Abstract:
Objective To evaluate the application of multi-slice computed tomographic coronary angiography in diagnosis of chronic total occlusion (CTO) of coronary artery.Methods Six hundred and thirty eight patients were diagnosed as CTO disease with coronary angiography (CAG) from June 2011 to December 2012 in Zhongshan Hospital;236 of them received multi-slice computed tomographic coronary angiography in 60 days before.Results In total 708 vessels of the 236 patients,244 vessels were proved totally occluded,128 (52.5％) of which were located in left anterior descending artery,31 (12.7％) were located in left circumflex coronary artery and 85 (34.8％) located in right coronary artery.Multi-slice computed tomographic coronary angiography was superior to CAG in judgment of stump anatomy (64.3％ vs.52.5％,F =7.09,P =0.010),plaque calcification (40.2％ vs.26.2％,F =10.68,P =0.001) and distal vessel interpretability (93.9％ vs.74.6％,F =34.06,P ＜ 0.001).There was no significant difference in judging side branch,tortuosity and lesion length between multi-slice computed tomographic coronary angiography and CAG (all P ＞ 0.05).Conclusion Multi-slice computed tomographic coronary angiography provides more detailed anatomy information of CTO lesions and is of value in diagnosis and treatment of CTO lesions.
