Traumatic tricuspid regurgitation is a rare cardiovascular event that can follow blunt chest trauma. We report 2 cases of successful repair of traumatic tricuspid regurgitation. Case 1:a 22-year-old man. At 18 years of age, he was involved in a falling accident. At the age of 19, he had an abnormal electrocardiogram and a cardiac murmur pointed out on a medical examination in his university. Echocardiography revealed severe tricuspid regurgitation, and he was referred to our institution for surgery. The operative findings showed some fenestrations in the anterior leaflet of the tricuspid valve. The fenestrations were sutured directly and ring annuloplasty was performed. Case 2:a 54-year-old man. At age 18, he was involved in a falling accident. At age 31, he complained of fatigue and dyspnea. Echocardiography revealed severe tricuspid regurgitation. At age 54, liver dysfunction was discovered. He was referred to our institution for surgical treatment. In the operative findings, the chordae tendineae of the anterior and septal leaflets of the tricuspid valve were ruptured. Tricuspid valvuloplasty was performed using chordal replacement with 2 expanded polytetrafluoroethylene（CV-52®）sutures, edge-to-edge sutures and ring annuloplasty.
