Impact of single‐plane versus Bi‐plane imaging on procedural time, fluorescence time, and contrast medium volume in retrograde chronic total occlusion percutaneous coronary intervention

Objective The aim of the study is to evaluate the impact of single‐plane and bi‐plane imaging on procedural time, fluorescence time, and contrast medium volume in retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Methods Between January 2008 and December 2015, a total of 359 patients received scheduled retrograde CTO PCI and were enrolled in the study; 119 patients underwent PCI by single‐plane imaging, and another 240 patients underwent PCI by bi‐plane imaging. Results A 95.0% rate of technical success was noted in the single‐plane imaging group, and a 95.8% rate of technical success was noted in the bi‐plane imaging group. All patients received the CTO approach via the retrograde method, and the retrograde method success rate was 88.2% in single‐plane imaging group, and 81.7% in the bi‐plane imaging group. A longer procedural time (153.73 ± 53.15 vs 172.88 ± 61.30 min; P = 0.004), longer fluorescence time (71.40 ± 25.96 vs 80.95 ± 34.70 min; P = 0.008), and more contrast medium volume (342.77 ± 102.25 vs 394.58 ± 156.41 mL; P = 0.001) were noted in the bi‐plane imaging group. After propensity score match, a longer procedural time, longer fluorescence time, and more contrast volume was noted in bi‐plane group. Conclusion Bi‐plane imaging could not decrease procedural time, fluorescence time, and contrast medium volume in retrograde CTO PCI.
