Pulmonary Arterious Malformation as Rare Cause of ST-Segment Elevation Myocardial Infarction.

ABSTRACT:

Background

Pulmonary arteriovenous malformation (PAVM) is a rare shunt between the arteries and veins of the lungs, which can lead to paradoxical embolism. It is mostly caused by an autosomal-dominant disorder called hereditary hemorrhagic telangiectasia.

Case summary

A 62-year-old woman presented with acute chest pain, initially diagnosed as ST-segment elevation myocardial infarction. Further investigation revealed myocardial infarction with nonobstructive coronary arteries (MINOCA) caused by a PAVM. It was successfully embolized with an Amplatzer device.

Discussion

Multimodality imaging is the cornerstone of the differential diagnosis of MINOCA, a conglomerate of rare causes of myocardial infarction. In our case, we identified PAVM as the cause of myocardial infarct
