ABSTRACT
Congenital mitral regurgitation (MR) occurs infrequently and the number of reported adult surgical cases is small. A 77-year-old man presented with an exacerbation of congestive heart failure. He had a 19-year history of receiving medical treatment for MR and atrial fibriration. Transthoracic and transesophageal echo cardiograms revealed severe MR due to the restriction of the posterior mitral leaflet with very short chorda tendanea attached beneath the posterior leaflet preoperatively. We diagnosed this case to have congenital MR (Carpentier type III) in an adult based on the specific findings of echocardiography and mitral valve plasty was thus performed. All the dysplastic chordae of the P2 and P3 in the immovable leaflet region were cut and the reconstructed by the fifth artificial chordae. These procedures successfully allowed the posterior mitral leaflet to recover its normal shape and movability. Postoperative echocardiography showed no further mitral regurgitation and normal leaflet motion.
