BACKGROUND: The purpose of this study is to assess the effects of linear and @entity1002 reconstruction on early postoperative outcomes. METHODS: A search of computerized databases supplemented with manual bibliographic review was performed for all peer-reviewed English language publications concerning randomized and nonrandomized studies reporting the results of left ventricular reconstruction after both linear and geometric reconstruction techniques. Meta-analyses of several short-term outcomes were performed. RESULTS: No randomized trial was identified. Eighteen nonrandomized trials were found with a total of 1,814 and 803 @entity1 who underwent linear and geometric reconstruction, respectively. Meta-analysis of all studies (n = 18) revealed an increased risk of in-hospital death for @entity1 undergoing linear reconstruction (relative risk = 1.59, 95% confidence interval: 1.12 to 2.26, p = 0.01). The subanalysis of studies in which linear reconstruction was adopted mainly in the first period of time, and geometric reconstruction was adopted in a later phase, still showed a significant advantage in terms of in-hospital mortality for @entity1 undergoing geometric reconstruction (n = 11 studies, relative risk = 1.89, 95% confidence interval: 1.22 to 2.93, p = 0.004). By contrast, when the two surgical approaches were carried out in the same time lag, there was no difference between linear and geometric reconstruction techniques (n = 7 studies, relative risk = 1.04, 95% confidence interval: 0.57 to 1.92, p = 0.89). No differences in the other outcomes of interest were observed. CONCLUSIONS: The advantage for geometric reconstruction techniques in terms of in-hospital mortality shown in some studies can be an effect of learning curve or of improvement over time in management of these difficult @entity1 . Further studies are required to clarify this issue.
