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 that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prostheticheart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.

The disclosure of the earlier application is considered a part of the disclosure of the present application and is 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 planned to treat the mitral valve, a majo...
