摘要
BackgroundValve-sparing aortic root replacement (VSARR) is a safe and effective surgical procedure to treat aortic root aneurysm. This meta-analysis aimed to investigate how this procedure might differ in patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV).DesignMeta-analysis with meta-regression and systematic review.SettingSystematic search in the following databases: PubMed, Cochrane Central Register of Controlled Trials, and Embase.InterventionsAll observational studies of VSARR in patients with BAV or TAV were included in our study. Studies were included without any restrictions on language or publication date. A trial sequential analysis and a post-hoc meta-regression was performed on the main outcomes.ResultEleven articles met the inclusion criteria. A total of 1138 patients in BAV group, and 2125 patients in TAV group. No significant differences in gender and age were observed between BAV and TAV patients. BAV and TAV patients showed no differences in in-hospital mortality rate [0.00% vs. 1.93%; RR (95% CI) 0.33 (0.09, 1.26), I-2 = 0%, P = 0.11] and the rate of in-hospital reoperation [5.64% vs. 5.99%; RR (95% CI) 1.01(0.59, 1.73), I-2 = 33%, P = 0.98]. The overall long-term mortality rate of BAV patients was better than that of TAV patients [1.63% vs. 8.15%; RR (95% CI) 0.34 (0.13, 0.86), I-2 = 0%, P = 0.02]. During the follow-up observation period, patients in TAV group showed small but no statistic advantage in 3-year, 5-year, and over 10-year incidences of reintervention. Regarding the secondary endpoints, the two groups showed similar aortic cross-clamping time and total cardiopulmonary bypass time.ConclusionThe VSARR techniques yielded similar clinical outcomes in both BAV and TAV patients. Although patients with BAV might have a higher incidence of reinterventions after initial VSARR, it is still a safe and effective approach to treat aortic root dilation with or without aortic valve insufficiency. TAV patients showed small but no statistic advantage in long-term (over 10 years) reintervention rate, which means, patients with BAV may face a higher risk of reintervention in the clinic.
