概括

对于功能性 mitrale regurgitation (FMR) 的跨导管端到端修复 (TEER) 后,后负载不匹配 (AM) 会增加住院死亡率,但不会增加长期存活率. 相称的MR是一种危险因素,而levosimendan和furosemide具有保护作用.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心脏衰竭管理的管理

背景情况:

在左心室喷射分数 (LVEF) 减少的患者中,对于严重的功能性 mitrale regurgitation (FMR) 进行过导管边缘到边缘修复 (TEER) 可能会导致后负载不匹配 (AM).
后负荷不匹配 (AM) 是TEER后的左心室后负荷急剧增加.
这项研究旨在定义AM,确定其决定因素,并评估其在FMR患者TEER后的预后影响.

研究的目的:

在跨导管边缘到边缘修复 (TEER) 的背景下,从临床上重新定义后负载不匹配 (AM).
分析TEER后AM的临床决定因素.
评估AM对FMR患者的住院和长期死亡率的预后意义,LVEF ≤35%.

主要方法:

一项多中心病例控制研究,涉及FMR患者,LVEF ≤35%接受TEER.
后负载不匹配 (AM) 被定义为在TEER后24小时内急需无otropic或机械循环支持升级的急性需求.
68例AM病例的倾向与68名对照患者相匹配;主要终点是住院和2年全因死亡率.

主要成果:

对于TEER的程序成功率很高 (92%).
相称的额头回 (MR) 与AM风险增加有关 (adj-HR 1.6).
使用levosimendan (adj-HR 0.29) 和更高剂量的furosemide进行预治疗,对AM有保护作用. 在AM队列中,住院死亡率较高 (10%对2%),但2年死亡率相似 (34%对20%).

结论:

在低LVEF的FMR患者中,TEER后的后负载不匹配 (AM) 与增加的住院死亡率有关.
AM并没有显著影响2年全因死亡率.
相对的MR是AM的风险因素,而levosimendan和furosemide提供保护作用.

Mitral Regurgitation I: Introduction

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Regurgitation III: Medical Management

Mitral Regurgitation III: Medical Management

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
