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.
