概括
在具有具有挑战性解剖的患者中,通过透气管的大动脉植入 (TAVR) 的交叉式 (TAx) 接入是可行的,其早期临床结果与输血管 (TF) 接入相似. 需要进一步的随机研究来证实这些有希望的发现.
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
- 手术创新 在外科创新.
背景情况:
- 交叉门 (TAx) 接入是跨导管大动脉植入 (TAVR) 的新兴替代方案,特别是在患有困难的 iliofemoral 解剖学的患者中.
- 这项研究评估了TAx接入的早期临床结果,与TAVR.TAVR的传统输接入 (TF) 相比.
研究的目的:
- 在接受过导管大动脉植入 (TAVR) 的患者中,比较交叉 (TAx) 与输血 (TF) 接入的早期临床结果.
- 评估TAx TAVR的可行性和安全性,作为TF访问禁用时的替代接入路线.
主要方法:
- 一个回顾性观察性研究,利用来自未来RISPEVA注册表的数据.
- 从2013年起,包括2164名连续TAVR患者,TAx是TF访问的唯一替代方案.
- 在TAx (n=60) 和TF (n=2104) 组之间的基线特征,程序数据和1个月临床结果的比较.
主要成果:
- 尽管TAx组的外科风险得分和并发病率较高,但手术成功率相似 (TAx: 96.7%,TF: 98.7%).
- 在1个月的随访中,在所有原因的死亡率,中风,心肌梗塞,主要血管并发症或主要出血方面没有观察到任何显著差异.
- 综合终点也显示没有显著差异 (TAx: 11.7%,TF: 7.4%).
结论:
- 交叉式TAVR是一种可行的替代性接入途径,产生有利的短期临床结果,与输血门接入相美.
- 这些发现虽然有希望,但来自单一中心的回顾性研究,需要通过前性随机试验进行验证.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
