Mitral Annulus Disjunction, Annuloaortic Ectasia, and Pseudoaneurysm of Aortomitral Interannular Fibrosa in a 2-Year-Old Child

Abstract

Genetically determined deficiency of connective tissue predisposes to the prolapsed mitral valve and an abnormal fibrous annulus including mitral annulus disjunction and dehiscence of aortomitral annular fibrosa. In a more severe phenotype, there may be abnormal aortic tissue, leading to annuloaortic ectasia. This report describes a 2-year-old male child who presented with failure to thrive and was found to have Barlow's syndrome with bileaflet mitral valve prolapse and mitral annulus disjunction, annuloaortic ectasia, and a pseudoaneurysm of interannular fibrosa. The case is reported for its interesting unifying linkage among various defects.
