概括

晚期跨导管大动脉置换 (TAVR) 失败可能是由于膜失踪而发生的. 这一案例系列强调了在长期TAVR安全性和耐用性方面需要谨慎.

科学领域:

心血管医学心血管医学
干预心脏病学干预心脏病学
心脏外科手术心脏外科手术

背景情况:

过导管大动脉置换 (TAVR) 是对严重的大动脉狭窄的转变性治疗方法.
虽然TAVR提供了更少的侵入性手术和积极的早期结果,但其长期耐用性仍然不确定.

研究的目的:

报告两例过导管大动脉晚期失效的病例.
提高人们对TAVR潜在的长期并发症的认识.

主要方法:

动脉置换手术 (SAVR) 在患有急性心力衰竭的两名患者中紧急进行.
这种失败归因于TAVR后6-7年发生的突发跨导管大动脉脱离.
胸外心声检查发现了严重的反,手术内发现证实了无退行症的消亡.

主要成果:

两名患者接受了急性心力衰竭的SAVR治疗,原因是TAVR膜衰变.
脱发生在非冠状动脉尖端,没有膜退化的迹象.
术后恢复没有任何事件,在20日和48日出院.

结论:

膜疾病的根本原因尚不清楚.
人们担心类似的TAVR晚期故障的发生率越来越高.
在没有可靠的长期安全数据的情况下,建议在广泛采用TAVR时谨慎.

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 I: Introduction

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
