Outcomes After Aortopulmonary Window for Hypoplastic Pulmonary Arteries and Dual-Supply Collaterals. Bauser-Heaton, H., Ma, M., McElhinney, D. B., Goodyer, W. R., Zhang, Y., Chan, F. P., Asija, R., Shek, J., Wise-Faberowski, L., & Hanley, F. L. The Annals of Thoracic Surgery, 108(3):820–827, 2019. doi abstract bibtex BACKGROUND: Our institutional approach to tetralogy of Fallot with major aortopulmonary collateral arteries (MAPCAs) emphasizes early unifocalization and complete repair (CR). In the small subset of patients with dual-supply MAPCAs and confluent but hypoplastic central pulmonary arteries (PAs), our surgical approach is early creation of an aortopulmonary window (APW) to promote PA growth. Factors associated with successful progression to CR and mid-term outcomes have not been assessed. METHODS: Clinical data were reviewed. PA diameters were measured offline from angiograms prior to APW and on follow-up catheterization \textgreater1 month after APW but prior to any additional surgical interventions. RESULTS: From November 2001 to March 2018, 352 patients with tetralogy of Fallot/MAPCAs underwent initial surgery at our center, 40 of whom had a simple APW with or without ligation of MAPCAs as the first procedure (median age, 1.4 months). All PA diameters increased significantly on follow-up angiography. Ultimately, 35 patients underwent CR after APW. Nine of these patients (26%) underwent intermediate palliative operation between 5 and 39 months (median, 8 months) after APW. There were no early deaths. The cumulative incidence of CR was 65% 1 year post-APW and 87% at 3 years. Repaired patients were followed for a median of 4.2 years after repair; the median PA:aortic pressure ratio was 0.39 (range, 0.22 to 0.74). CONCLUSIONS: Most patients with tetralogy of Fallot/MAPCAs and hypoplastic but normally arborizing PAs and dual-supply MAPCAs are able to undergo CR with low right ventricular pressure after APW early in life. Long-term outcomes were good, with acceptable PA pressures in most patients.
