[Right ventricular outflow obstruction due to accessory tricuspid valve tissue in corrected transposition of the great arteries with ventricular septal defect].
A 27-year-old man known to have corrected transposition of the great arteries (CTGA) associated with a ventricular septal defect (VSD) was admitted to our hospital with a suspected increase of the shunt volume. The patient is a first class bodybuilder. Heart catheterization confirmed the diagnosis of a "right-ventricular" mass obstructing the "right-ventricular" outflow tract, which had already been seen at echocardiography. The intraoperative finding showed the tumor to be accessory tissue of the anterior tricuspid leaflet prolapsing through the VSD into the subvalvular outflow tract of the right ventricle. The accessory tricuspid valve tissue was removed by transatrial access. The VSD was closed by a dacron patch using the same route. The postoperative course was uneventful.
