Unruptured left ventricular pseudoaneurysm following inferior wall myocardial infarction.

Left ventricular (LV) pseudoaneurysm is a rare but potentially lethal complication of acute myocardial infarction (MI). We report a very rare case of a 60 year-old woman with a ruptured myocardial wall, and a non-ruptured LV pseudoaneurysm. The patient presented with acutely worsening shortness of breath and exertional dyspnea of one month's duration, and palpitation. She had an inferior wall MI nine months previously. Coronary angiography showed severe stenosis at right coronary artery. Echocardiography, LV angiography, and computed tomography angiography revealed a large pseudoaneurysm postero-inferior to the LV. Surgical resection of the pseudoaneurysm was performed and repair of the ruptured LV wall done, with good results.
