Systems and methods for heart valve therapy

Abstract

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.

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Serial No. 62 / 135,276, filed March 19, 2015. The disclosure of the earlier application is considered part of (and incorporated by reference into) the disclosure of the present application. technical field [0003] This document relates to prosthetic heart valves, such as prosthetic mitral valves, which may be implanted using transcatheter techniques. Background technique [0004] The long-term clinical effects of valvular regurgitation are considered an important cause of cardiovascular-related morbidity and mortality. Thus, for many therapies aimed at treating the mitral valve, a major goal is to significantly reduce or eliminate regurgitation. By eliminating regurgitation at the mitral valve, the damaging effects of volume overload on the left ventricle can be attenuated. Volume overload in mitral regurgitation (MR) involves excess kinetic energy re...

Problems solved by technology

If the anterior leaflet is pulled too far into the LVOT, there is a risk that it interferes significantly with the outflow, creating significant clinical problems
