A case of false aneurysm of the right ventricle.

False aneurysms of the right ventricle are rare and potentially fatal. A patient is described in whom a trilocular false aneurysm arose from the antero-inferior border of the right ventricle and entered the left hemi-diaphragm. It was successfully treated by closure of the communication with the right ventricle and relief of pulmonary stenosis with right ventricular outflow tract reconstruction. The fifteen previously reported cases of false aneurysms of the right ventricle are reviewed.
