[Late complications of a pseudo aneurysm of the left ventricle: thrombus infection and purulent pericarditis]. / Complications tardives d'un faux anévrisme du ventricule gauche: infection du thrombus et péricardite purulente.

Pseudoaneurysm is a rare complication of left ventricle myocardial infarction. Rupture with tamponade and sudden death is the usual outcome. Surgical intervention remains the treatment of choice. Long term survival cases without surgery are rare. Infection of the thrombus is also a possible event. We report the case of a patient with postinfarction left ventricular pseudoaneurysm complicated by infection of the thrombus and purulent pericarditis involving a peptostreptococcus. Infection must be considered a potential complication of left ventricular pseudoaneurysms.
