33.87mmHg,and 62.24±21.55mmHg in the direct stented patients. Post intervention PG was 20.33 ± 22.5mmHg & 5.64±9.7mmHg in the balloon dilation and direct stent- ing group respectively. However there was no statistical signi cance between the mean pressure gradient di er- ence(42.59mmHg & 54.71mmHg respectively) following intervention in between both arms (P=0.775). Majority showed interventional success n=41(93.2%). Procedural failure was seen n=3(6.3%) of the analyzed populace, of which n=2 belonged to the balloon dilation arm. Majority, n=39(78%) were free of complications.4 patients had com- plications, Aneurysm formation and dissection were each noted at n=1(2%). Only n=10(20%) maintained long term follow up. Of those followed up, mean duration of follow up was 84.8± 56.9months. Most n=9 had preserved EF. Most n=9 showed insigni cant residual PG across CoA .Five remain symptomatic, n=3 complaining of shortness of breath and n=2 complaining of chest pain. Most n=6, had good control of blood pressure. Only 1 patient devel- oped TIA.
Conclusion: Transcatheter intervention in CoA appears to show immediate signi cant successful results, indicating it as an e ective procedure. Balloon dilation alone or direct stent insertion has good immediate outcome, though our study did not show superiority on immediate success. Overall transcatheter management of CoA is a safe proce- dure. Complications though uncommon can be life-threat- ening. Long term residual persistence of symptoms and hypertension necessitate the need for better follow up.

Background: Percutaneous Pulmonary valve implantation is one of the most important inventions of the last century which improves the life quality of a group of patients. Right ventricular out ow tract dysfunction is the fate of operated Tetralogy Fallot, pulmonary atresia, truncus arteriosus, some forms of transposition of the great arteries.
Objective: To share our results and experience of our insti- tution on percutaneous pulmonary valve replacement procedure.
Methods: Between February 2015- September 2017; percu- taneous Pulmonary valve replacement was performed for 10 patients. Balloon interrogation diameters were deter- mined by 34 mm Amplatzer sizing balloons. Andrastent XXL was used for prestenting for all cases. Z-med and BIB balloons were used for stent implantation. They were cho- sen 1 mm larger than the indentation diameter which was measured during interrogation.
Results: Mean age and weight of patient were 12±4.6 years and 38.5±17.6 kg respectively. All the patients were operated for tetralogy of Fallot. All the patients had native, large aneursymatic right ventricular out ow tract (RVOT) dysfunction. Mean balloon interrogation diameter was 22±2.8 mm. Mean diameter of the balloon used for prest- enting was 23±2.3 mm. All the cases except one were replaced with Edwards. Melody valve was used for the one with 19 mm sized balloon interrogation diameter. The procedure was performed successfully for all patients. 29 mm sized Edwards valve was implanted in 4 patients. 23 mm was implanted in 3 patients, 26 mm was implanted in 2 patients, 24 mm was implanted in one patient. Valve implantation of 2 patients was performed with stent implantation in the same session. For the rest of patients pulmonary valve implantation was performed 8-16 weeks after stent implantation. Procedure related mortality was not reported.
Conclusion: Trancatheter pulmonary valve implantation protect the patients from having right ventricle dysfunc- tion. The patients without conduit; prestenting is manda- tory to create a safe landing zone and limit the risk of stent fracture. Percutaneous pulmonary valve implantation is a safe, e ective, non-invasive alternative treatment in RVOT dysfunction. Further experience in children is required therefore new studies with large number of patients should be done.
