The number of patients requiring reintervention following transcatheter aortic valve replacement (TAVR) continues to rise as the initial wave of TAVR implants matures. While TAV-in-TAV approaches have shown promise, optimizing outcomes in varying failure modes—such as short-in-tall or short-in-short valve configurations—remains challenging. Clinicians face practice variability in selection strategies, device sizing, imaging interpretation, and procedural safety. There is a critical educational need to review new data, real-world case lessons, and procedural nuances that guide successful reinterventions.
