“…Overall, procedural success was acutely 91.3% with cumulative intermediate-term success being 87% at 1 month (Table 4) and 82.7% late 14 months mean follow up. Mortality following stent implantation for coarctation has been zero in all previous studies 11,12 as well as in the present study. Potential stent related complications include incomplete stent expansion, stent fracture, distal migration, and thromboembolic episodes.…”

Background: Coarctation of the aorta occurs in about 6% to 8%of patients with congenital heart disease Surgery, balloon dilatation, and stent implantation have all proven effective in the treatment of moderate or severe obstruction. Objective: Assess the initial and intermediate term results of stent implantation in all age groups with both native and recurrent coarctation of aorta. Patients and design: A total of 23 patients (14 [65.4%] males and 9 [34.6%] females) with congenital COA who had undergone aortic stenting angioplasty were recruited. Nineteen (82.6%) of these patients had native COA and four (17.38%) had recurrent COA.(one after previous coarctation stenting with stent fracture and three after balloon dilatation). Clinical data was collected at baseline, before discharge, and at follow-up and included upper and lower extremity systolic/diastolic blood pressure, as well as the need for antihypertensive medication , and echocardiographic data like COA gradient, associated lesions and concentric LVH. During procedure pre and post cath gradient across coarctation segment taken, along with assessment for any complications. Results: Immediately after stent implantation the peak systolic cath gradient (mean (SD)) fell from 61.6 (13.3) to 8.1 (3.6) mm Hg (p = 0.00). The diameter of the stenotic lesion increased from 4.58 (0.5) mm to 14.8 (1.3) mm (p < 0.05). There were no deaths or procedure related complications. Only one patient (4.34%) developed early complications. Acute procedural success was 91%. During the follow-up of one month 3 (13%) of the patients had re-stenosis. At a mean follow up of 14 months, 4 cases of re-coarctation were identified echocardiographically and 43.47% had chronic systemic hypertension, requiring drug therapy. Conclusions: Stent implantation for the treatment of coarctation of the aorta appears to have very low morbidity and mortality, and good intermediate term results. Endovascular stenting could be an effective and safe method, even in all age group of patients with native and recurrent COA.

“…3 Balloonexpandable endovascular stents have been used successfully as primary treatment for coarctation and recoarctation. 4,5 The concept of endovascular stent-grafts for secondary repair of postsurgical aneurysm, however, has not been tested. This alternative was subsequently used to avoid repeat surgery for postcoarctation aneurysm in 6 consecutive cases.…”

Background-Formation of aortic aneurysm late after surgical repair of coarctation carries a significant risk of rupture and lethal outcome, and repeat surgery is associated with a 14% in-hospital mortality rate and morbidity from paraplegia, injury to the central nervous system, or from bleeding. The potential of nonsurgical endovascular repair by the use of stent-grafts in lieu of repeat surgery for postcoarctation aneurysm is unknown. Methods and Results-The concept of postsurgical endovascular stent-graft placement was evaluated with respect to feasibility and safety in 6 consecutive patients with late aneurysm formation after coarctation repair. All patients had aneurysm formation late after patch aortoplasty; placement of an elephant trunk during surgical repair of secondary type I dissection preceded formation of a local aneurysm in 2 cases. Patient age was 49Ϯ12 years, ranging from 31 to 68 years. Transluminal placement of customized stent-grafts was successful, with no 30-day or 1-year intervention-related mortality or morbidity. Follow-up survey of 11 to 47 months revealed optimal reconstruction of the thoracic aorta; 1 patient died 11 months after endovascular repair from cancer. Conclusions-Nonsurgical
