Abstract

Background: The aim of this study was to identify a possible link between bicuspid aortic valve (BAV) and premature ventricular beats (PVBs), particularly from left and right ventricular outflow tracts, and to investigate possible associations between these arrhythmias and echocardiographic abnormalities.

Methods: A comparison of sportspeople with and without BAV was performed to identify PVBs' occurrence in these two series. Then, subdividing the BAV group on the presence of cardiovascular complications due to BAV, we compared arrhythmic features between these two subgroups and echocardiographic findings between athletes with and without left and right outflow tract PVBs.

Results: PVBs in 343 athletes with BAV were compared with 309 athletes without BAV, showing an increased frequency (29% vs. 11.8%, p < 0.001; OR 3.1; CI 2.1-4.7) and origin from the left (18.4% vs. 3.2%, p < 0.001, OR 6.7; CI 3.4-13.4) and right (15.2% vs. 3.6%, p < 0.001, OR 4.8; CI 2.5-9.5) outflow tracts compared to other ventricular areas (fascicular PVBs p = 0.81, other morphologies p = 0.58). No difference in PVBs' occurrence was found between near normal valve BAV and pathological BAV, nor was a difference in echocardiographic characteristics found between patients with and without outflow tract arrhythmias.

Conclusions: A possible causal link between BAV and PVBs was highlighted, but no association between PVBs and complicated BAV was emphasized.
