Abstract

Spontaneous closure of an atrial septal defect (ASD) is well described in pediatric cardiology but may be less familiar to adult internists and cardiologists. We report a moderately sized 6-mm ASD that closed spontaneously without intervention. A literature review found that a smaller defect size and an early age of diagnosis are the most important predictors of closure. Possible mechanisms of a spontaneous ASD closure include adaptive endothelial migration, limited myocardial proliferation, and fibroblast migration with extracellular matrix deposition.

摘要

房间隔缺损(ASD)的自然闭合在小儿心脏病学中有详细描述,但成年内科医生和心脏病专家可能对此不太熟悉。我们报告了一例直径6毫米的中等大小ASD,未经干预而自然闭合。文献综述发现,较小的缺损尺寸和较早的诊断年龄是闭合的最重要预测因素。ASD自然闭合的可能机制包括适应性内皮迁移、有限的心肌增殖以及成纤维细胞迁移和细胞外基质沉积。
