Abstract

A system is provided for treating valvular disease percutaneously though a ventricular apex of the heart. The system includes a needle for piercing through the ventricular apex of the heart and creating a hole whereby a catheter can be passed through the skin and the wall of the heart to gain access to the interior of the heart. Once percutaneous access to the heart is obtained, any of a variety of techniques can be utilized for annular and/or valvular therapy and/or repair through the catheter. A closure device is necessary for closing the puncture of the heart. Any of a variety of vascular closure devices can be modified to be utilized with the system to close the puncture of the ventricular apex of the heart.
