Post-surgical right coronary artery injury secondary to tricuspid valve repair

Abstract

Injury to the right coronary artery (RCA) is a rare complication of tricuspid annuloplasty. We report a 64-year-old woman with history of valvular heart disease that was admitted for decompensated right heart failure. The patient underwent aortic valve replacement and tricuspid annuloplasty. Shortly after tricuspid annuloplasty the patient developed right ventricular (RV) infarction with hemodynamic compromise. The coronary angiogram shows subtotal occlusion at the mid segment of right coronary artery probably due to stitch of the tricuspid ring. The RCA has successfully been revascularized by percutaneous coronary angioplasty with bare metal stent, however the patient got into multi-organs failure syndrome and died at day 15 postoperatively.
