Origin of both coronary arteries from the same sinus of Valsalva was found in two patients. In one patient the right coronary artery opened from the left sinus of Valsalva, coursed between the pulmonary artery and aorta, disclosed a 95% obstruction in its proximal third with good runoff. The portion of the artery between the aorta and pulmonary artery showed cyclic narrowing during systole. In the second patient the left coronary opened from the right sinus of Valsalva, the left main trunk crossed anteriorily the pulmonary artery conus, and both the circumflex and the left anterior descending branches showed significant narrowing. In both patients the arteries shared a common sinus with two separate orifices, both had bicuspid aortic valve, and in both, nonaberrant coronary vessels also had stigmata of atherosclerosis.
在两名患者中发现冠状动脉均起源于同一个主动脉窦。其中一名患者的右冠状动脉发自左主动脉窦，走行于肺动脉和主动脉之间，在其近端三分之一处有95%的阻塞，但远端血流良好。主动脉和肺动脉之间的动脉段在收缩期出现周期性狭窄。第二名患者的左冠状动脉发自右主动脉窦，左主干向前穿过肺动脉圆锥，回旋支和左前降支均有明显狭窄。两名患者的动脉均共用一个有两个独立开口的主动脉窦，均有二叶式主动脉瓣，且两名患者的非异常冠状动脉血管也都有动脉粥样硬化的特征。
