Abstract

Objective: To evaluate the birth outcomes and maternal variables of cases with different types of left-sided obstructive defects (LSOD) of the heart. Methods: Live-born infants were selected from the population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, and 302 cases with LSOD, 469 matched controls and 38,151 all controls without any defect, and 20,750 malformed controls with other isolated defects were compared. The diagnosis of LSOD was based on autopsy report or the documents of surgical intervention. Results: Four types of LSOD were differentiated: 56 cases with valvular aortic stenosis (VAS), 76 cases with hypoplastic left heart syndrome (HLHS), 113 cases with coarctation of the aorta (COA) and 57 cases with other congenital abnormalities of aorta (OCA). Cases with LSOD had male excess (64.6%) with a higher rate of preterm birth (14.2 vs. 6.6%) and low birthweight (15.6 vs. 4.3%) compared to matched controls. The high rate of preterm birth was particularly characteristic for HLHS (17.1%) while intrauterine fetal growth restriction was found in cases OCA (22.8%) and COA (13.3%). The mothers of cases with LSOD had higher birth order and lower socio-economic status than controls without any defect. Conclusions: The general pattern of birth outcomes and maternal variables were similar in the types of LSOD cases, but the higher rate of preterm birth and low birthweight indicated some association with their adverse fetal development.
