Percutaneous closure of perivalvular regurgitation may be complicated by prosthetic valve impingement and dysfunction. We describe a patient with two perimitral defects who developed severe mitral stenosis due to mitral leaflet impingement after percutaneous implantation of three amplatzer muscular ventricular septal defect occluder devices. The largest amplatzer occluder device was successfully snared with restoration of normal prosthetic valve motion.
经皮瓣周反流封堵术可能因人工瓣膜撞击和功能障碍而变得复杂。我们描述了一名患者，他在经皮植入三个 Amplatzer 肌部室间隔缺损封堵器后，由于二尖瓣瓣叶撞击而导致二尖瓣瓣周两个缺损，出现严重的二尖瓣狭窄。最大的 Amplatzer 封堵器成功地被圈套捕获，恢复了正常的人工瓣膜运动。
