A rare malady with a rarer complication.

Isolated ventricular noncompaction (IVNC) is an unclassified cardiomyopathy characterized by prominent intraventricular trabeculations separated by deep intertrabecular recesses. Although microvascular dysfunction is known, myocardial infarction is rare and usually seen as a consequence of coincidental coronary artery disease. We report the case of a 19-year-old male patient who presented to us with symptoms and signs of heart failure. Echocardiography revealed IVNC with severe left ventricular dysfunction. He was put on medical treatment including oral anticoagulants. Six months later, he came to our emergency department with anterior wall STEMI. Coronary angiogram revealed thrombotic occlusion of distal LAD, which resolved completely with tirofiban and heparin. Coronary thromboembolism due to blood stasis in the left ventricular cavity has not been previously documented in IVNC.
