概括

在TAVI后预测心脏起器植入至关重要. 左心室外流通道 (LVOT) 的形态显著增加了Evolut门手术后永久起器 (PPM) 植入的需要.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心脏成像 - - 心脏成像

背景情况:

预测穿通管大动脉植入后的永久起器植入 (PPM) 对于程序规划和患者咨询至关重要.
左心室外流管 (LVOT) 形态是影响TAVI后传导障碍的潜在因素.

研究的目的:

为了评估LVOT形态,特别是一个渐变的配置,预测导电干扰需要PPM后TAVI使用Evolut自膨胀.
用Evolut系统在接受TAVI的患者中识别PPM的预测因素.

主要方法:

对189名接受TAVI治疗的患者进行了回顾性多中心研究,使用了Evolut自扩张.
在TAVI前的多切片计算机断层扫描 (MSCT) 分析LVOT形状,膜隔膜 (MSep) 长度和着陆区化.
在最终的动脉造影中测量植入深度 (ID).

主要成果:

17名患者 (9%) 在30天后需要PPM.
渐变的LVOT配置与三倍高的PPM率 (21%对7%,p=0.015) 相关.
PPM的独立预测因素包括缩的LVOT (OR:4.2),先前存在的右束分支区块 (RBBB) (OR:12.4),以及具有短MSep的深植入 (OR:16.4).

结论:

渐变的LVOT形态,先前存在的RBBB和具有短MSep的深层植入是Evolut TAVI后PPM的独立预测因素.
将LVOT配置和MSep长度集成到程序前规划中可能会提高患者选择和PPM预测.
这些发现有助于优化TAVI程序规划和患者管理.

关键词:

Heart Valves

Heart Valves

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

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...
