Tricuspid valve dysplasia may be present in pulmonary atresia with intact ventricular septum however it is an extraordinary situation in pulmonary stenosis. In this study, we reported a case with pulmonary stenosis assosiated with dysplastic tricuspid valve. During the operation, tricuspid valve dysplasia was found. The valve margins were attached directly to the papillary muscles without chordal development. There was one commissure but the other ones were undeveloped. In addition to atrial septal defect closure, and pulmonary valvotomy, tricuspid valve repair was performed. Postoperatively, complete improvement was achieved.
