概括

对于50-70岁的接受主动脉置换 (AVR) 的患者,生物假体和机械的长期存活率相似. 生物假体是一个合理的选择,尽管机械提供更长的耐用性.

科学领域:

心脏病学心脏病学
心脏外科手术心脏外科手术
生物医学工程生物医学工程

背景情况:

大动脉膜疾病 (AVD) 是导致心脏膜疾病 (VHD) 死亡的一个重要原因.
目前的指导方针建议50岁以下的患者使用机械门,70岁以上的患者使用生物假体门进行主动脉置换 (AVR).

研究的目的:

在接受AVR的50-70岁患者中,比较生物假体与机械门的长期结果.
为了评估这个特定年龄组的门类型之间的死亡率,发病率和重新操作率的差异.

主要方法:

对接受AVR的744名患者 (2:1比) 的倾向匹配分析.
结果的比较,包括生物假体和机械接收者之间的死亡率,发病率和重新操作率.

主要成果:

两组之间没有观察到30天死亡率或并发症率的显著差异.
在1,5年和15年的长期死亡率对于生物假体和机械门都是相似的.
虽然5年和10年后的重复手术率相似,但生物假体门在15年后的重复手术可能性更高 (21.2%对比9.7%).

结论:

在50-70岁的患者中,大动脉置换产生了类似的长期结果,无论门类型如何.
生物假体门是一个可行的选择,因为其低的重新操作率,死亡率和避免抗凝血.
机械门对年轻患者保持了耐用性的优势,而生物假体门适合50-70岁的年龄组.

关键词:

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...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
