概述

二叶式主动脉瓣为一种先天性心血管畸形,是胚胎早期动脉干分割为主、肺动脉两大血管后,在瓣叶形成过程中,除发育成正常的3个瓣叶外,也可发育成1个、2个或4个瓣叶,此即瓣叶数目的异常,其发生率为二叶、单叶和四叶递减。二叶主动脉瓣一般呈前后位、左右位或斜位,以前后位多见。其主要发病于男性。主要病因以风湿性退行性改变、及先天畸形,先天性主动脉瓣畸形以二叶式主动脉瓣畸形较常见。分型在分型上根据解剖划分为左、右瓣融合和右冠无冠瓣融合两种,在联合瓣叶的中间可以看到一条表面隆起的嵴线,这条嵴线一直延续至窦壁的

In-hospital mortality of BAV and MVP groups (5.6% and 10.1%, respectively) was significantly lower than that of the high-risk and low/moderate-risk groups, which showed similar mortality rates (29.0% and 28.3%, respectively; both p < 0.01). To further investigate these differences in in-hospital mortality, we analyzed several factors known to be associated with an adverse prognosis in IE. Results of this analysis showed that patients from high-risk and low/ moderate-risk groups were older, had higher comorbidity rates and higher surgical risk, and contracted nosocomial IE and staphylococcal IE more frequently than did patients with BAV and MVP (Table 4). When a propensity score analysis was performed between MVP and BAV individuals and high- and low/ intermediate-risk subjects matched according to age, Charlson index, nosocomial IE, staphylococcal IE, and logEuroSCORE, in-hospital mortality rates between the BAV and MVP groups and the high-risk and low/ moderate-risk groups were not statistically different (Online Tables 4 and 5).

BAV和MVP组的院内死亡率(分别为5.6%和10.1%)明显低于高风险和低/中度风险组,死亡率相似(分别为29.0%和28.3%;均p <0.01)。为了进一步研究院内死亡率的这些差异,我们分析了已知与IE中不良预后相关的几个因素。该分析的结果显示,高风险和低/中等风险组的患者年龄较大,合并症发生率较高,手术风险较高,并且比BAV和MVP患者更频繁地感染了医院IE和葡萄球菌IE(表4) 。当根据年龄,Charlson指数,医院IE,葡萄球菌IE和logEuroSCORE匹配MVP和BAV个体和高和低/中等风险受试者之间的倾向评分分析时,BAV和MVP组之间的院内死亡率并且高风险和低/中等风险组没有统计学差异(在线表4和5)。
