概括

大动脉置换后的假肢患者不匹配 (PPM) 可能导致心脏功能障碍并增加死亡率. 手术大动脉根扩大 (ARE) 是通过增加大动脉根大小来预防PPM的一种安全方法.

科学领域:

心脏外科手术心脏外科手术
心血管医学心血管医学
生物医学工程生物医学工程

背景情况:

假肢-患者不匹配 (PPM) 发生在一个大动脉假肢对患者来说太小时.
PPM导致过高的膜梯度,左心室功能障碍,增加发病率和死亡率.
年轻患者和手术前左心室功能障碍患者特别容易受到伤害.

研究的目的:

审查大动脉置换中假肢-患者不匹配 (PPM) 的定义,后果和预防策略.
讨论大动脉根扩大 (ARE) 的手术技术,以预防PPM.

主要方法:

审查现有的关于假肢-患者不匹配 (PPM) 和大动脉根扩大 (ARE) 技术的文献.
讨论用于有效孔径面积 (EOA) 测量的回声心脏学方法.
分析既定和当代的ARE程序.

主要成果:

在体内回声心脏图是确定预测有效孔径面积 (EOA) 的最可靠方法.
手术性大动脉根扩大 (ARE) 技术,包括尼克斯,曼努圭安,科诺-拉斯坦和手术,可以有效地解决PPM.
手术显示出安全增加大动脉根大小2到3个大小的前途.

结论:

大动脉根扩大 (ARE) 是一种有价值和安全的手术策略,用于防止假肢-患者不匹配 (PPM).
在患有PPM风险的患者的手术规划中,应考虑ARE.
有效预防PPM可以改善大动脉置换后的长期结果.

Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

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...
