[Severe tricuspid valve injury following blunt chest trauma--case report].

Tricuspid valve (TV) injury is a rare complication of blunt chest trauma, most commonly as a result of a traffic collision. The authors describe a case of massive TV regurgitation due to a rupture of the chorde tendinae to the anterior and septal leaflets in a 21-year-old man, the victim of a car crash. Concomitant organ injuries included, among others, multiple rib fractures, pulmonary contusion, open femoral fracture. TV annuloplasty with Medtronic Duran ring implantation was performed one year after the accident because of right ventricular function worsening and occurrence of right heart failure symptoms. Three years after surgery only trivial TV regurgitation is detectable. The patient manifest good physical efficiency and continues occupational activity.
