Abstract
A distal end of a guide catheter is transvascularly advanced into a left ventricle of a heart of a subject. While the distal end of the guide catheter remains disposed in the left ventricle, a first tissue anchor of an implant is deployed from the distal end of the guide catheter. Subsequently, the guide catheter is retracted while progressively exposing the implant. Subsequently, a second tissue anchor of the implant is anchored to a posterior annulus of a mitral valve of the heart by deploying at least part of the second anchor within a left atrium of the heart, such that the implant extends from the first tissue anchor, over an atrial side of a posterior leaflet of the mitral valve, and to the second tissue anchor. Other embodiments are also described.
