title: [A successful surgical repair of congenital mitral stenosis due to commissural papillary muscle fusion].
abstract: A case of congenital mitral stenosis, patent ductus arteriosus, pulmonary hypertension was reported. At one year of age, the patient underwent surgical division of PDA because of persistent left heart failure. She went well after the operation. At seven year of age, she was readmitted to our hospital for easy fatigability. The cardiac catheterization revealed remarkably elevated pulmonary arterial pressure and pulmonary capillary wedged pressure. She underwent a surgical intervention for the mitral stenosis at eight year of age. At operation, the mitral valve exhibited the characteristics of type IIc according to Carpentier's classification: thickened and dysplastic leaflet, extremely short chordae tendanae fused with papillary muscles, obliteration of interchordal space and hypertrophic two papillary muscles. We replaced the valve with 23 mm Carbomedicus prosthetic valve because it seemed to be difficult to repair the native valve satisfactorily without residual stenosis or insufficiency. Her postoperative course was uneventful and the pulmonary arterial pressure and pulmonary capillary wedged pressure decreased remarkably one year after the operation.
