Abstract

Congenital heart defects (CHDs) have been estimated to occur in ∼20% of patients with Brachmann-de Lange syndrome (BDLS, also known as Cornelia de Lange syndrome, OMIM122470). We report on the results of a prospective echocardiographic evaluation of a cohort of 87 Italian BDLS patients with longitudinal follow-up from 5 to 12 years. A cardiac anomaly was identified in 29/87 (33.3%) including 28 (32.2%) patients with a structural CHD, and an additional patient (1.2%) with isolated non-obstructive hypertrophic cardiomyopathy (HCM). Of the 28 patients with a CHD, 12 (42.9%) had an isolated obstructive CHD, 10 of which were pulmonary stenosis (36%), 8 (28.6%) had an isolated left to right shunt, and the remainder showed a combination of structural anomalies. Overall incidence of pulmonary stenosis was 39% (11/28). Isolated late-onset mitral or tricuspid valve dysplasia, albeit hemodynamically insignificant, was detected at follow-up examination in 4 (14.3%) patients older than 10 years, previously known to be normal. In contrast to previous studies, only two patients required surgery, one for closure of a large perimembranous ventricular septal defect (VSD) and associated ASD closure (1), and another for VSD closure and relief of pulmonary valve stenosis (1). The remainder are receiving medical follow-up.Webelieve that the overall frequency (33.3%) and evidence of 4 late onset dysplastic valves anomalies justifies both echocardiographic assessment in all BDLS patients at the first diagnostic assessment, and later on during medical follow-up.
