    Abstract:
    Case 1: A 52-year-old man presented with a chief complaint of palpitation. Diabetes mellitus was pointed out in 1992. Electrocardiography (ECG) revealed left ventricular hypertrophy in 1997. He visited our department in October 1997. Echocardiography showed increased wall thickness at the interventricular septum. The diagnosis was hypertrophic cardiomyopathy. Holter ECG revealed nonsustained ventricular tachycardia in December 1997. After this, he visited our outpatient clinic. Echocardiography indicated ventricular aneurysm in January 2002, so he was hospitalized in March 2002. Case 2: A 64-year-old woman was transferred to our hospital because of chest discomfort and tachycardial attack. She had been treated for hypertension and diabetes mellitus. She was taken to a hospital by ambulance. On admission, ECG showed wide QRS tachycardia. Cardiac magnetic resonance imaging in both patients disclosed almost complete obstruction of the mid-ventricle in the systolic phase on long- and short-axis cine images, and gadolinium delayed imaging revealed contrast hyperenhancement corresponding to an apical ventricular aneurysm on both long- and short-axis images. The final diagnosis was mid-ventricular obstructive hypertrophic cardiomyopathy with apical aneurysm characterized by delayed hyperenhancement on magnetic resonance imaging with gadolinium.
