概括

接受过导管大动脉置换 (TAVR) 的女性比男性有更好的5年生存率,血液动力学结果相似. 假肢-患者不匹配 (PPM) 仅在男性中影响死亡率,并且在调整并发症后,这种联系消失了.

科学领域:

心血管医学心血管医学
干预心脏病学干预心脏病学
健康结果研究研究结果

背景情况:

在跨导管大动脉置换 (TAVR) 试验中,女性的代表性不足.
女性的解剖学差异可能需要定制的TAVR策略.
这项研究调查了TAVR结果的性别特异性差异.

研究的目的:

评估TAVR的基线特征和程序方法的性别特异性差异.
评估血液动力学结果的性别特异性差异,包括假肢-患者不匹配 (PPM).
确定这些差异对五年全因死亡率的影响.

主要方法:

来自IMPACT TAVR注册表的20094名患者的分析.
根据Valve学术研究联盟-3标准定义的血液动力学结果.
卡普兰-梅尔和考克斯5年死亡率模型;PPM预测因子的逻辑回归.

主要成果:

女性 (49.1%) 年龄较大,症状较强,接受的自扩张更多.
在TAVR后的索引有效孔区域在女性中较大.
在女性中,五年死亡率较低 (HR 0.81). 严重的PPM在女性中较少,仅在男性中与死亡率相关.
通过对两性共同发病率进行调整,PPM与死亡率的关联被取消了.

结论:

这个TAVR队列中的女性比男性有更好的生存率,血液动力学相似.
严重的PPM与男性的死亡率有关,可能是由于并发症.
为混因素进行调整,消除了两性中PPM与死亡率的联系.
TAVR策略应考虑除了假肢血液动力学之外的患者特定风险.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
