概括
通过导管的大动脉植入 (TAVI) 与三维通过导管心脏 (THV) 位置并没有预测高节奏负担. 节奏负担没有影响生存,但三分之一的患者在TAVI后3个月内发展出高节奏负担.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 生物医学工程 生物医学工程
背景情况:
- 过导管大动脉植入 (TAVI) 是对大动脉狭窄的常见程序.
- 过导管心脏 (THV) 的位置可能会影响心脏导电.
- 在TAVI后的高节奏负担可能会影响患者的结果.
研究的目的:
- 为了评估三维THV位置对TAVI后中期节奏负载的影响.
- 检查刺激率对TAVI后生存率的影响.
主要方法:
- 对107名患者 (Sapien S3和Evolut R THV) 的分析,使用TAVI前后的CT血管学.
- 融合成像用于确定三维THV位置.
- 在出院前和3个月后评估的节奏刺激率;存活率追踪了5年.
主要成果:
- 在69%的出院前和67%的3个月后观察到高节奏负担 (>20%的刺激).
- 三分之一的患者最初的节奏负担较低,在3个月内发展为高负担.
- 在THV位置,节奏负担和5年生存率之间没有显著的关联.
结论:
- 三维THV位置不能预测TAVI后的高节奏负载.
- 在TAVI后的节奏负担与患者的存活率无关.
- 很大一部分患者在3个月内会增加节奏负担,这表明潜在的导电系统损伤.

Mitral Valve Prolapse I: Introduction
1.1K
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...

Mitral Valve Prolapse II: Assessment and Management
1.4K
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral Valve Prolapse III: Nursing Management
586
The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Mitral Stenosis III: Medical Management
535
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
