ST Segment Elevation Right Ventricular Myocardial Infarction due to Isolated Right Ventricular Branch Occlusion During Right Coronary Artery Stenting

Abstract

Isolated right ventricular (RV) myocardial infarction (MI) is an extremely rare phenomenon and may be difficult to recognize. Also, it is rare to observe ST elevation in anterior leads caused by isolated, transient small acute marginal branch occlusion. We described the case of an acute RV MI with transient ST segment elevation in precordial leads from V1 to V4, due to isolated RV branch occlusion during right coronary artery stenting. Figure 1: The basal Ecg shows normal ST-T segment in the inferior leads and minimal ST segment depression in the precordial leads.
