title: Isolated right ventricular infarction presenting with anterior ST-segment elevation: a case for careful assessment of right ventricular branch occlusion.
abstract: We describe the case of a 61-year-old man who presented with chest pain and ST-segment elevation in the anterior precordial leads (V1-V5) due to proximal occlusion of the right ventricular branch of a codominant right coronary artery. Primary coronary angioplasty and stenting of this branch was performed resulting in resolution of the chest pain and ST-segment elevation. Our description illustrates a case of isolated right ventricular infarction as an uncommon but important differential diagnosis of anterior ST-segment elevation. In addition, it highlights the value of careful review of the angiographic images in this context, as the culprit lesion may be a right ventricular branch occlusion. To the best of our knowledge, this is the first reported case of primary percutaneous coronary intervention treatment of a right ventricular branch occlusion causing isolated acute right ventricular myocardial infarction and anterior ST-segment elevation.
