概括

在跨导管大动脉置换 (TAVR) 中,对自扩张的跨导管心脏 (THV) 进行最佳尺寸定位至关重要. 较低的超大尺寸 (≤14%) 改善了TAVR患者的技术成功和减少了并发症.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗器械医疗器械

背景情况:

准确的门尺寸对于成功的跨导管大动脉置换 (TAVR) 和跨导管心脏门 (THV) 的长期耐用性至关重要.
对于自我扩展 (SE) 的年内THV的最佳尺寸策略仍然是积极调查的领域.

研究的目的:

评估假肢超大尺寸对接受TAVR的患者手术和临床结果的影响.
具体评估Portico和Navitor SE年度内THV的结果.

主要方法:

400名接受TAVR的患者与SE年内THV进行了回顾性多中心研究 (2017年10月至2024年9月).
根据中位数 (14%) 的超大小,患者被分为低 (≤14%) 和高 (>14%) 的超大小组.
主要终点:技术成功;次要终点:30天设备成功,心脏起器植入,死亡率,住院,门功能障碍.

主要成果:

在低超大化群体中,技术成功率更高 (96.7%对92.1%,p=0.048).
栓栓塞仅发生在高超大小组 (2.1%,p=0.035) 中.
两组之间30天设备的成功率,膜回率或心脏起器植入率没有显著差异.

结论:

在TAVR与SE年内THV的低超大小 (≤14%) 与更好的技术成功有关.
这一策略还与减少门相关并发症,如栓塞等相关.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
