Acute Myocardial Infarction Caused by an Anomalous Right Coronary Artery Occlusion Presenting with Precordial ST Elevation

Bruno da Silva Matte et al. Case Rep Cardiol. 2017.

Abstract

Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1-V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thrombotic occlusion resulting in right ventricular infarction with precordial ST elevation and sinus node dysfunction. The patient was treated with successful rescue angioplasty achieving resolution of acute symptoms and electrocardiographic abnormalities.

Post-PCI angiogram. RCA seen in both LAO (a) and RAO (b) views. Good poststenting result in proximal RCA (TIMI 3) but slow flow (TIMI 2) in RV marginal branches. RCA: right coronary artery; LAO: left anterior oblique; RAO: right anterior oblique; TIMI: thrombolysis in myocardial infarction; RV: right ventricular.
