Ventricular Septal Aneurysms

Abstract
Two cases of ventricular septal aneurysm are reported, one in the membranous septum and one in the muscular portion. The diagnosis was made by selective left ventricular angiography. It is suggested that these cases represent spontaneous closure of a ventricular septal defect with weakness and aneurysmal formation due to the high left ventricular pressure. Both are asymptomatic and hemodynamically within normal limits. Surgical repair of the aneurysms is not considered necessary.
