1. A method for reducing left ventricular volume in a congestive heart failure heart, the method comprising the steps of:
- applying suction to an epicardium of said ventricle;
bringing opposing walls of said ventricle together via suction so as to reduce the size of the left ventricle, said opposing walls including a first wall and a second wall; and
penetrating a needle across said first and second walls of said ventricle while said first wall contacts said second wall;
wherein said suction is applied by engaging the epicardium with a suction device so that the epicardium is drawn into the suction device and inner surfaces of said first and second walls are brought together.

Abstract
A method for reducing left ventricular volume, which comprises identifying infarcted tissue during open chest surgery; reducing left ventricle volume while preserving the ventricular apex; and realigning the ventricular apex, such that the realigning step comprises closing the lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle in a dyskinetic ventricle of a heart.
