title: Clinical and echocardiographic aspects of mid-ventricular hypertrophic cardiomyopathy.
abstract: Three cases of patients with hypertropic cardiomyopathy, apical aneurysm, and mid-ventricular obstruction are presented. Two patients were diagnosed first by two-dimensional and Doppler echocardiography, which showed mid-ventricular obliteration, characteristic hourglass image, and paradoxic jet flow. One patient with suboptimal echocardiogram was necessary to perform contrast echocardiogram. Clinical picture was characterized by angina and dyspnea. Thallium myocardial imaging revealed perfusion abnormalities in apical region, ischemia or necrosis. Cardiac catheterism showed mid-ventricular obliteration and significant intraventricular gradient and coronary arteries angiography without lesions.
