Asymmetric Pulmonary Perfusion Causing Unilateral Pulmonary Edema As a Complication of Acute Myocardial Infarction

Acute unilateral pulmonary edema is an unusual clinical condition occasionally associated with severe mitral valve insufficiency. We describe a patient diagnosed as having unilateral pulmonary edema after an acute anterior my- ocardial infarction. Echocardiograms performed in the acute phase ruled out mitral insufficiency. A perfusion lung scan showed left-sided pulmonary hypoperfusion. The diagnosis of acquired hypoplasia of the left pul- monary artery tree was made by chest computed tomog- raphy. The pathogenesis and differential diagnosis are discussed.
