门节约大动脉根再植入 (VSARR) 提供了有前途的中期结果.
大动脉根直径对长期VSARR结果的影响需要研究.

研究的目的:

评估手术前的大动脉根直径对门节约大动脉根再植入的长期疗效的影响.
在不同的大动脉根直径组中比较包括生存率,复手率和大动脉缺陷在内的结果.

主要方法:

对123名接受大动脉根动脉瘤VSARR治疗的患者的回顾性分析 (不包括A型剖析).
根据手术前的大动脉根直径,患者被分为三个组:>60毫米,50-60毫米和<50毫米.
评估的结果包括死亡率,存活率,无需重新手术,无中度/重度大动脉衰竭.

主要成果:

在直径组中,在术后死亡率,3年生存率或无需重新手术方面没有显著差异.
没有严重/中度大动脉功能不全的情况是相似的,只有四名患者发展出显著的AI.

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

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...
