概括

透导管三门置换 (TTVR) 可以影响心脏植入式电子设备 (CIED) 导致31%的患者. 大多数变化是轻微的,并保守地管理,但有些需要干预.

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:

跨导管三管替换 (TTVR) 越来越多地用于严重的三管吐.
接受TTVR治疗的患者往往已经有心脏植入式电子设备 (CIED).
对于TTVR对CIED完整性和功能的影响仍然不完全理解.

研究的目的:

为了评估TTVR使用EVOQUE门系统对CIED领先功能的影响.
评估TTVR后节奏值,传感和阻抗的变化.
在TTVR期间识别与CIED相关的潜在并发症.

主要方法:

在梅奥诊所罗切斯特进行了回顾性观察性研究.
包括32名连续患有先前存在的CIED的患者,他们使用EVOQUE系统进行了TTVR.
在TTVR之前和之后分析CIED领先参数 (速度值,传感,阻抗).

主要成果:

31%的患者 (10/32) 在TTVR后经历了功能变化.
右心室导管最常受到影响.
感应R波变化是最常见的变化 (55%的受影响病例),通常是孤立的,并保守地管理.
13%的患者 (4/32) 显示有关绝缘断裂的发现,其中一个需要进行修改.
两名患者 (40%的随访时间>600天) 呈现逐渐阻抗下降,这表明潜在的亚临床降解.

结论:

使用EVOQUE系统的TTVR与31%的CIED患者的功能变化有关.
大多数与有关的变化是可以保守地管理的,但由于隔热破坏的担忧,一个子集需要干预.
需要进一步的研究,以优化在TTVR期间对设备-相互作用的植入技术和管理策略.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
