报道68例选择性DSA冠状动脉造影X线表现。其中右冠优势型50例（75．8％），左冠优势型10例（15．2％），均衡型7例（9％）。冠心病36例（53％），共累及61支冠脉分支：单支病变17例（47．3％），双支病变13例（36％），三支病变6例（16．7％）。25例左心室造影：左心室运动功能正常20例，异常者5例，室壁病8例，二尖瓣返流7例。左室射血分数LVEF与冠状动脉狭窄程度和室壁病有明显关系。着重对冠心病冠状动脉造影诊断及其误漏的原因进行分析。
68 cases of selective DSA coronary angiography X-ray findings. There were 50 cases (75.8%) with dominant right coronary artery, 10 cases (15.2%) with dominant left coronary artery and 7 cases (9%) with balanced coronary artery. Thirty-six coronary arteries (53%) were involved in 61 coronary artery branches: 17 (47.3%) with single vessel disease, 13 (36%) with double vessel disease and 6 (16.7%) with three vessel disease . 25 cases of left ventricular angiography: normal left ventricular function in 20 cases, 5 cases of abnormalities, 8 cases of ventricular wall disease, mitral regurgitation in 7 cases. Left ventricular ejection fraction LVEF and coronary artery stenosis and ventricular wall disease have a significant relationship. Focus on Coronary angiography coronary angiography diagnosis and causes of error analysis.
