title: Massive coronary arterial aneurysm.
abstract: The pathologic and echocardiographic findings of a massive right coronary arterial aneurysm in a 62 year old man are presented. The thrombosed aneurysm simulated a cardiac tumor, destroying one pulmonary valve cusp. It also caused marked pulmonary stenosis with elongation and narrowing of the outflow tract of the right ventricle and fixation of half of one cusp of the tricuspid valve.
