The successful second-replacement of mitral valve prostheses in two children, age 5 and 9 years, is reported. In one, a parachute mitral valve deformity was first corrected at the age of 10 months by the small-size 00 Starr-Edwards prosthesis. The second child had mitral valve disease caused by Marfan's syndrome 1; the valve was initially replaced at the age of 3 years by a size 0 Starr-Edwards prosthesis. For both patients, in the period between the two interventions, the left ventricle had grown in size and the mitral anulus was not a limiting factor in the insertion of a larger prosthesis of the Björk-Shiley type. Follow-up periods of 1 and 6 years, respectively, confirm excellent clinical results. Problems concerning valve replacements in pediatric patients are discussed.
本文报道了两例儿童二尖瓣人工瓣膜再次置换成功的病例，患儿年龄分别为5岁和9岁。其中一例，患儿10个月大时因降落伞样二尖瓣畸形首次接受了小型00号Starr-Edwards人工瓣膜置换术。另一例患儿患有马凡氏综合征1型所致的二尖瓣疾病，3岁时首次接受了0号Starr-Edwards人工瓣膜置换术。对于这两名患者，在两次手术间隔期间，左心室增大，二尖瓣环并非植入更大型号Björk-Shiley型人工瓣膜的限制因素。分别为1年和6年的随访期证实临床效果极佳。文中还讨论了小儿患者瓣膜置换的相关问题。
