概括

手术性大动脉置换 (SAVR) 显示出更好的长期结果和左心室质量回归,而不是跨导管大动脉置换 (TAVR). TAVR提供了较小的压力梯度和更大的门面积后过程.

科学领域:

心血管外科心血管外科
干预心脏病学干预心脏病学
心脏成像 - - 心脏成像

背景情况:

有限的数据存在于手术后的左心室质量 (LVM),大动脉面积 (AVA) 和日本SAVR和TAVR后的压力梯度 (PG).
这项研究通过比较这些参数和在一个日本中心的SAVR和TAVR患者之间的长期结果来弥补这一差距.

研究的目的:

为了比较术后的LVM,AVA,中风体积 (SV),PG和SAVR和TAVR之间的长期结果.
为了解这些大动脉置换策略在日本人口中的比较有效性提供见解.

主要方法:

追溯队列研究包括107名SAVR患者和274名TAVR患者.
随访期平均为28.8个月,中位数为24个月.
分析重点是心声回声学参数和临床结果,包括死亡率,再住院和MACCEs.

主要成果:

与SAVR相比,TAVR组的PG平均值明显较低,AVA指数较大.
在程序后,SAVR组显示LVM指数和SV指数明显较小.
在TAVR组中观察到较高的副膜泄漏率和心脏起器植入率.
SAVR组的5年生存率明显提高,再入院减少,MACCE减少.

结论:

手术后的血液动力学 (PG,AVA,SV) 支持TAVR,而左心室质量回归和长期临床结果优于SAVR.
这些发现表明,SAVR与TAVR之间的急性血液动力学益处和长期临床结果之间的权衡.

关键词:

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

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...
