Cardiac Surgery with Cardiopulmonary Bypass in Low-Weight or Preterm Neonates:A Retrospective Study Analyzing Early Outcome

Background:Most outcome studies in congenital cardiac surgery for“low weight”neonates include patients undergoing surgery without cardiopulmonary bypass(CPB).The primary objective of our study was to identify risk factors for in-hospital mortality in neonates weighing less than 3 Kg and undergoing surgery with *** addition,we compared the effect of early surgery with CPB(before 37W-gestational age(GA))for congenital heart disease to delayed surgery until a corrected GA of 37 weeks in an attempt to promote weight ***:Retrospective single-center study including all patients operated between 1997 and ***-and multivariable analysis were used to analyze ***:143 patients were *** median weight was 2.7 Kg and 49(34.3%)weighted<2.5 Kg.80%of the patients were Risk stratification STAT categories≥3.114 patients(80%)were operated without delay(usual timing,median age 9 days),whereas 29 patients(20%)entered a delayed strategy(median age 30 days).In-hospital mortality was 21.7%.By multivariate analysis,dysmaturity,preoperative positive ventilation,post-operative ECMO requirement or resuscitation,and any residual lesion were predictors of in-hospital ***-hospital mortality in the usual timing group and the delayed group were 21.1%and 24.1%,respectively(p=0.71).In-hospital mortality for neonates operated prior to 37W-GA(n=10)was 27.3%.Conclusions:Predictors of in-hospital mortality in neonates less 3 Kg requiring CPB surgery did not differ from those unveiled in other contemporary *** data demonstrates that a strategy of delaying surgery in selected patients resulted in similar clinical outcome.
