We present a case of a 34-year-old male with dilated cardiomyopathy in whom we performed a new surgical procedure; i.e., ventricular volume reduction to improve function. This initial human experience was preceded by a series of ten sheep in which we demonstrated that by enlarging the left ventricle (LV), the ejection fraction was reduced, and by restoring normal diameter, the LV function returned to normal.
Batista et al. (Fri,) studied this question.
