The results in 22 patients in the Denver area with Wada-Cutter prostheses were reviewed. There were 14 late deaths, with an average follow-up of six years. Four cases of valve malfunction not related to thrombosis were documented. There were three cases of embolization of the occluder. A survivor is reported. Clinical evaluation of the group suggested new mitral regurgitation to be a sensitive indicator of impending embolization of the occluder. Documentation of valve malfunction warrants valvular replacement.
回顾了丹佛地区22例使用瓦达-卡特假体患者的结果。有14例晚期死亡，平均随访6年。记录了4例与血栓形成无关的瓣膜功能障碍病例。有3例封堵器栓塞病例。报告了1例存活者。该组的临床评估表明，新发二尖瓣反流是封堵器即将发生栓塞的敏感指标。瓣膜功能障碍的记录表明需要进行瓣膜置换。
