Abstract:
Objective To evaluate the clinical safety and feasibility of dual-axis rotational coronary angiography (XperSwing) in diagnosing coronary artery disease in aged Chinese patients through comparing it with standard coronary angiography. Methods During the period from April 2011 to December 2012, a total of consecutive 151 patients with an age ≥ 65 years underwent diagnostic coronary angiography at authors’ hospital. The patients were randomly divided into the standard angiography group (n = 75) and XperSwing group (n = 76). The used dose of contrast, radiation exposure dose and operation time of each patient were recorded. Besides, the occurrence of procedure-related symptoms and arrhythmia during the procedure was recorded, and the blood pressure (BP), heart rate (HR) and creatinine level immediately before-and-after the procedure were estimated. The number of additional acquisition needed to be performed was used to evaluate the efficacy of the two methods. Results Coronary angiography was successfully accomplished in all patients of the two groups, and no significant difference in the number of additional acquisition existed between the two groups (P > 0.05). The used dose of contrast in XperSwing group was reduced by 44% when compared with that in the standard angiography group, i.e. (29.28 ± 5.06) ml vs(22 755.97 ± 11 239.22) mGycm2, (P<0.001). No statistically significant differences in the occurrence of procedure-related symptoms and arrhythmia during the procedure, in the operation time as well as in the postoperative changes of BP and HR existed between the two groups (P > 0.05). No contrast- induced nephropathy occurred in both groups, although the difference in postoperative changes of creatinine level between the two groups was statistically significant (P < 0.05). Conclusion This study indicates that in diagnosing coronary artery disease in aged Chinese patients, dual-axis rotational coronary angiography is more safe and effective than conventional coronary angiography, as XperSwing can significantly reduce the contrast dose and radiation exposure for the patients.
