Five patients with abnormalities of the chordae tendineae of the posterior (mural) cusp of the mitral valve have been treated by plication of the cusp, annulus, and atrium in continuity (modified McGoon valvoplasty). They had acute symptoms with physical signs characterized by sinus rhythm and an apical pansystolic murmur radiating to the base of the heart. Investigation showed high left atrial systolic pressures in small atria. Apart from one patient who died of cerebral air embolism with a good haemodynamic result, all were immediately improved and had smooth post-operative courses. Improvement was maintained at follow-up without embolic complications despite stopping anticoagulants.
5例二尖瓣后（壁）瓣叶腱索异常患者接受了瓣叶、瓣环和心房连续折叠术（改良麦古恩瓣膜成形术）治疗。他们有急性症状，体征表现为窦性心律和心尖全收缩期杂音并向心底传导。检查显示小心房的左心房收缩压升高。除1例死于脑空气栓塞但血流动力学结果良好的患者外，所有患者术后立即好转且病程顺利。随访时，尽管停用了抗凝剂，但仍保持改善且无栓塞并发症。
