Maternal and fetal outcome in operated vs non-operated cases of congenital heart disease cases in pregnancy

Abstract

Objectives: To study pregnancy outcomes in operated vs non-operated cases of congenital heart disease cases during pregnancy.

Materials and methods: A total of 55 patients of congenital heart disease who delivered in the authors unit in last 10 years were taken in this retrospective study. These were divided into two groups Group 1:29 (52.7%) patient who had no cardiac surgery and Group 2: 26(47.2%) who had cardiac surgery to correct their cardiac defect before pregnancy. All patients were evaluated for cardiac complications and outcome during pregnancy. Obstetric complications, mode of delivery and fetal outcome was compared in the two groups using statistical analysis.

Result: The commonest lesion was atrial septal defect (ASD) seen in 22(40%) patients followed by ventricular septal defect (VSD) in 16(29%) .Congenital valvular disease 8(14.5%) and patent ductus arteriosus in 4(7.2%) cases. The mean age was 25.9 ± 3.15 years in Group 1 and 26.3 ± 4.53 years in Group 2. The baseline characteristics were similar in the two groups. There was no difference in cardiac complications, NYHA deterioration and need of cardiac drugs in the two groups. Obstetric complications and mode of delivery were also similar in the two groups.Mean birth weight was 2516.65 ± 514.04 gm in Group 1 and 2683.00 ± 366.00 gm in Group 2 and was similar. APGAR < 8, stillbirth rate and other neonatal complications were also similar in two groups.

Conclusion: The maternal and fetal outcome was excellent in patients with congenital heart disease and was similar in unoperated and operated cases.
