概括
永久性起器植入 (PPI) 是通过导管的大动脉植入 (TAVI) 后的常见并发症. 大约36%的患者需要在12个月内永久依赖心脏起器 (PD),根据基线QRS持续时间和导电障碍预测.
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:
- 永久心脏起器植入 (PPI) 是一个已知的并发症,继过导管大动脉植入 (TAVI).
- 在TAVI后的长期心脏起器依赖 (PD) 需要进一步调查以了解其患病率和预测因素.
研究的目的:
- 为了确定TAVI后PD的患病率.
- 为了确定与PD相关的患者特征.
- 为了阐明TAVI之后的PD预测因素.
主要方法:
- 连续在一个中心接受TAVI的患者的分析.
- 包括376名患者,详细的人口统计和程序数据.
- 在12个月后评估PPI率和PD,并分析基线和程序后变量.
主要成果:
- 18%的患者 (69/376) 在TAVI后接受了PPI;其中36% (21/59) 在12个月后发展为PD.
- 预测PD的预测因素包括更长的基线QRS持续时间,右捆分支阻塞和早期开始的完整心房阻塞.
- 患有PD的患者在12个月后表现出更低的自发心率和更高的心室节奏百分比.
结论:
- 在TAVI之后,PPI很常见,很大一部分人患有长期PD.
- 基线QRS持续时间,先前存在的右捆分支阻断和早期完整的AV阻断是PD的关键预测因素.
- 识别这些预测因素可以帮助对接受TAVI的患者进行风险分层和管理.

Aortic Regurgitation I: Introduction
456
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

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...

Mitral Valve Prolapse I: Introduction
363
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
