OBJECTIVE: We aimed to compare the pulmonary artery (PA) growth between infants with univentricular hearts who underwent a ductus stenting (DS) and those who received a systemic to pulmonary shunt (SPS) as an initial palliation.
METHODS: All infants with ductal-dependent pulmonary blood flow who underwent initial palliation with either a DS or SPS between 2009 and 2022 in our institution were reviewed. PA development was compared between the groups using the PA index and the symmetry index.
RESULTS: A total of 130 patients were evaluated including 49 patients after DS and 81 after SPS. The most frequent primary diagnosis was tricuspid atresia in 27, followed by pulmonary atresia with intact ventricular septum in 19. At stage II palliation, PA index (P = .926), right PA index (P = .692), left PA index (P = .297), and the symmetry index (P = .650) were similar between the groups. At stage III Fontan completion, PA index (P = .115), right PA index (P = .868), and the symmetry index (P = .144) were similar between the groups. However, left PA index (60 vs 74 mm2/m2; P = .015) was lower, and the incidence of venovenous collaterals (24.2% vs 7.8%; P = .036) was higher in the DS group compared with the SPS group. Freedom from PA interventions between stage II and III palliation was lower in the DS group compared with the SPS group (P = .009).
CONCLUSIONS: In infants with univentricular heart after DS, freedom from PA interventions after stage II was lower and the left PA index was smaller, compared with those after SPS. Long-term outcomes after the Fontan procedure should be addressed in patients after DS.
