Abstract:
Ten patients, aged 3 to 43 years, with the tetralogy of Fallot underwent in situ pulmonary valve replacement (PVR) 13 times. The implanted valves were a St. Jude Medical prosthesis (3 times) and a bioprosthetic valve (10 times). In 5 patients PVR was performed at the time of radical repair and in the remaining 5 patients PVR was performed after radical repair. Three patients underwent re-PVR at 6 to 13 years after the first PVR. There was one operative death in re-PVR 14 years after the first PVR and one patient died from congestive heart failure 4 years after PVR. In the patients with the tetralogy of Fallot, the rate of PVR in those who had undergone open Brock's operation were significantly higher than that of the patients without open Brock's operation (p<0.05). Actuarial survival rates at 5 years and 10 years were 88.9% and 88.9%, respectively. Rates of freedom from reoperation at 5 years and 10 years were 88.9% and 59.3%, respectively. Although the early operative results are satisfactory, re-PVR is mandatory in the future. Thus the indications of PVR should be considered carefully.
