目的：报道３例主动脉－左室隧道并讨论其最佳心血管造影投照角度。材料与方法：３例主动脉－左室隧道均由心血管造影作出诊断。３例都为男性，年龄从２岁至１１岁。诊断时采用不同角度的升主动脉及左心室造影。结果：所有３例均经手术证实。右前斜位升主动脉造影对隧道直接征象显示最好。结论：右前斜位升主动脉造影是诊断这一罕见先天性心脏病的最佳心血管造影体位。
OBJECTIVE: To report three cases of aorta-left ventricular tunnel and discuss the optimal angiographic projection angle. Materials and Methods: Three cases of aorta-left ventricular tunnel were diagnosed by angiography. All three cases were male, ranging in age from 2 to 11 years. Diagnostic use of different perspectives of the ascending aorta and left ventricular angiography. Results: All three cases were confirmed by surgery. Right anterior oblique ascending aortography showed direct tunnel signs the best. Conclusion: Right anterior oblique ascending aortography is the best place to diagnose this rare congenital heart disease.
