Cardiac Implantable Electronic Device Placement in the Era of Transcatheter Tricuspid Replacement: Approaches and Challenges.

Transcatheter tricuspid valve (TV) interventions (TTVIs), which include transcatheter TV replacement (TTVR) and transcatheter tricuspid edge-to-edge repair (T-TEER), represent a natural evolution in percutaneous valve therapy. However, TTVIs face distinct challenges, chief among them being the frequent presence of transvenous cardiac implantable electronic device (CIED) leads crossing the TV. This review investigates contemporary CIED strategies that eliminate the need for transvenous leads crossing the TV, thereby facilitating safer and more durable integration of device therapy with emerging TTVI technologies.
