概括

在严重心肌病患者中,心室动脉冲动 (VT) 移除具有高风险,经常复发和死亡. 延迟增强心磁共振成像 (DE-CMR) 有助于定位VT起源,尽管心脏重塑显著.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
心脏成像 - - 心脏成像

背景情况:

对于结构性心脏病患者来说,心室动脉冲动 (VT) 移除是至关重要的.
在没有LVAD的情况下,在非常严重的心肌病中静脉瘤切除的特征还不清楚.

研究的目的:

分析静脉管切除的手术和成像特征,在严重减少喷射分数 (EF <20%) 和没有LVAD的患者中.
评估一个复合的结果,即没有静脉瘤,LVAD或移植的生存.

主要方法:

包括连续患有EF<20%且没有LVAD进行静脉管切除的患者.
评估的程序数据,DE-CMR发现和复合的临床结果.

主要成果:

27名患有严重心肌病的患者 (EF 12.8%) 进行了切除.
在93%的患者中,DE-CMR发现了痕,在82%的患者中定位了静脉瘤的起源.
中期随访显示VT复发率高 (56%),死亡率高 (30%) 和复合结局高 (82%).

结论:

在非常严重的心肌病中进行静脉管切除是一种高风险的手术,中期结果不佳.
DE-CMR对于识别静脉瘤基质和起源,甚至在晚期心脏病中也是有价值的.

Disturbances in Heart Rhythm

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...
