Follow-up results of balloon angioplasty for native coarctation of aorta.
Balloon angioplasty of native discrete (< 1 cm) coarctation of thoracic aorta was performed in 29 patients [aged 13 to 31 years (mean 21.5 +/- 5.8 years), 22 males and 7 females], from March 1993 to December 1995. The patients were followed up for two years. After angioplasty, peak systolic arterial pressure (PSAP) decreased from 173.5 +/- 18.1 mm Hg to 122.5 +/- 9.9 mm Hg (p < 0.001), peak systolic pressure gradient (PSG) decreased by 90.9 percent from 86.2 +/- 15.77 to 7.77 +/- 3.8 mm Hg (p < 0.001) and the coarcted segment diameter increased about three times from 3.7 +/- 1.6 to 10.9 +/- 3.3 mm (p < 0.001). PSG decreased to < 10 mm Hg in 27 patients (93%) whereas in the other two patients PSG was 17 and 13 mm Hg. Restenosis appeared in 2 patients (6.8%); aneurysm in one patient (3.4%) which remained static even after 1.3 years of follow-up; mild dissection in 3 patients (10.3%); temporary femoral artery occlusion in 2 (6.8%) patients who recovered with heparin injection. Though hypertension disappeared after balloon dilatation in all patients, it reappeared in 3 patients (10.3%) within 7 days and in 10 patients (34.5%) within 6 months. In conclusion, balloon angioplasty of CoA is a good alternative to surgical correction.
