[Persistent left ventricular systolic dysfunction in a patient with ampulla cardiomyopathy: a case report].

An 81-year-old woman was admitted for treatment of diastolic heart failure. Two weeks after admission, she suffered sudden chest pain without somatic and/or psychological stress. Electrocardiography showed ST elevation in leads V2- V5. Coronary angiography did not reveal any significant stenosis in the epicardial coronary artery. Left ventriculography showed apical akinesis with basal and mid hyperkinesis. The diagnosis was ampulla cardiomyopathy. The abnormality on electrocardiography was normalized 2 months later, but apical akinesis persisted for 1 year. Myocardial contrast echocardiography showed microvascular dysfunction consistent with the apical akinesis for 1 year. Microvascular dysfunction may be important in the pathophysiological state of ampulla cardiomyopathy.
