Traumatic tricuspid regurgitation.

Tricuspid valvular insufficiency caused by blunt thoracic trauma may be clinically silent and imprecise. Diagnosis is often done by cardiac catheterization and two-dimensional echocardiography (2-DE); the latter may show abnormalities of the tricuspid leaflet motion. The surgical technique for its correction is still controversial. We report here the case of an eighteen year old man who was involved in a high-speed motorcycle accident. Seven months later, due to dyspnoea and fatigue, 2D-E examination revealed cardiac enlargement and severe tricuspid regurgitation. Surgery was indicated in order to repair valve incompetence. Reinsertion of the chordae tendineae at the anterolateral papillary muscle and annuloplasty was performed and ten months postoperatively, he is in good clinical condition and 2D-E control shows a trivial residual tricuspid insufficiency.
