An autopsy case of left ventricular apical ballooning probably caused by pheochromocytoma with persistent ST-segment elevation.

We describe the autopsy case of an 86-year-old man who experienced left ventricular (LV) apical ballooning with pheochromocytoma. During the follow-up period, his electrocardiogram (ECG) showed persistent ST-segment elevation in leads V3 to V6, and an echocardiogram revealed persistent LV dysfunction in the apical region. He died 64 days after admission. Pathological findings suggested catecholamine-induced cardiomyopathy and pheochromocytoma. This is the report of a rare autopsy case of LV apical ballooning.
