Abstract
Despite the increased success rates of surgery of congenital heart diseases in the last decades, anatomical complications occur after repair procedures. The correction of these complications by transcatheter therapy has improved the outcomes of these patients and abolished risks due to reoperation (1-3). Branch pulmonary artery stenosis may occur either congenitally or as a complication of surgery of various congenital heart diseases, as mentioned above. Tetralogy of Fallot (TOF) seems to be the most common cardiac lesion in the series involving transcatheter treatment of branch pulmonary artery stenosis (2, 4). Transcatheter treatment of stenotic pulmonary arteries via balloon-expandable intravascular stents was first tried by Mullins et al in the late 1980s (5). The aim was to dilate areas of stenoses using angioplasty balloons matched to the appropriate size of the adjacent vessel and to provide a support structure at the area of stenosis to prevent recoil. Since then, the transcatheter technology has improved rapidly enabling correction of most of the stenotic lesions without the need of operation. In this report, we present a case with TOF who developed stenosis of the left pulmonary artery (LPA) after repair surgery. The stenosis was managed successfully by stent replacement after a trial of balloon angioplasty.
