Summary
Managing degenerated transcatheter aortic valve replacement (TAVR) requires careful planning. A novel technique of selective metal cell excision during explantation preserved coronary access, offering a viable option for high-risk patients.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Prosthetic Valve Disease
Background:
- Coronary access after transcatheter aortic valve replacement (TAVR) is a significant challenge for re-interventions.
- Structural valve degeneration necessitates complex management strategies, with valve-in-valve (ViV) TAVR and surgical explantation having distinct risks and benefits.
