Recurrent valvular pulmonary stenosis in patients with Tetralogy of Fallot (TOF) after corrective surgery is rare, with a few cases being reported. Repeat surgery is the usual management, and there is minimal experience with balloon valvuloplasty. Besides, the response of the reconstructed pericardial valve to balloon dilation is not known. We report valvular restenosis after TOF surgery in two patients, one of whom had a reconstructed pulmonary valve. The effectiveness of balloon valvuloplasty in these patients is discussed.
