[A case of posttraumatic tricuspid regurgitation-surgery combined with tricuspid valve repair and coronary artery bypass grafting].

A case of tricuspid regurgitation due to nonpenetrating chest trauma was presented. A 64-year-old female patient, who had a history of blunt chest trauma in a car accident 15 years ago, was admitted because of dyspnea on exertion and sensation of epigastric distress of 8 years duration. The patient's echocardiogram and right ventriculogram "demonstrateol massive tricuspid regurgitation and enlargement of both the right atrium" and the right ventricle. Additionally the coronary arteriogram showed severe stenotic lesion of the proximal left anterior descending coronary artery. The patient underwent reconstructive surgery for the tricuspid valve combined with coronary artery bypass grafting using a left internal mammary artery graft successfully. The torn chordae tendinae of the anterior and posterior leaflet were reattached to the leaflet edges with polytetrafluoroethylene (PTFE) sutures and the size of a dilated annulus was reduced using 30 mm Carpentier ring.
