Abstract

Background Bare stents has become the first line therapy for aortic coarctation. Covered stents has been reported more recently in clinical practice. Objectives The present study, reports comparatively 15-year experience of bare and covered stent implantation for aortic coarctation in a single tertiary referral center. Methods From 1997 to 2011, 143 patients with native or postoperative aortic coarctation were treated at our institution. Seventy-one subjects (median age 17 years (range from 4 to 70 years) underwent bare stent implantation (Group 1) while 72 patients (median age of 17.5 years (range from 6 to 68 years) underwent covered stent implantation (Group 2). Results Success rate in the whole group was 95%. More complex and tighter coarctations were treated using covered stents. Incidence of related-procedure adverse events was higher in Group 1 than in group 2 (21.1% vs 8.3% P=0.035). Aortic wall complications occurred in 7% of patients in Group 1 (one death) and 0% in Group 2 (P=0.028). Subjects in Group 1 had a longer follow-up (median 85 vs 35 months; P10 mm Hg (HR: 4.30; CI: 1.96-9.47). Conclusions Both bare and covered stent implantation for aortic coarctation is a safe and efficacious treatment. By using covered stent implantation the spectrum of patients treated has increased with lower rates of acute and late complications.
