Right ventricular (RV) infarction usually occurs in the setting of inferior wall myocardial infarction due to proximal right coronary artery (RCA) occlusion. A rarer cause of RV infarction involves an isolated RV branch occlusion during a percutaneous coronary intervention (PCI) to revascularize the RCA. In this case, the isolated RV branch occlusion resulted in transient unexpected ST-segment elevations in the anterior precordial leads. The patient developed transient chest pain peri-procedurally and repeat angiography showed widely patent stents but complete occlusion of the isolated RV branch. This case highlights a rare and unusual presentation of RV branch occlusion with anterior ST-segment elevations.
