概括
假肢-患者不匹配 (PPM) 在快速部署主动脉置换 (RDAVR) 后,女性比男性更常发生. 然而,这并没有影响早期临床结果. 需要进一步的研究来探索特定于性别的PPM定义.
科学领域:
- 心血管外科心血管外科
- 人造心脏门是一种假心脏门.
- 医疗器械 医疗器械
背景情况:
- 假肢-患者不匹配 (PPM) 与手术大动脉置换 (SAVR) 后的不良结果有关.
- 关于PPM结果的性别差异的数据有限.
- 这项研究调查了快速部署主动脉置换 (RDAVR) 后PPM的性别差异.
研究的目的:
- 在接受RDAVR的患者中评估PPM的性别特异性影响.
- 为了确定PPM发生率和结果是否在接受RDAVR的男性和女性之间有所不同.
- 探索假肢选择或尺寸标准中的潜在基于性别的差异.
主要方法:
- 分析了在2018-2023年期间接受RDAVR的256名患者 (60名女性,196名男性) 的队列.
- 根据门学术研究联盟-3 (VARC-3) 标准,使用索引有效孔面积 (EOAi) 定义了PPM.
- 用多变量逻辑回归来确定PPM预测因子.
主要成果:
- 女性在手术前表现出较高的左心室喷射率 (p=0.018).

- 严重的PPM发病率在两性中都很低;在住院死亡率上没有观察到差异.
结论:
- 与男性相比,女性在RDAVR后的PPM发病率较高.
- 在这个队列中,没有发现PPM和早期临床结果之间的相关性.

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...
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 tachycardia.
