[Accessory tricuspid valve--a report of two cases].

Accessory tricuspid valve is a rare cardiac anomaly. We describe two cases with accessory tricuspid valve. Case 1: A 7-year-old boy underwent repair of tetralogy of Fallot. Under deep hypothermic cardiopulmonary bypass, right ventricle was opened. An accessory tricuspid leaflet was noted to the right side of the VSD attaching to the infundibular septum from medial papillary muscle as a chordal origin. After excision of the accessory tricuspid leaflet, the VSD was closed with a Dacron patch followed by relieve of the right ventricular outflow obstruction and pulmonary valvotomy. Case 2: A 8-year-old boy had Rastelli operation to correct transposition of the great arteries. An accessory leaflet originated from the medial papillary muscle and was floating like a parachute in the way between VSD and aorta. There was no additional apparatus in the pathway between the VSD and aorta after excision of the accessory tricuspid leaflet. Intraventricular tunnel was created with a Dacron patch. Extracardiac conduit between the right ventricle and the distal pulmonary artery was constructed using a valved pericardial roll.
