Isolated left ventricular noncompaction in a patient presenting with a subacute myocardial infarction

Isolated left ventricular noncompaction is a rare cardiomyopathy that is often not recognised. So far, it is not well established how best to manage this abnormality. We describe a patient in whom the diagnosis of isolated left ventricular noncompaction was made after presentation with a subacute myocardial infarction. Because of nonsustained ventricular tachycardias during hospitalisation, which were inducible and deteriorated into ventricular fibrillation on electrophysiological examination after coronary artery bypass grafting, he received an implantable defibrillator. Whether the ventricular tachycardias were due to the myocardial infarction or to the noncompacted myocardium remains uncertain. (Neth Heart J 2007;15:109-11.).
