A right ventricular infarction disguised as an anterior infarction due to an occluded isolated right ventricular branch.

We report a case of abrupt closure of the right ventricular branch of the right coronary artery due to stenting. This closure caused marked ST-elevations in the precordial leads suggesting a problem in the left coronary artery. This phenomenon is scarcely reported in the literature. We discuss the typical electrocardiographic features of an isolated right ventricular infarction and we also give an anatomical model to elucidate them.
