Left ventricular giant pseudoaneurysm

Innovations (Phila). 2010 Jul-Aug;5(4):303-5. doi: 10.1097/IMI.0b013e3181effa1f.

Abstract

Left ventricular (LV) pseudoaneurysm is a rare complication of myocardial infarction. It may also occur as a complication of mitral valve surgery, chest trauma, and bacterial endocarditis. It forms when a cardiac rupture contains adherent pericardium or scar tissue and is typically located on the posterior or inferior LV wall. Pseudoaneurysms have a propensity to spontaneous rupture; hence, immediate surgical intervention is the treatment of choice for LV pseudoaneurysms diagnosed in the first months after myocardial infarction. The management of chronic LV pseudoaneurysms is still a subject of debate.
