Abstract

Background: Ductal-dependent cyanotic newborns require a secure source of pulmonary blood flow. There has been a recent migration to selective ductal (patent ductus arteriosus [PDA]) stenting for some of these children. Universal (nonselective) ductal stenting for all infants with ductal-dependent pulmonary blood flow is controversial. We examine outcomes from a single center with this practice change. Methods: We compare outcomes of all ductal-dependent pulmonary blood flow infants (2013-2020 [January-June]) in the following treatment eras: Era 1 (selective PDA stenting; 2013-2017) or Era 2 (universal PDA stenting; 2018-2020 [January-June]). Results: Eighty-eight patients (Blalock-Taussig shunt, n=41; PDA stent, n=47) met inclusion criteria. In Era 1, most received Blalock-Taussig shunt (62% [41/66]). In Era 2, all received PDA stents (100% [22/22]). There were more females in Era 2, but otherwise no demographic differences between eras. There were no differences in mortality, treatment failures, complications, or reinterventions between eras. Postprocedure length of stay was shorter in Era 2 (8 versus 22 days, P=0.02). There were less surgical revisions for PDA stent patients (2% versus 20%, P=0.02). Postprocedure recovery surrogate end points favored Era 2 and PDA stenting. Additional analysis revealed PDA stent (compared with Blalock-Taussig shunt) patients had shorter post-procedure (10 versus 29 days, P≤0.001) length of stay and more symmetrical branch pulmonary arteries (0.9 versus 0.7, P=0.001) at subsequent surgery. Conclusions: PDA stenting for almost all ductal dependent cyanotic newborns can be safe and effective and may have lower morbidity than selective PDA stenting.
