Abstract
The present invention is directed to a proximal anchoring tab for a side delivered prosthetic mitral valve having an elongated distal tab, where the proximal tab anchors the proximal side of the prosthetic valve using a tab or loop deployed to the A3-P3 (proximal) commissure area of the mitral valve, and wherein the elongated distal tab is extended around the posterior P1-P2 leaflet and/or chordae using a guide wire to capture native mitral leaflet and/or chordae tissue and where withdrawing the guide wire contracts the tab and pins the native posterior tissue against the subannular posterior-side sidewall of the prosthetic valve.
