概括

通过自扩展 (SE) 或气球可扩展 (BE) 门进行过导管大动脉置换 (TAVR) 显示出类似的左心室缩 (LVH) 回归. 在这项研究中,假肢-患者不匹配 (PPM) 在TAVR后没有显著影响LVH回归.

科学领域:

心脏病学心脏病学
生物医学工程生物医学工程
医疗成像医学成像

背景情况:

有限的数据存在于假肢-患者不匹配 (PPM) 对左心室缩 (LVH) 回归后转管大动脉置换 (TAVR) 的影响.
了解不同类型的假肢对LVH回归的影响对于优化TAVR结果至关重要.

研究的目的:

为了比较超环状,自扩张 (SE) 与内环状,气球可扩展 (BE) 假肢在TAVR后LVH回归的影响.
调查PPM在TAVR后LVH回归中的作用.

主要方法:

对168名TAVR患者 (60 SE, 108 BE) 的追溯评估,进行了基线和随访心声扫描.
左心室质量指数 (LVMi) 在基线和707天的平均随访时间被测量.
在SE和BE组之间,以及按PPM状态进行LVMi回归的比较.

主要成果:

与BE组相比,SE组的有效孔面积指数较高,梯度较低,PPM中度/严重程度较低.
在SE和BE组之间没有观察到绝对或相对LVMi下降的显著差异.
在TAVR患者中,无论PPM状态如何,LVH回归都相似.

结论:

尽管血液动力学参数和PPM有差异,但SE和BE假肢在TAVR后导致类似的LVH回归.
在TAVR后的中期,PPM似乎没有显著影响LVH回归.
进一步的研究可能会探索长期结果和特定的患者子组.

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...
