概括
大动脉置换后患者与假肢不匹配 (PPM) 可能会轻微影响存活率,特别是严重的PPM. 然而,在这项为期15年的研究中,PPM与重新操作风险没有显著联系.
科学领域:
- 心脏病学 心脏病学
- 心脏外科手术 心脏外科手术
- 生物材料科学 生物材料科学
背景情况:
- 患者与假肢不匹配 (PPM) 是大动脉置换 (AVR) 后的一个潜在问题.
- PPM对长期结果的影响,包括死亡率和重新手术,需要进一步调查.
研究的目的:
- 评估PPM与生物AVR后的长期死亡率之间的关联.
- 在15年的随访期间评估PPM和重新运行率之间的关系.
主要方法:
- 分析了2000-2007年间接受生物AVR的645名患者队列.
- 在手术后6个月,PPM被指数化有效孔径面积 (<0.85厘米2/m2) 定义.
- 长期存活和重新操作的数据收集了超过15年的时间.
主要成果:
- 在40%的患者中发现了PPM (175例中度,81例重度).
- 严重的PPM显示出与生存能力受损的边际显著关联 (HR1.40,P=.054),而中度的PPM则没有.
- 没有发现PPM与重新操作风险 (P > .2) 之间有显著的关联.
结论:
- 通过直接测量有效孔面积来评估的PPM,表明与长期存活的边际关系.
- 在这个队列中,没有发现PPM是重新干预风险的统计学上显著的预测因素.

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.
