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%)weightedstratification 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.

本过程使用标准原料——硝酸溶液和气氨生产硝酸铵,它可明显地划分为二个操作阶段。第一操作阶段是硝酸与氨的中和反应,它是在恒高于溶液蒸汽压的操作压力下,于高循环流动反应回路中进行。因此,不产生工艺蒸汽,所有反应热蓄积在循环溶液中,标志为溶液温度升高。反应回路的温度由间接热交换器来控制。第二操作阶段是溶液的逐级浓缩。第一

磁共振成像评估先天性左心室室壁瘤的作用

引用

世界核心医学期刊文摘（心脏病学分册） 2007年第11期3卷 33-34页

作者： McMahon C.J. moniotte S. Powell A.J. T. Geva 徐永城 Department of Cardiology Children's Hospital Boston Boston MA United States Dr.

先天性左心室(LV)室壁瘤是一种病因未明的罕见畸形,且通常预后很差。本研究的目的为评价心脏磁共振成像对先天性LV室壁瘤患者的评估作用,并确定室壁瘤的临床表现与形态学特征及功能特征的关系。在26例连续的先天性LV室壁瘤患者中。
