Correction of tetralogy of Fallot in an adult using a stented bioprosthetic valved conduit

A 55-year-old man with tetralogy of Fallot successfully underwent correction using a valved conduit. He was diagnosed as having congenital heart disease during childhood, but no surgical intervention was performed. Cyanosis and dyspnea on effort had progressed gradually. Catheterization showed a left ventricular end diastolic volume of 126 ml, and the pulmonary arteries had sufficient diameters. To prevent postoperative pulmonary regurgitation, we planned to use a bioprosthetic valved conduit for right ventricular outflow tract reconstruction. At 4.5 years after the operation he is in New York Heart Association functional class I. The catheterization performed 1.5 years after the surgery showed no pressure gradient between the right ventricle and the pulmonary artery. Thus, total correction of tetralogy of Fallot in an adult can be achieved safely, and the use of a bioprosthetic stented valved conduit can be beneficial.
