Although bicuspid aortic valve (BAV) disease is relatively rare in the general population, the frequency is high in patients requiring valve surgery. The aim of the current study was to characterise the different phenotypes of BAV disease by CMR.Methods CMR studies were performed on a 1.5 T scanner in 105 patients with BAV.Results The pattern of BAV phenotypes was as follows: a raphe was identified in 90 patients (86%). Among patients with raphe, 76 patients had fusion between the right and left cusps (RL) and 14 patients had fusion between the right and the non-coronary cusps (RN). There were no significant differences in the aortic dimensions in the different BAV phenotypes.Conclusion CMR allows excellent characterisation of valve phenotype in patients with BAV. The present data demonstrate that a raphe is present in the vast majority of cases and RL fusion is the predominant phenotype of BAV. No significant differences in the aortic dimensions were observed. ER -
