心脏外科手术心脏外科手术
干预心脏病学干预心脏病学

背景情况:

严重的性大动脉狭窄症 (AS) 在外科大动脉置换 (SAVR) 中带来了重大挑战,特别是在大动脉环结石化方面.
使用牛心膜重建大动脉环 (AAR) 是一种新兴的技术来应对这些挑战.

研究的目的:

评估在SAVR期间在严重性AS患者中使用牛心周的AAR的应用和有效性.
评估这种重建方法的安全性,血液动力学性能和临床结果.

主要方法:

在2021年1月至2023年12月期间,对12名患有严重性AS的患者进行了SAVR和牛心膜AAR的回顾性审查.
通过CT和TTE进行手术前诊断;手术内切除环状切除,牛心周贴片修复和可选的Y切口大动脉环状扩大 (AAE).
随访时间为0.5至2年,评估门功能,血液动力学和并发症.

主要成果:

所有12名患者都接受了牛心周贴片以修复环状缺陷; 5人接受了AAE.
在术后大动脉梯度和速度显著减少 (P < 0.001).
在随访期间没有观察到手术内或手术后的死亡,血液溶解,周泄漏,血栓形成或内心炎.

结论:

在SAVR期间用牛心膜重建大动脉环节,是一种安全有效的方法来管理严重的性AS.

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...
