Abstract
This study is on different surgical techniques for repair of Co-arctation of aort and their effect for correction of systemic hypertension and lower extremity hypotension. In addition to these, the clinical and paraclinical data were noticed. 50 pt were operated in "SHARIATI" hospital during 1370-1377 with diagnosis of Co-arctation of aorta (30 men, mean age 19.4 years, 20 women, mean age 16.6 years). In addition to older age of our patients which results in more post-op sequela, there was suprrisingly a long-lag between onset of symptoms, diagnosis and operation (mean 4.36 years). 62% of Co-arctation were juxtaductal and the remainder were non-classical forms. 52% of our patients had co-existing cardiac disease which were very high in comparison with other studies (12%). This is due to older age of our patients and more valvular heart diseases. Among complicated cases of co-arctation, 71.9% were in men and 28.1% in women and this difference is due to high incidence of bicuspid aortic valve in men. The mean angiographic gradient were 57.5 mmHg which increases with age. CXR was abnormal in 91.7% and ECG in 74.2% of patients. The different applied surgical techniques include ee-A=26%, TIG=40%, TBG=18%, DPR=14%, FSCR=2%. There is no significant difference regarding post-op complications, BP in post-op period, and increase in pedal pulses, except in TBG group which HTN was more common. Two early deaths occurred which were in DRP group.

Abstract
Background: Coarctation of aorta is narrowing of proximal descending aorta. Interventional procedures such as balloon angioplasty & stent implantation has been progressively in use as alternatives for surgery in increasing number of children with diagnosis of coarctation of aorta. The aim of this study was to evaluate the use of endovascular stent in children with coarctation of aorta.
Methods: We evaluated effectiveness and safety of stenting in all patients younger than 18 years old with coarctation and re-coarctation of aorta which treated by stenting between years 2004-9 at rajaei - heart centre in Tehran, Iran.
Results: we studied 53 patients younger than 18 years old with a follow up of six months. Totally 54 stents were implanted. Mean (±SD) age of the patients was 11.6±4.2yrs. Seventeen cases (32%) were younger than 10 years old, and 36 cases (68%) were 10 years and older. Mean (±SD) weight was 39.24±18kg. 16 cases weighting less than 25kg. Peak systolic pressure gradient (SPG) decreased from 46.26±17.07 to 1.03±0.19mmHg after procedure (p<0.001). There was no significant difference (p<0.001) in the gradient before and after stenting in the patients with native coarctation (Vs re-coarctation cases), less than 25 kg and under 10 years old groups. Complications developed in 44% of cases while dominantly were minor except in two cases re-dilatation of stent was not needed during six month of follow-up of the patients.
Conclusions: Stenting of coarctation of aorta can decrease complications and can be used safely in children weighing bellow 25kg and in children below 10yrs old.
