Evolution of a Pseudoaneurysm Due to Microvascular Obstruction in Myocardial Infarction Assessed by Cardiac Magnetic Resonance.

ABSTRACT:

Background

Ventricular pseudoaneurysm (PsA) is a rare but serious complication after acute myocardial infarction (MI) that can lead to heart failure, arrhythmias, thromboembolism, and death.

Case summary

A PsA was diagnosed in a patient with an unrevascularized inferolateral MI. Cardiovascular magnetic resonance showed late gadolinium enhancement and microvascular obstruction, followed several weeks later by wall rupture and PsA formation.

Discussion

A left ventricular PsA should be differentiated from a true aneurysm and other post-MI complications such as ventricular septal defect and Dressler syndrome. While transthoracic echocardiography is often sufficient for diagnosis, challenging cases may necessitate cardiovascular magnetic resonance or computed tomography to
