A 62-year-old man was referred to our hospital because of dyspnea. Electrocardiogram showed chronic atrial fibrillation and echocardiogram revealed severe tricuspid regurgitation. His history included a motorbike accident at age 17, and a heart murmur was pointed out in the following year. He developed paroxysmal atrial fibrillation when he was 45 years old. Heart failure was not controlled by medication and tricuspid valve repair was indicated. At surgery, the anterior leaflet of tricuspid valve was widely prolapsed due to chordal rupture. We performed chordal reconstruction with 4 expanded polytetrafluoroethylene（CV-5●R）sutures, and ring annuloplasty. Furthermore, a small fenestration at the tricuspid annulus was noticed and was closed with a direct suture. The biatrial modified Maze procedure was performed subsequently. The patient is doing well without TR recurrence, and restored sinus rhythm is maintained. We report successful repair of traumatic tricuspid regurgitation.
