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®) 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.

A 67-year-old man was admitted with heart failure. He had a past history of closed chest trauma due to a traffic accident at the age of 24. He had been complaining of a gradual increase of fatigue since a few years after the accident and received medical treatment. At approximately 40 years of age, he underwent cardiac catheterization and was given a diagnosis of Ebstein malformation. However surgery was not recommended. An echocardiogram showed a laceration at the tricuspid valve, enlargement of the tricuspid valve annulus and severe tricuspid regurgitation. The displacement of tricuspid valve was not present. His case was complicated with severe liver dysfunction of Child-Pugh class B and Model for End-Stage Liver Disease score 15. We performed tricuspid valve replacement with a Mosaic 31 mm tissue valve. The patient required pleurodesis for refractory severe pleural effusion at 2-months and was discharged 6 months after the operation.

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<sup>®</sup>) sutures, edge-to-edge sutures and ring annuloplasty.
