Patients with complex congenital heart defects may have different hemodynamic prob-lems which require a variety of interventional procedures including angioplasty which involves using high-pressure balloons. After failure of conventional balloon angioplasty, cutting balloon angioplasty is the next treatment option available. The purpose of this study was to evaluate the safety and efficacy of cutting balloon angioplasty in children with different types of congenital heart defects.
Cutting balloon angioplasty was performed in 28 children with different congenital heart defects. The indication for cutting balloon angioplasty was: pulmonary artery stenosis in 17 patients, creating or dilatation of interatrial communication in 10 patients, and stenosis of left subclavian artery in 1 patient.
In the pulmonary arteries group there was a significant decrease in systolic blood pressure (SBP) in the proximal part of the artery from the average 74.33 ± 20.4 mm Hg to 55 ± 16.7 mm Hg (p < 0.001). Distal to the stenosis there was an increase in SBP from 19.8 ± 3.82 mm Hg to 30.3 ± ± 13.3 mm Hg (p = 0.04). This result remained constant in the follow-up. In atrial septal defect/fenestra-tion group, cutting balloon angioplasty was performed after an unsuccessful classic Rashkind procedure. After cutting balloon angioplasty there was a significant widening of the interatrial communication.
Cutting balloon angioplasty is a feasible and effective treatment option in different con-genital heart defects.
