Ruptured chordae tendineae of the posterior leaflet of the tricuspid valve as a cause of tricuspid regurgitation following blunt chest trauma.
A 12-year-old boy suffered a blunt chest trauma. Some hours later, a pulsatile bilateral jugular venous distension, a holosystolic murmur heard at the low parasternal border and hepatomegaly were observed. On echocardiography, ruptured chordae tendineae of the posterior leaflet of the tricuspid valve, as well as tricuspid regurgitation were detected. He remained asymptomatic during hospital stay and was discharged home in good condition. Thus, isolated ruptured chordae tendineae of the posterior leaflet of the tricuspid valve is another cause of tricuspid regurgitation following blunt chest trauma.
