Mitral valve-in-valve: high-left ventricular outflow tract obstruction risk

Facilitator: T. Kaneko

Speakers: S. Narasimhan, D. Zemanek, A. Alenezi, D. Davidson, M. A. S. Rahmathullah

Summary

This session focuses on the management of high-risk left ventricular outflow tract (LVOT) obstruction in mitral valve-in-valve procedures. It discusses innovative approaches such as the tip-to-base LAMPOON procedure to mitigate obstruction risk, techniques for cutting obstructive tissue, and combined strategies involving sentinel-protected submitral aneurysm closure and transcatheter mitral valve replacement (TMVR). The session further explores TMVR challenges in bioprosthetic valves with unfavorable orientations towards the LVOT, offering critical insights for optimizing procedural safety and efficacy.
