Systems and Methods for Heart Valve Therapy

摘要

Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. For example, this document describes prosthetic heart valve designs and techniques that reduce or prevent obstructions of the left ventricular outflow tract that may otherwise result from systolic anterior motion of an anterior leaflet of the native mitral valve.

主权项

1. A prosthetic mitral valve system comprising:
a valve assembly comprising an expandable valve frame and an occluder attached to the expandable valve frame; and an anchor assembly comprising an expandable anchor frame, the anchor assembly configured to selectively couple with the valve assembly, the expandable anchor frame comprising a systolic anterior motion (SAM) containment member that is configured to be at least partially disposed behind an anterior leaflet of a native mitral valve when the expandable anchor frame is engaged with the native mitral valve.
