使用Venus-P门进行透气管肺置换 (PVR) 是安全有效的,在中期随访时显示出临床益处和良好的门性能. 最佳的门尺寸和超环形位置可增强门的膨胀和圆形性.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 医疗器械 医疗器械
背景情况:
- 肺膜疾病往往需要干预.
- 透气管肺置换 (PVR) 为手术修复提供了一个不那么侵入性的替代方案.
- 维纳斯-P门是PVR的一个新的选择.
研究的目的:
- 评估过程洞察力,门大小考虑,以及使用Venus-P门进行透导管PVR的结果.
- 在多样化的患者队列中评估Venus-P门植入的安全性和有效性.
- 分析植入物位置 (超环形与跨环形) 对门性能的影响.
主要方法:
- 以后回顾42个连续使用维纳斯-P门的跨导管PVR病例.
- 分析中期随访过程中的手术成功率,不良事件和临床结果.
- 电影光镜测量以评估部署的门几何,扩张和变形.
主要成果:
- 在98%的病例中成功植入Venus-P门.
- 严重不良事件的发生率较低 (膜迁移,心室心律不整,内心炎).
- 在平均20.3个月的随访期内,NYHA类,右心室体积,双心室中风体积和LV喷射率的显著改善.
- 观察到的最高门膨胀和最低离心率在合适度水平.
- 超状植入物与跨状植入物相比,显示出更好的扩张.
结论:
- 使用Venus-P门进行过导管PVR是一种安全有效的程序,具有中期临床益处.
- 仔细的门尺寸,专注于火焰变形和超环状定位,优化门扩张和圆形.
- 需要进一步的后续检查,以确定Venus-P门的长期耐用性和结果.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
