Introduction: Congenital heart disease (CHD) is the leading cause of birth defect-associated infant illness and death. In developing countries, the mortality related to CHD increased by up to 25%, but the data about predictors of mortality are limited. The purpose of this study was to investigate the predictors of mortality in neonates with CHD.
Methods: We conducted a case-control study of neonatal mortality with CHD from January 2018 to October 2022. Data were collected from the neonatal registry in Prof Ngoerah Hospital, Bali. Characteristics and clinical risk of mortality were analyzed. Chi-square and logistic regression analysis was carried out to determine the potential predictor of mortality.
Results: A total of 288 neonatal with CHD were analyzed. Neonatal morbidities such as extremely low birth weight (ELBW) were found in 7.6%, asphyxia in 50.7%, multiple congenital anomalies (MCA) in 13.2%, pulmonary hypertension (PH) in 13.5%, sepsis in 66.3%, and severe form of CHD in 50.7%. Patent ductus arteriosus (PDA) was the most acyanotic CHD (35%). Mortality resulting from CHD was 27%. ELBW, severe and moderate asphyxia, MCA, PH, sepsis, and severe form of CHD were significant mortality predictors (p<0.05) with (OR; 95%CI) were (6.21; 1.24-31.12), (4.13; 1.93-8.81), (3.20;1.69-6.08), (2.70; 1.17-6.24), (2.54;1.10-5.84), (2.33; 1.28-4.22), (2.00; 1.15-3.49) respectively.
Conclusion: ELBW, severe and moderate asphyxia, MCA, PH, sepsis, and severe forms of CHD are predictors of neonatal mortality with CHD.
