A 1.5-year-old boy with refractory heart failure due to congenital mitral stenosis exhibited fusion of the anterolateral leaflets associated with moderate mitral regurgitation due to absent anterolateral chordae. Fused leaflets were incised and the mitral valve opening improved. Mitral regurgitation increased due to the absence of chordae, so 2 pairs of artificial chordae of 5-0 expanded polytetrafluoroethylene suture were anchored to the hypoplastic anterolateral papillary muscle, then attached to the free margin of incised leaflets. Postoperative examination showed improved mitral opening without exacerbated mitral regurgitation.
一名1.5岁因先天性二尖瓣狭窄导致难治性心力衰竭的男孩，表现为前外侧瓣叶融合，并因前外侧腱索缺如伴有中度二尖瓣反流。切开融合的瓣叶后二尖瓣开口改善。由于腱索缺如，二尖瓣反流增加，因此将2对5-0膨体聚四氟乙烯缝线制成的人工腱索固定于发育不良的前外侧乳头肌，然后连接至切开瓣叶的游离缘。术后检查显示二尖瓣开口改善且二尖瓣反流未加重。
