概括
最新激活部位的左心室内心节奏是对心力衰竭患者的可行的替代方案,这些患者对传统的心脏再同步治疗没有反应或不符合条件. 然而,这种方法带有更高的并发症风险,需要仔细选择患者.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 心脏衰竭管理的管理
背景情况:
- 传统的心脏再同步治疗 (CRT) 可能对一些心力衰竭 (HF) 患者来说具有挑战性.
- 对于CRT无响应者或那些有植入困难的人,需要使用替代的植入策略.
研究的目的:
- 评估左心室 (LV) 内心节奏在最新的激活部位的可行性,疗效,并发症和长期结果.
- 评估这项技术在具有具有挑战性的CRT植入或不响应的HF患者中.
主要方法:
- 对11名患有扩张性心肌病的患者进行了回顾性分析,这些患者接受了LV内心节律调节.
- 通过穿越性穿刺进行3D映射指导的程序,以准最新的LV激活部位.
主要成果:
- 63.6%的患者表现出临床改善 (例如,NYHA类).
- 并发症包括口袋血液瘤,感染和血栓栓塞事件 (总体27.3%).
- 估计1,3年和5年死亡率分别为9.1%,18.2%和27.3%.
结论:
- 在最新的激活部位进行LV内心节律调节是选择可接受CRT患者的可行替代方案.
- 这种手术的并发症率相对较高,需要仔细选择患者,并可能提供终身抗凝药.

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

52
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
