Abstract

Objective: We reviewed our centerís prenatal detection and surgical experience with high-risk, 2-ventricle patients, with complex congenital heart disease that underwent stage-1 hybrid palliation. Methods: We retrospectively identified those born between March 2008 and March 2021 with 2-ventricle hearts, complex congenital cardiovascular malformations, and ductal-dependent systemic circulation that underwent stage-1 hybrid palliation consisting of surgical bilateral pulmonary artery banding and interventional catheterization placed ductus arteriosus stents.

 

Results: We identified 30 patients. Of the 30, 19 (63%) were male. For the 30, median gestational age was 35 weeks (29-39 weeks), and median birth weight was 2.2 kg (0.6-4.5 kg). Of the 30, 1 was transferred from an adjacent state, and 29 were born in Nevada. Of the 29 born in Nevada, overall statewide prenatal detection was 18 of 29 (62%); however, for 2008 to 2011 the prenatal detection rate was 3 of 10 (30%) and 15 of 19 (79%) for 2012 to 2021, P = .03. For the last 5 years, prenatal detection for Nevada-born patients was 8 of 8 (100%). Two full-term newborns, without a prenatal diagnosis, presented postnatally in extremis. For the 30 patients, there were 0 stage-1 hybrid palliation mortalities, 1 subsequent repair mortality, and 3 late nonsurgical deaths.

 

Conclusions: Stage-1 hybrid palliation may result in excellent surgical outcomes for high-risk, 2-ventricle patients. Additionally, high rates of population-wide prenatal detection are possible for high-risk congenital heart disease, allowing prenatal planning and possibly reducing postnatal extremis presentations.
