A 48-year-old male was admitted with chief complaints of fatigue and palpitation. He had a past history of closed chest trauma without rib fracture due to an automobile accident 7 years ago. He had been complaining of a gradual increase of palpitation since 4 years after the accident. A two-dimensional and transesophageal Doppler echocardiography revealed severe tricuspid regurgitation due to ruptured chorda tendinea of the tricuspid anterior leaflet. Cardiac catheterization revealed an elevated right atrial v wave (16 mmHg). At open heart surgery, complete tear of a chorda tendinea of the anterior leaflet and elongation of chordae tendineae of the posterior leaflet were observed. The valve was replaced with a 31 mm Carpentier-Edwards bioprosthesis. His post operative course was uneventful. A brief review of the reported surgical cases of traumatic tricuspid regurgitation in Japan is also described in this paper.
一名48岁男性因疲劳和心悸为主诉入院。他有7年前因车祸导致的无肋骨骨折的闭合性胸部外伤史。自事故发生4年后，他一直抱怨心悸逐渐加重。二维和经食管多普勒超声心动图显示由于三尖瓣前叶腱索破裂导致严重的三尖瓣反流。心导管检查显示右心房v波升高（16 mmHg）。在心脏直视手术中，观察到前叶腱索完全撕裂和后叶腱索延长。瓣膜被替换为31毫米的Carpentier-Edwards生物假体。他的术后过程顺利。本文还简要回顾了日本报道的创伤性三尖瓣反流的手术病例。
