摘　　要：目的探讨先天性左心耳缺如的临床及CT影像表现,以提高对先天性左心耳缺如的诊断认识水平。方法回顾性分析43405例心脏冠状动脉检查患者原始影像资料,通过横断面(CS)、多平面重建(MPR)、曲面重建(CPR)、最大密度投影(MIP)及容积再现(VR)图像等后处理,最终发现11例先天性左心耳缺如患者。结果11例患者先天性左心耳缺如中男8例,女3例,其中7例近期内行心脏彩超检查,5例患者心脏射频消融术中造影。结论先天性左心耳缺如CT影像表现具有一定特征性。Objective To investigate the CT features of congenital left atrial appendage and to improve the diagnostic level of congenital left atrial appendage.Methods The original imaging data of 43405 patients with coronary artery examination were analyzed retrospectively.11 patients with congenital left atrial appendage were found by cross section(CS),multiplane reconstruction(MPR),curved reconstruction(CPR),maximum density projection(MIP)and volume reconstruction(VR)images.Results There were 8 males and 3 females in the 11 patients with congenital absence of left atrial appendage.Among them,7 patients underwent color doppler echocardiography and 5 patients underwent radiofrequency ablation.Conclusion The CT findings of congenital absence of left atrial appendage have certain characteristics.
