BACKGROUND: Prolonged fluoroscopy time during coronary angiography is a major concern for interventional cardiologists as well as for patients. It is unknown which factors affect the prolonged fluoroscopy time.
METHODS: A total of 458 patients who underwent diagnostic coronary angiography were included. The patients who had the highest decile of fluoroscopy time were assigned to the prolonged fluoroscopy group (fluoroscopy time ≥15.7min), while the other patients were assigned to the non-prolonged fluoroscopy group (fluoroscopy time <15.7min). We performed univariate and multivariate logistic regression analysis to identify the predictors of prolonged fluoroscopy time.
RESULTS: Mean fluoroscopy time in 458 patients was 8.5±5.8min. Median and ranges of fluoroscopy time were 19.0 [15.7-47.0]min in the prolonged fluoroscopy group and 6.0 [2.0-15.3]min in the non-prolonged fluoroscopy group, respectively. The multivariate logistic regression analysis showed that significant predictors of prolonged fluoroscopy time were prior surgery of ascending aorta replacement [odds ratios (OR) 11.46, 95% confidence intervals (CI) 1.53-85.74, p=0.02] and the prevalence of moderate to severe aortic regurgitation (OR 2.83, 95% CI 1.20-6.66, p=0.02).
CONCLUSIONS: The prior surgery of ascending aorta replacement and moderate to severe aortic regurgitation were significant predictors of the prolonged fluoroscopy time.
