概括

对于经过跨导管大动脉置换 (TAVR) 并且有边界大动脉环大小 (BAAS) 的患者,过度扩张门 (OE-THV) 显示了与常规大小测量相似的结果. 在不增加重大并发症的情况下,OE-THV可能会减少起器需求.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
生物医学工程生物医学工程

背景情况:

在接受过导管大动脉置换 (TAVR) 的患者中,很大一部分患者有边界大动脉环大小 (BAAS).
过度扩张一个小尺寸的气球可扩展透气管心脏门 (BE-THV) 是一种探索的策略,以减轻这些患者的风险.
潜在的好处包括减少电气干扰和环状损伤,但可能会增加像膜漏洞 (PVL) 这样的风险.

研究的目的:

为了比较传统的THV大小测定与超大规模THV (OE-THV) 在BAAS患者的超大规模THV (OE-THV) 的结果.
审查现有文献,并对这个特定的患者亚组进行元分析.

主要方法:

对9项非随机研究的数据进行了元分析.
研究将传统的THV大小策略与BAAS患者的OE-THV策略进行了比较.
文献审查的重点是BE-THV在BAAS病例中的使用.

主要成果:

两种策略之间没有观察到死亡率,中风,平均梯度或显著的膜漏洞 (PVL) 的显著差异.
在OE-THV组中,人们注意到了减少心脏起器植入的趋势.
这些发现表明,BAAS的传统尺寸和OE-THV之间的平衡.

结论:

边界大动脉环大小是TAVR患者的常见发现.
目前的证据表明,传统大小和OE-THV策略之间的重大不良事件没有显著差异.
需要进一步的研究,以充分阐明这些方法的短期和长期结果.

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 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...
