The authors report their experience of 21 revision operations for malfunction of the Beall Surgitool 104 prosthesis used in the mitral position. The incidence and uniformity of the disorders found in the prostheses suggest that these changes are produced inevitably usually during the fourth year. The disc becomes kinked, the mountings eroded, and the teflon ring torn. The clinical features are the onset of heart failure, anaemia, or a thrombo-embolic episode. These three findings may occur individually or in association. The authors do not advise systematic revision surgery, but conclude that close follow-up is essential in the case of all patients who have had a Beall prosthesis. Early signs of failure should be revealed by clinical examination, the level of LDH, and by phonocardiogram and echocardiogram studies. Leaving aside thrombo-embolic episodes and severe anaemia which themselves constitute indications for revision surgery, the decision to replace the damaged prosthesis should be taken as soon as the first signs of cardiac failure are detected.
作者报告了他们对21例二尖瓣位使用的Beall Surgitool 104人工瓣膜功能障碍进行翻修手术的经验。在人工瓣膜中发现的病变发生率和一致性表明，这些改变通常在第四年不可避免地出现。瓣膜盘扭结、固定装置侵蚀、聚四氟乙烯环撕裂。临床特征为心力衰竭、贫血或血栓栓塞事件的发作。这三种表现可能单独出现或同时出现。作者不建议进行系统性翻修手术，但得出结论，对于所有接受过Beall人工瓣膜置换的患者，密切随访至关重要。临床检查、乳酸脱氢酶水平、心音图和超声心动图研究应能揭示早期失败迹象。除了血栓栓塞事件和严重贫血本身构成翻修手术的指征外，一旦检测到心力衰竭的最初迹象，就应决定更换受损的人工瓣膜。
