Rotura de válvula tricúspide con insuficiencia masiva secundaria a traumatismo torácico cerrado: caso clínico / Massive tricuspid valve insufficiency after blunt chest trauma: report of one case

ABSTRACT

Cardiac valve lesions after a blunt chest trauma are rare and less than 1 percent of cardiac lesions because of chest trauma affect the tricuspid valve. We report a 70 year-old female that suffered a severe chest trauma in a car accident. Duríng the repair of the múltiple skeletal lesions, the patient had a severe hemodynamic decompensation. A myocardial trauma with pericardial effusion and massive tricuspid insufficiency, due to anterior leaflet prolapse, was diagnosed on echocardiography. After discharge the patient remained in functional class II, with hepatomegaly, jugular ingurgitation and lower limb edema. A control echocardiogram, perfomed six months after the accident, showed dilatation of right heart chambers and massive tricuspid insufficiency. The patient was operated, and a tricuspid valve repair was performed suturing the ruptured papillary muscle to the ventricular wall and performing a triscuspid annuloplasty with a prosthetic ring. After 15 months of follow up, the patient remains asymptomatic.
