INTRODUCTION Incidence of congenital heart disease is 25 per thousand live birth in Bangladesh which is much higher than other countries. Tetralogy of Fallot, the commonest cyanotic heart disease (5%) and some other complex diseases with right ventricular outflow tract abnormality demand surgical correction and revision in many occasions including percutaneous intervention. As a resource constraint country, it was a difficult task to introduce percutaneous pulmonary valve implantation (PPVI) with MelodyTM. However, it was started on 12th December 2012 in Combined Military Hospital Dhaka, Bangladesh and cases performed till October 2019 were included in this series. METHODS Retrospective analysis of six cases who had PPVI with MelodyTM in Combined Military Hospital, Bangladesh. Patient with dysfunctional conduit between right ventricle (RV) and pulmonary artery causing (a) Symptoms of exceptional dyspnoea of various grade (NYHA II,III, IV) (b) RVEVD >150 ml/m2 ±regurgitant fraction >40% (c) RVOT peak instantaneous gradient > 30 mm Hg. (d) RV dysfunction (RVEF<40%) were accepted for the procedure and outcome were analyzed. RESULTS Mean age was 9.56 ± 2.96 years, weight was 28.75 ± 8.61 kg, height was 137.5 ± 17.52 cm. Mean age at surgery was 4.25 ± 2.72 years. Female were 66.66%. Aortic homograft was used in 66.66% cases. Eighteen mm Ensemble was used in four (66.66%) cases and 20 mm and 22 mm in one each. Immediate result was excellent with no residual PS in two cases and negligible residual flow acceleration across pulmonary valve in four cases. No PR seen in all except one. One patient developed Bacterial endocarditis after 3 years and was treated. CONCLUSION Aim of PPVI is to prolong the life expectancy of conduits which were placed surgically from right ventricle to pulmonary artery. In our case series, we found that Melody valve is functioning well without any complications like infective endocarditis or stent fracture. KEYWORDS PPVI, MelodyTM, RVOT, Outcome
