Abstract:
Objective To clarify whether the use of dynamic coronary artery roadmap(DCR)technology in a low-dose mode with 7.5 frames per second during coronary intervention can further reduce the total radiation dose,fluoroscopy time,and contrast agent usage.Methods A total of 94 patients,who received coronary angiography at the Shanghai Tongji Hospital of China between July 2022 and December 2022,were enrolled in this study.The patients were randomly divided into DCR group(n=53)and control group(n=41).DCR technology was used in the DCR group to guide the performance of percutaneous coronary intervention(PCI),while low-dose mode coronary angiography was adopted in the control group.The total air kerma(AK),dose-area product(DAP),intraoperative fluoroscopy time,and contrast agent usage were compared between the two groups.Results In the DCR group AK was(597.9±222.8)mGy,which was significantly lower than(717.0±326.8)mGy in the control group(P=0.039);DAP was(33.2±13.3)Gycm2/s,which was also remarkably lower than(41.3±21.5)Gycm2/s in the control group(P=0.027).In the DCR group and the control group,the intraoperative fluoroscopy time was(9.8± 3.3)min and(12.1±4.3)min respectively(P＜0.01),and the contrast agent usage was(122.3±19.0)mL and(130.5± 28.5)mL respectively(P=0.116).Conclusion In a low-dose mode during coronary intervention,the use of DCR technology can further reduce radiation dose,fluoroscopy time,and contrast agent usage.(J Intervent Radiol,2024,33:236-239)
