Primary angioplasty for isolated right ventricular infarction

We describe a case of isolated right ventricular infarction that has rarely been diagnosed antemortem. Electrocardiogram showed ST segment elevation i n left precordial chest, right precordial chest, and inferior leads, which mimicked those of anterior and inferior left ventricular infarction. Corona ry angiography revealed that culprit lesion was totally occluded right coro nary artery. Infarcted artery was nondominant right coronary artery with br anches supplying only right ventricular wall. Restoration of coronary blood flow was obtained by primary stenting and resulted in prompt ST segment no rmalization in all leads. Despite extensive right ventricular wall motion a bnormality, subsequent right ventricular dysfunction was not observed. (C) 2001 Wiley-Liss, Inc.
