A 19-year-old man was admitted for severe traumatic tricuspid regurgitation (TR) 4 months after a traffic accident. Transthoracic echocardiography revealed severe TR, with an abnormal chordal structure. Three-dimensional echocardiography showed widely lacerated right ventricular endocardium involving many subvalvular components. In this case of traumatic TR, three-dimensional echocardiography was useful not only for its diagnosis but also in providing important information for surgical decision making.
一名 19 岁男性因交通事故后 4 个月出现严重创伤性三尖瓣反流（TR）而入院。经胸超声心动图显示严重 TR，伴有异常腱索结构。三维超声心动图显示右心室心内膜广泛撕裂，累及多个瓣下结构。在这种创伤性 TR 的情况下，三维超声心动图不仅有助于诊断，而且还为手术决策提供了重要信息。
