1. A method for reducing left ventricular volume in a congestive heart failure heart, the heart having a left ventricle, the method comprising the steps of:

  • a. identifying infarcted tissue during open chest surgery;

    b. dilating said ventricle by applying suction to an epicardium of said ventricle;

    c. reducing the left ventricle volume by clamping of the dilated portion of said ventricle so as to bring walls of the left ventricle together;

    d. securing the clamped portion by stitching along the clamped portion with the stitching penetrating through the clamped walls to affix the walls of said ventricle together to achieve appropriate functional contractile geometry of said ventricle.
