概括

第三代无支架大动脉假体表现出卓越的长期临床和血液动力学结果,提供良好的耐用性和不受结构性恶化. 这些门非常适合年轻,活跃的患者和那些患有患者假肢不匹配风险的人.

科学领域:

心血管外科心血管外科
生物材料科学生物材料科学
医疗器械医疗器械

背景情况:

严重的大动脉病需要大动脉置换 (AVR) 来恢复心脏功能.
无支柱心周大动脉假体是AVR的先进选择,旨在改善临床结果.
评估第三代无支架门的长期性能对于手术决策至关重要.

研究的目的:

评估AVR的长期临床和血液动力学结果,使用第三代无支架心周假体.
分析与使用这些先进的大动脉门相关的好处和缺点.
为患者选择无支架门植入提供基于证据的建议.

主要方法:

一组548名连续患者在2003年至2015年期间使用第三代无支架心周假肢 (3F®和Pericarbon FreedomTM) 进行AVR.
收集的数据包括患者人口统计,手术细节 (ECC和十字时间),以及早期/住院结果.
长期随访评估了生存率,门功能,结构恶化,内心炎,重新手术和血液动力学表现.

主要成果:

整个队列的早期死亡率为2.55%,孤立AVR的早期死亡率为0.91%. 随访时间中位数为6.77年.
在12年内,心脏存活率为91%,所有幸存者都属于NYHA I级. 没有结构损坏的情况为86%.
在12年内,无内心炎和重新手术的比例为95%,平均残留梯度为10.3mmHg.

结论:

第三代无支架心膜提供了优良的血液动力学和耐用性,在12年内没有结构性恶化.
虽然植入比支架门要求稍高,但它很容易在最少的训练下复制.
这些门推用于年轻,活跃的患者和身体表面积大的人,以避免患者与假肢不匹配.

Mitral Stenosis III: Medical Management

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...

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...
