Traumatic Tricuspid Regurgitation Caused by Myocardial Laceration: A Three-Dimensional Echocardiographic Study

published online 11 February 2010.

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.
