Abstract

We report the case of an 8-year-old patient with severe acute mitral regurgitation and tricuspid regurgitation after a motor vehicle collision caused by traumatic injuries of the supporting structures of both valves. An echocardiogram showed avulsion of the posteromedial papillary muscle of the mitral valve and a severely prolapsed anterior tricuspid valve leaflet. In addition, there was a near-complete defect in the left ventricular side of the interventricular septum, with diffuse hematoma of the akinetic septal muscle. After emergency mitral and tricuspid valve repairs, consisting of re-implantation of the posteromedial papillary muscle and anterior tricuspid leaflet chordal support, the patient completely recovered with no residual valvular pathology.
