Congenital mitral regurgitation continues to present a challenge for cardiac surgeons because of the diversity of the anatomy of the congenitally malformed mitral valve. We undertook aggressive repair of the mitral valve with artificial chordae for reconstruction of the prolapsed anterior leaflet in some children. The short-term results are reported herein.
Three patients with isolated congenital mitral regurgitation underwent mitral valve repair with use of expanded polytetrafluoroethylene sutures as artificial chordae.
There have been no late deaths and no valve-related complications. Serial follow-up echocardiographic examinations have not revealed any increase in the severity of mitral regurgitation with continuing patient growth up to 39 months after the operation.
When combined with other conservative methods of mitral valve repair, chordal replacement with expanded polytetrafluoroethylene sutures in children undergoing mitral valve reconstruction produces good short-term results. We believe that it delays and possibly prevents the need for a mechanical prosthesis with its associated complications in this young patient population.
先天性二尖瓣反流由于先天性畸形二尖瓣解剖结构的多样性，持续给心脏外科医生带来挑战。我们对一些儿童采用人工腱索积极修复二尖瓣，以重建脱垂的前叶。本文报告短期结果。
3例孤立性先天性二尖瓣反流患者使用膨体聚四氟乙烯缝线作为人工腱索进行二尖瓣修复。
无晚期死亡病例，也无瓣膜相关并发症。系列随访超声心动图检查未显示二尖瓣反流严重程度随患者术后持续生长至39个月而增加。
在二尖瓣重建的儿童中，膨体聚四氟乙烯缝线替代腱索与其他二尖瓣修复保守方法联合应用可产生良好的短期效果。我们认为，这在该年轻患者群体中可延迟并可能避免使用机械瓣膜及其相关并发症。
