概括

假肢-患者不匹配 (PPM) 在小型大动脉环 (SAA) 的跨导管大动脉置换 (TAVR) 中很常见. 显著的PPM增加了长期死亡率,突显了SAA TAVR患者需要仔细选择门的需要.

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
人造心脏门是一种假心脏门.

背景情况:

假肢-患者不匹配 (PPM) 是通过导管的大动脉置换 (TAVR) 后的常见并发症.
在患有小主动脉环形 (SAA) 的患者中,PPM尤其令人担忧,可能导致更差的临床结果.
了解SAA TAVR中的PPM对于优化患者管理和改善长期结果至关重要.

研究的目的:

调查针对SAA进行TAVR的患者中PPM的发病率,预测因素和长期临床影响.
为了比较PPM的发生和后果,特别是在SAA TAVR群体内.
确定与PPM相关的因素及其对SAA TAVR后死亡率的影响.

主要方法:

对连续631名SAA患者 (环面积≤430毫米2) 进行 transfemoral TAVR 的回顾性分析.
显著的PPM定义为中度或更大,按门学术研究联盟 (VARC) -3标准分类.
逆概率治疗权重 (IPTW) 用于确定PPM和长期死亡率的预测因素.

主要成果:

在SAA TAVR患者中的23.3%发生了显著的PPM.
预测PPM的预测因素包括生物假体栓塞 (BEV) 植入和更大的身体表面积 (BSA).
显著的PPM独立地与更高的5年死亡率 (HR 1.97) 和中度/高于膜漏洞有关.

结论:

在SAA TAVR人群中,显著的PPM仍然非常普遍.
BEV植入和更大的BSA与PPM风险增加有关,而更大的环形外围显示出保护作用.
显著的PPM是SAA TAVR后长期死亡率的独立预测指标.

关键词:

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...

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...
