Successful Primary Percutaneous Intervention with Stenting in Anomalous Right Coronary Artery Arising from left Coronary sinus in case of Acute Inferior wall Myocardial Infarction Complicated by Cardiac Tamponade

Abstract

Anomalous origin of the right coronary artery (RCA) from the left sinus of valsalva is a rare congenital abnormality. The unusual location and noncircular orifice of this anomaly poses a great technical challenge for selective catheterization and percutaneous coronary intervention (PCI). Hemopericardium leading to tamponade complicating acute MI is rare and leads to hemodynamic instability. We report a case of acute inferior wall MI with a moderate pericardial effusion in cardiac tamponade who was treated with
immediate pericardiocentesis followed by PCI and stenting of an anomalously arising RCA from the left sinus.
