Pseudoaneurysms of the left ventricle are rare complications after acute my
ocardial infarction. We report on a 69 year old patient with a large false
aneurysm located in the posterolateral ventricular wall. It became clinical
ly apparent during an episode of severe left heart failure. Echocardiograph
y and left ventriculography allowed an accurate determination of localizati
on and dimension of the pseudoaneurysm; coronary angiography revealed a pro
ximal occlusion of the left circumflex coronary artery. Because of the high
risk of rupture, a rapid surgical repair of the false aneurysm was indicat
ed.
