Iatrogenic Left Main Coronary Artery Stenosis Following Aortic and Mitral Valve Replacement: A Case Report

Iatrogenic coronary artery disease following prosthetic valve implantation is a rare complication. This may result from mechanical injury in the intraoperative period. Once the diagnosis of coronary ostial stenosis is established, the procedure of choice is coronary artery bypass surgery. We report a case of a young lady who underwent aortic and mitral valves replacement. Six months later she was then diagnosed with ostial left main stem coronary stenosis after presenting with non-ST elevation MI. The patient eventually underwent PTCA.
