Operative removal of a slice of normal, non-scarred left ventricular muscle is called partial ventriculectomy. The operation was developed by Dr. Randas J. Batista in Brazil. The goal is to improve the function of a dilated left ventricle by reducing the chamber dimensions and remodeling the spherical ventricle to a more efficient cylindrical shape. It is hoped that this operation may provide an alternative to cardiac transplantation.

Postoperative transesophageal image showing the resulting decrease in left ventricular internal dimensions.
