title: [Apical hypertrophic cardiomyopathy followed by midventricular obstruction and apical aneurysm: a case report].
abstract: A 72-year-old man presented with apical hypertrophic cardiomyopathy followed by midventricular obstruction and apical aneurysm. Doppler echocardiography revealed an abnormal blood flow from the apical aneurysm to the left ventricular outflow through the obstructive lesion during diastole. Myocardial perfusion scintigraphy showed no ischemic change in the apex. This case suggests that apical aneurysm may not be caused by ischemia, although previous reports showed ischemic degeneration or fibrosis may be a cause of an apical aneurysm.
