Apparatus and methods to reduce ventricular volume are disclosed. The device takes the form of a transventricular anchor, which presses a portion of the ventricular wall inward, thereby reducing the available volume of the ventricle. The anchor is deployed using a curved introducer that may be inserted into one ventricle, through the septum and into the opposite ventricle. Barbs or protrusions along the anchor body combined with a mechanical stop and a sealing member hold the device in place once deployed.
