概括
跨导管大动脉置换 (TAVR) 后新出现的右束枝阻塞 (RBBB) 显著增加了永久心脏起器植入 (PPI) 的风险. 这一发现凸显了对TAVR后RBBB的监测的重要性.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 心脏电生理学 心脏电生理学
背景情况:
- 延迟和复发的完整心房静脉阻塞 (CAVB) 是通过导管的大动脉置换 (TAVR) 后的一种严重并发症.
- 预测CAVB和TAVR后需要永久心脏起器植入 (PPI) 对于患者管理至关重要.
- 在TAVR之后,新出现的右捆分支区块 (RBBB) 和PPI之间的关联尚未得到充分理解.
研究的目的:
- 调查新发束分支区块 (BBB),特别是RBBB对TAVR后永久心脏起器植入 (PPI) 的要求的影响.
- 在接受TAVR的患者中确定PPI的预测因子.
主要方法:
- 对407名患有大动脉狭窄症的患者进行了TAVR的分析.
- 在基线,TAVR后立即,以及在术后第1天和第5天对12心电图的评估,以检测新发的BBB和CAVB.
- 多变量逻辑回归用于确定PPI的预测因子.
主要成果:
- 40名患者 (9.8%) 需要PPI,其中23名 (5.7%) 经历了延迟或复发的CAVB.
- 新发起的RBBB发生在4.7%的患者中.
- 与没有BBB (3.4%) 或新发左BBB (5.6%) (P<0.0001) 的患者相比,新发RBBB的患者的PPI率 (44.4%) 显著更高 (P<0.0001).
- 新发的RBBB是PPI (OR,18.0) 的重要预测因子,独立于持续的手术内CAVB,以及使用自扩张 (OR,2.97).
结论:
- 在TAVR之后新出现的RBBB是永久心脏起器植入的高风险的强有力的指标.
- 密切监测和风险分层对于患有TAVR后RBBB的患者至关重要.

Cardiac Catheterization II: Right Heart Catheterization
2.2K
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Cardiomyopathy II: Dilated Cardiomyopathy
790
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,...

Cardiomyopathy V: Interprofessional Care
753
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...
