operating rooms where interventional cardiologists and cardiac surgeons collaborate in real time? What once required massive incisions and prolonged recovery is now often performed through mini-thoracotomies, percutaneous routes, or even fully endovascular techniques, delivering life-saving therapy to patients once deemed inoperable. Today, structural cardiac interventions are not just evolving—they are being redefined.
