Abstract
Abstract A ventricular patch to restore the ventricular architecture of the heart includes a sheet of biocompatible material having a generally oval configuration, and a continuous ring fixed to the sheet. The ring has a generally oval configuration similar to the generally oval configuration of the sheet of biocompatible material. The ring defines a central generally oval region of the patch inside the ring and a circumferential region of the patch outside of the ring. The central generally oval region has a major axis and a minor axis. The ratio of the major axis to the minor axis is about 4:1.
