BACKGROUND: Valvar abnormalities in children and adults with autosomal dominant polycystic kidney disease (ADPKD) have previously been reported as a frequent occurrence. Mitral valve prolapse (MVP), in particular, has been reported in almost one-third of adult patients and nearly 12% of children with ADPKD. Our objective in this study was to establish the prevalence of valvar abnormalities in a large, contemporary series of children and young people (CYP) with ADPKD.
METHODS: A retrospective, single centre, cross-sectional analysis of the echocardiograms performed on all consecutive children seen in a dedicated paediatric ADPKD clinic. Full anatomical and functional echocardiograms were performed and analysed for valvar abnormalities.
RESULTS: The echocardiograms of 102 CYP with ADPKD (range 0.25-18 years, mean age 10.3 years, SD ± 5.3 years) were analysed. One (0.98%), 3-year-old boy, had MVP. There was no associated mitral regurgitation. Evaluating variations in normal valvar anatomy, 9 (8.8%) patients, aged 7.1 to 18 years, had minor bowing ± visual elongation of either the anterior or posterior leaflet of the mitral valve, none of which fell within the criteria of true MVP. Three (1.9%) patients, 2 boys and 1 girl aged between 7 and 14 years, had trivial or mild aortic regurgitation. No patients had echocardiographic evidence of tricuspid valve prolapse (TVP).
CONCLUSION: In this contemporary cohort of CYP with ADPKD, the incidence of MVP and other valvar lesions is significantly lower than previously reported. A higher resolution version of the Graphical abstract is available as Supplementary information.
