Abstract

Artificial chordae are increasingly used to repair mitral prolapse. The application of premeasured artificial chordae facilitates the creation of chordae with an appropriate length. Herein, we describe our experience of applying premeasured artificial chordae in 14 cases of mitral prolapse caused by elongated papillary muscles, with an emphasis on the importance of restoring the physiological features of sub-valvular structures during mitral valve repair.

摘要

人工腱索越来越多地用于修复二尖瓣脱垂。预测量的人工腱索的应用有助于创建长度合适的腱索。在此，我们描述了我们在14例由乳头肌延长引起的二尖瓣脱垂病例中应用预测量人工腱索的经验，重点强调了在二尖瓣修复过程中恢复瓣下结构生理特征的重要性。
