Hypertrophic cardiomyopathy associated with left ventricular noncompaction cardiomyopathy and coronary fistulae: a case report. One genotype, three phenotypes?

Abstract

The authors present a rare case of hypertrophic cardiomyopathy associated with left ventricular noncompaction cardiomyopathy and coronary artery-left ventricular fistulae in a 42-year-old woman presenting with non-ST-elevation myocardial infarction. Coronary angiography, transthoracic echocardiography and cardiac magnetic resonance revealed the structural abnormalities of the left ventricle and the coronary tree.
