[So-called "ampulla" cardiomyopathy associated with coronary vasospasm compared with acute myocardial infarction showing similar abnormal left ventricular wall motion: two case reports].

So-called "ampulla" cardiomyopathy is characterized by transient abnormal left ventricular wall motion showing hypokinesia around the apical area and hyperkinesia at the basal area, without any detectable coronary lesion. We recently treated a patient with "ampulla" cardiomyopathy (Case 1) and a patient with acute myocardial infarction showing similar abnormal left ventricular wall motion (Case 2). A 75-year-old female (Case 1) presented with "ampulla" cardiomyopathy without coronary lesion.
