Research paper thumbnail of Bicuspid aortic valve phenotype relationship with aortic root morphology and elasticity

European Heart Journal, 2013

Results: Of the 401 FDR recruited: 113 (28.1%) refused the study and 288 (71.9%) underwent screening (mean age: 36.1±19 years; 66.7% males). Twentyone aortic valve abnormalities were encountered: 20 BAV and 1 quadricuspid valve, distributed in 17 of the 90 families, yielding a BAV family prevalence of 18.8% (Table). BAV phenotype was not consistent among probands and positive FDR in 6 of the affected families (35.3%). The prevalence of BAV among the FDR screened was 7.3%, higher than that reported in the general population (0.5-1.0%). The number of FDR required to screen for identifying a new BAV case is 14, in contrast to 100 in the general population. Conclusions: The prevalence of BAV is higher in FDR of BAV patients than in the general population. Discordance between BAV phenotypes within the same family is not rare. Echocardiographic screening of FDR is a useful approach for identifying asymptomatic cases, and should therefore be offered to all FDR of BAV individuals.
