Bicuspid aortic valve disease and competitive sports: key considerations and challenges

Abstract

Bicuspid aortic valve (BAV) is a common congenital disorder. It could simply be a minor anatomic abnormality or be associated with progressive aortic stenosis, aortic regurgitation, and aortic dilation. If an athlete is recognized to have a BAV, questions arise with regard to whether they can pursue their selected sports, particularly elite athletic activity, and what type of follow-up examinations are necessary and how often should be done. Valvular disorders such as the degree of aortic stenosis and aortic regurgitation, aortic size, and coexisting disorders are also influencing factors. The absence of robust controlled studies, which are difficult to perform, make decision-making difficult, although recommendations by expert panels provide some guidance. The general consensus is that athletes with BAV with normal valvular function and no aortic dilation can participate in all athletic activities. Those with mild aortic dilation should undergo annual screening, some more frequently than others. Those with moderate or severe valvular stenosis or regurgitation should be managed based on the haemodynamic impact of the valve lesion. Athletes with coexisting lesions or syndromes should be evaluated comprehensively. The overall recommendation to an individual athlete should incorporate many factors and employ a multidisciplinary approach.
