The field of transcatheter aortic valve replacement (TAVR) continues to evolve, with new research expanding its indications and refining its application. This JACC special issue brings together cutting-edge studies, meta-analyses, and expert perspectives on key topics shaping the future of TAVR. Highlights include pivotal trials assessing TAVR in low-risk patients, a growing focus on moderate aortic stenosis and heart failure, and novel insights into reintervention strategies. The issue also presents comprehensive analyses on asymptomatic severe aortic stenosis, valve durability, and patient selection for next-generation TAVR applications. As TAVR increasingly moves beyond its initial role in high-risk patients, the studies featured here provide essential data to guide clinical decision-making, optimize outcomes, and address the challenges of valve longevity, structural durability, and patient-centric approaches. We hope this collection informs and inspires continued innovation in structural heart disease management.
