ABSTRACT

Introduction: The incidence of congenital heart diseases (CHD) is 6 per 1,000 live births. CHD frequently increases the risk of early death. Surgical correction may improve the survival rate and clinical prognosis. The main objective of this study is to estimate the 1-year survival rate after surgical correction in children born with CHD.
Methods: This a cross-sectional design on 127 consecutive pediatric patients with CHD surgically corrected, between January, 2006 and December, 2010 in a referral pediatric hospital of Sonora, Mexico. The 1-year survival rate and the early mortality rate (≤ 30 days) were estimated. A bivariate analysis was carried out to describe potential differences in clinical and sociodemographic features. The differences were assessed by X2 and ANOVA test. A logistic bivariate analysis was done to examine the relation between survival and clinical characteristics.
Results: The 1-year survival rate after surgical correction was 44%; while the early mortality rate was 24%. Corrective surgery improves the1-year survival rate, OR = 6.8, 95% CI(2.8, 16.7).
Discussion: The 1-year survival rate after surgical correction of CHD is lower than other reports.Associated with this low survival rate, the early death rate is higher than previous studies. One factor that improves the probability of survival is to perform early surgical correction, which may depend on the underlying CHD and an earlier diagnosis of the condition.
