A rare case of left atrial myxoma associated with ruptured chordae tendineae is presented. The patient was 70-year-old woman, and was diagnosed to have a left atrial myxoma. The myxoma was extirpated together with the atrial septum from which tumor developed. After removal of the myxoma, a ruptured strut chordae tendineae of anterior leaflet was also detected and resutured to the original papillary muscle. The cause of the torn chordae is presumed to be so-called "wrecking ball effect", and to be myxomatous degeneration of the valve.
本文报告一例罕见的左心房黏液瘤合并腱索断裂病例。患者为一名70岁女性,被诊断为左心房黏液瘤。该黏液瘤连同肿瘤起源的房间隔一并切除。切除黏液瘤后,还发现前叶腱索的支柱腱索断裂,并将其重新缝合至原来的乳头肌。腱索撕裂的原因推测为所谓的“破坏球效应”,以及瓣膜的黏液瘤样变性。
