OBJECTIVES: We evaluated the procedural success and short-mid term results of stent implantation for aortic coarctation in adults.
STUDY DESIGN: The study included 15 consecutive patients (9 women, 6 men; mean age 27±7 years; range 17 to 45 years) treated with stent implantation for aortic coarctation. Fourteen patients had native, one patient had recurrent coarctation. Nine patients received bare metal and six patients received covered Cheatham-Platinum stents. Covered stents were used in patients with accompanying patent ductus arteriosus (n=2), severe coarctation (n=3), and recurrent coarctation (n=1). Procedural success was defined as the reduction in the pressure gradient across the coarctation site to less than 20 mmHg. The mean follow-up period was 10.4±4.6 months (range 3 to 18 months).
RESULTS: Stent implantation was successful in all the patients. Compared to the preprocedure figures, systolic gradient across the aortic coarctation decreased from 37.2±11.3 mmHg to 3.5±2.9 mmHg, the diameter of the coarcted aortic segment increased from 5.4±1.5 mm to 17.2±1.4 mm, and systolic blood pressure declined from 154±9.7 mmHg to 130±7.3 mmHg following stenting (for all, p<0.001). There were no procedure-related major complications.
CONCLUSION: Stent implantation for aortic coarctation in adults is a safe and effective alternative to surgical correction.
