Abstract
We here present the case of a 35-year-old man with mitral valve paravalvular abnormal tunnel with mitral regurgitation caused by anterior chest trauma. The abnormal tunnel is between left ventricular and left artrial. We sutured the tunnel with a patch from the left atrial side. Meanwhile, we performed the mitral valve annuoplasty because of the mitral regurgitation accompanied. The postoperation and the 12th month follow up were uneventful.
