图1 经胸超声心动图胸骨旁长轴切面可见主动脉根部一强回声占位（箭头所示）图2 经胸超声心动图胸骨旁短轴切面显示左冠状动脉内支架突入主动脉根部管腔内（箭头所示）注：LCA为左冠状动脉

图3 经食管超声心动图短轴切面显示左冠状动脉内支架突入主动脉根部管腔内（箭头所示）图4 三维经食管超声心动图显示左冠状动脉内支架突入主动脉根部管腔内注：AO为主动脉

图5 二维斑点追踪超声心动图左心室整体纵向应变牛眼图示左心室收缩功能正常，无节段性室壁运动异常

图6 冠状动脉CT血管造影检查示左冠状动脉内支架部分突入主动脉根部管腔内，前降支各段管腔偏细（图a为左冠状动脉主干层面成像；图b为冠状动脉CT三维重建图像）
