Background: coarctaion of aorta occur in 6 % of patient with congenital heart disease, balloon dilation, stenting and surgery have been proved as modality of treatment coarctaion of aorta. Usually untreated coarctation of aorta may lead to renal, vascular and cardiac complication that start to appear at binging of fourth decade of life.
Aim: Mortality and morbidity rate among patients use uncover stent in treating adult coarctaion of aorta and short term outcome.
Patient and method: 75 patients with coarctaion of aorta 30 male (40%) and 45 female (60 %) was involve in this prospective longitudinal study, there age range from 16 to 41 year, for all echocardiography, CT chest done to confirm diagnosis then all undergo catheterization of aorta with 2 sheath one femoral and other radial to measure pressure gradient across stenosis and stent localization follow by stenting with pre and post dilation if needed then measure pressure gradient across stent.
Result: all patients stent by uncover stent including for 2 case with interrupted coarctaion, immediately after stent pressure gradient fall almost all our patient then follow up 6 month, 1 year by angiography assessment with CT chest show no stent fracture or aneurysm in aorta at stent site.
Conclusion: uncovered stent appear to be safe in treating coarctaion of aorta with less morbidity and mortality. It has advantage that no Side branch loss especially in case of coarctaion at subclavian artery (preductal). It required small femoral sheath size (less than 11 French) so less access site complication.
