CONCLUSION
Though a rare congenital cardiac anomaly, presentation of the aortopulmonary window in the adolescent age group is observed among developing countries. Irreversible pulmonary artery hypertension precludes closure of the defect. Device closure is restricted for intermediate types with adequate superior and inferior rims. Surgical closure can be safely achieved for reversible pulmonary hypertension cases with excellent long-term outcomes. However, given the low prevalence of extrinsic compression of the LMCA due to PAH, a large multicentre trial is needed to identify the optimal treatment.
