| Popis: | Objectives. This study was designed to assess the success rate and determinants of success or failure of balloon angioplasty for postoperative pulmonary stenosis in patients with transposition of the great arteries.Background. Previous reports have suggested that pulmonary stenosis that develops after the arterial switch operation is not likely to be dilated.Methods. Twenty-eight patients with transposition of the great arteries underwent 39 balloon angioplasty procedures after the arterial switch operation. The mean age at dilation was 4.5 ± 2.2 years (range 0.7 to 9.8), and the interval between operation and balloon dilation was 3.6 ± 1.8 years. The criterion of successful dilation was a ≥50% increase in predilation diameter or a ≥50% decrease in predilation pressure gradient. If the right ventricular/ aortic pressure ratio decreased by ≥0.2, so that the ratio became |
