In a necropsy study, the conjoined cusps of 50 congenitally and 50 acquired bicuspid aortic valves most commonly involved the right and left aortic cusps. In hearts with congenitally bicuspid aortic valves, the left coronary ostium arose at or above the aortic sinotubular junction in 44 per cent, whereas the incidence for the left coronary ostium in the acquired group was 20 per cent and that for the right coronary ostium in both groups was less than 20 per cent. In hearts with congenitally bicuspid aortic valves, the incidence of left coronary dominance (26%) was higher than in normal hearts. In hearts with apparently acquired bicuspid aortic valves, this incidence was also higher than normal, possibly because of acquired fusion of atypical congenitally bicuspid valves in some cases. In both types of aortic valve disease, the length of the left main coronary artery was similar; this length, however, was significantly shorter in hearts with left coronary dominance than in those with right or shared dominance.
在一项尸检研究中，50个先天性和50个后天性二叶式主动脉瓣的连合瓣叶最常累及右主动脉瓣叶和左主动脉瓣叶。在先天性二叶式主动脉瓣的心脏中，44%的左冠状动脉口位于主动脉窦管交界处或其上方，而后天性组中左冠状动脉口的发生率为20%，两组中右冠状动脉口的发生率均低于20%。在先天性二叶式主动脉瓣的心脏中，左冠状动脉优势型（26%）的发生率高于正常心脏。在明显为后天性二叶式主动脉瓣的心脏中，这一发生率也高于正常，可能是因为在某些情况下非典型先天性二叶式瓣膜发生了后天融合。在两种类型的主动脉瓣疾病中，左冠状动脉主干的长度相似；然而，左冠状动脉优势型的心脏中该长度明显短于右冠状动脉优势型或共优势型的心脏。
