概括
预先存在的双纤膜阻塞,更深的隔膜植入和新的捆绑分支阻塞预测在门内透管大动脉置换 (ViV-TAVR) 后需要永久心脏起器植入 (PPI). 大动脉反可能会降低PPI风险.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 心脏外科手术 心脏外科手术
背景情况:
- 门内透管大动脉置换 (ViV-TAVR) 是对退化大动脉的日益增长的手术.
- 在TAVR后永久心脏起器植入 (PPI) 会增加患者的发病率和死亡率.
- 对于特别在ViV-TAVR后的PPI的预测因素尚未得到充分确立.
研究的目的:
- 确定在接受ViV-TAVR的患者中预测需要PPI的临床和程序因素.
- 改善ViV-TAVR程序的风险分层和程序规划.
主要方法:
- 对261名连续ViV-TAVR患者 (2012-2022) 的回顾性观察研究.
- 对临床,心电图,手术和光镜数据的分析.
- 倾向性得分匹配和多变量逻辑回归来识别PPI预测因素.
主要成果:
- 9.2%的患者 (24/261) 需要PPI.
- 预测PPI的预测因素包括手术前的双筋阻塞,更大的隔膜植入深度,以及手术后的新左或右捆枝阻塞.
- 作为门衰竭的原因,大动脉反与PPI的几率较低有关.
结论:
- 双筋阻塞,增加隔膜深度和新的捆绑分支阻塞是ViV-TAVR后PPI的关键预测因素.
- 大动脉反可能会对PPI有保护作用.
- 对于接受ViV-TAVR的患者来说,谨慎的风险分层和程序规划是必不可少的.

01:30Cardiomyopathy II: Dilated Cardiomyopathy
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,...

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...
