Free wall rupture after a myocardial infarction may rarely cause a left ventricular (LV) pseudoaneurysm to develop. LV pseudoaneurysms are most commonly discovered incidentally on echocardiography and require a high index of suspicion to diagnose. We report the case of a 73-year-old male who experienced an asymptomatic myocardial infarction leading to cardiac arrest after placement in the Trendelenburg position. During resuscitation efforts, he was discovered to have an LV pseudoaneurysm on transthoracic echocardiogram. We report an unusual presentation of LV pseudoaneurysm and discuss a possible link between Trendelenburg position and the development of LV pseudoaneurysm.
Keywords: false aneurysm; free wall rupture; left ventricular pseudoaneurysm; myocardial infarction; trendelenburg.
