Optimizing Ventricular Shape in Anterior Restoration

Abstract

Ishemic dilated cardiomyopathy results from altered muscle mechanics. Ventricular restoration is aimed at altering the volume and shape changes that follow myocardial infarction. Optimal surgical methods to achieve this goal are not well defined, but it has been shown that sphericity is an important determinant of long-term outcome. We present the rationale and techniques for returning the globular remodeled ventricle to a more elliptical shape. Clinical data from our RESTORE registry does not suggest an improvement in early or late mortality with such methods but opens the way for late evaluation of functional and exercise capacity.
