Abstract
Objective: To determine the outcome of palliative stenting in children with cyanotic congenital heart diseases.
Methodology: From February 2018 to October 2020, the Department of Paediatric Cardiology at Lady Reading Hospital in Peshawar conducted a cross-sectional study on patients who underwent right ventricular outflow tract blocked Blalock Taussig shunt stenting or patent ductus arteriosus stenting for cyanotic congenital heart disease. The patients' information was gathered using a pre-formatted proforma. Pre- and post-procedure oxygen saturations were recorded for 48 hours. The favorable outcome was defined as an increase in oxygen saturation of at least 15%.
Results: The mean age of the sample (n=49) was 20±29 months. The etiology was Pulmonary Atresia (PA) with Patent ductus arteriosus (PDA) in 23 patients, followed by blocked Blalock Taussig Shunt (BT-Shunt) in 9 patients. The number of patients who underwent PDA stenting was 32, 9 patients had stenting of blocked BT-Shunt and 8 patients had RVOT stenting. The mean pre-intervention oxygen saturation was 43% ±8.9% and the mean post-intervention oxygen saturation was 81% ±5.3%. The number of patients who died was 2, one patient for RVOT stenting died on the table due to cyanotic spell while other post-PDA stenting died because of stent thrombosis.
Conclusion: RVOT, Patent Ductus arteriosus, and blocked Blalock Taussig shunt stenting was found effective in increasing oxygen saturation in children with cyanotic PDA.
