概括

通过导管的大动脉植入 (TAVI) 与心肺旁路 (CPB) 在患者之前的额头假体可能是安全的. 仔细的患者选择和监测对于成功的TAVI手术至关重要.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心脏外科手术心脏外科手术

背景情况:

过导管大动脉植入 (TAVI) 很少在患有现有 mitra 假肢的患者中进行.
大动脉跨导管的安置试验排除了先前进行过中枢干预的患者.
在这个人群中,TAVI期间的血液动力稳定性可以通过心肺绕道 (CPB) 实现.

研究的目的:

描述 transfemoral TAVI 的可行性和结果,在患有先前存在的生物假体中枢的患者中.
在复杂病例中突出骨-骨CPB在TAVI期间管理血液动力学稳定的作用.

主要方法:

一个90岁的女性患者的病例报告,患有严重的大动脉狭窄和生物假体关节.
紧急气球膜整形,然后进行可选的膜移植TAVI.
在TAVI期间利用正常热的股骨-股骨心肺绕道进行血液动力学支持.

主要成果:

通过使用股骨-股骨CPB进行了成功的股骨转移TAVI.
在TAVI后,左心室喷射率改善到63%.
在手术后没有观察到显著的 mitra 回或狭窄.

结论:

使用CPB的TAVI可以安全地在老年患者中进行,这些老年患者之前已经有过米特拉假肢.
对CPB的外周管插入具有重大风险,需要仔细考虑.
需要进一步验证,以评估TAVI与CPB的安全性,因为可能会侵入组织.

Mitral Stenosis III: Medical Management

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...

Mitral Valve Prolapse II: Assessment and Management

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 I: Introduction

Mitral Valve Prolapse I: Introduction

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...
