Figure 2

Schematic representation of A) a normal — tricuspid — aortic valve with the 3 cusps, B) a bicuspid valve with right-left coronary cusp fusion and one raphe (the line of union between the fused cups), C) a bicuspid valve with fusion of the right-left coronary cusps and no raphe, D) a bicuspid valve with right-non coronary cusp fusion and one raphe and E) a bicuspid valve with fusion of the left-non coronary cups and one raphe. LC, left coronary; LCA, left coronary artery; NC, non-coronary; RC, right coronary; RCA, right coronary artery.
