Balloon coarctation angioplasty: follow-up of 103 patients.

ABSTRACT

OBJECTIVE: To evaluate the role of balloon coarctation angioplasty (BCA) in the management of patients with native coarctation of the aorta. BACKGROUND: BCA has emerged as an alternative to surgery for patients with native coarctation of the aorta. However, its role remains controversial. METHODS: Over a 7-year period, 103 patients undergoing BCA were enrolled in the study. Hemodynamic evaluation was obtained at baseline and immediately following BCA; 75% of patients returned for follow-up evaluation at 26 +/- 20 months. RESULTS: The systolic gradient across the coarcted segment decreased from 59 +/- 18 mmHg to 10 +/- 11 mmHg following BCA (p < 0.001). The procedure was successful in 82% of patients, and partial improvement was obtained in 17%. Repeat intervention was performed in 13% of the follow-up group. Surgical intervention was needed in 8 patients. CONCLUSION: Balloon angioplasty is an effective first-line intervention in patients with native coarctation of the aorta.
