We report the case of a 40 yr old previously healthy woman who died suddenly during her second pregnancy from unusual coronary artery anomalies. The left anterior descending coronary artery arose from the above of the right sinus of Valsalva 1.1 cm above the ridge in the aorta and coursed behind the pulmonary valve before it dipped deeply into the myocardium of the interventricular septum. The left circumflex coronary artery was hypoplastic. The right coronary artery arose also from above the right sinus of Valsalva 1.1 cm above the ridge in the aorta but was otherwise normal. A fourth small coronary artery arose between the origins of the left anterior descending and right coronary artery and supplied the outflow tract of the right ventricle. Mild fibrosis was present in the interventricular septum. The rest of the autopsy examination was unremarkable. Such combination of coronary artery anomalies causing sudden unexpected death in a pregnant woman have not previously been reported.
我们报告了一例40岁的既往健康女性病例，她在第二次怀孕期间因不寻常的冠状动脉异常而突然死亡。左前降支冠状动脉起源于主动脉窦右窦上方，距主动脉嵴1.1厘米，在肺动脉瓣后方走行，然后深深潜入室间隔心肌。左旋支冠状动脉发育不良。右冠状动脉也起源于主动脉窦右窦上方，距主动脉嵴1.1厘米，但其他方面正常。第四条小冠状动脉起源于左前降支和右冠状动脉起源之间，供应右心室流出道。室间隔存在轻度纤维化。尸检的其他检查无异常。此前尚未报道过这种导致孕妇突然意外死亡的冠状动脉异常组合。
