A surgical case of left ventricular pseudoaneurysm complicating myocardial infarction in a diabetic patient on dialysis.

A 57-year-old man was hospitalized with dyspnea and heart failure. We performed an electrocardiogram, coronary angiogram, echocardiogram, and magnetic resonance imaging. He was diagnosed with a left ventricular pseudoaneurysm (i.e., heart tumor) at the posterolateral wall. Minimal contrast medium was utilized when making the diagnosis as the patient was on dialysis. We subsequently repaired the ventricular unruptured pseudoaneurysm and performed a coronary artery bypass grafting. This case presented difficulty in ascertaining the difference between a cardiac tumor and a ventricular pseudoaneurysm.
