Abstract:
Objective To explore the X-ray radiation dose to patients from different cardiovascular interventional procedures and analyze the dose-affecting factors.Methods In accordance with the A,B,C operators,442 patients undergoing cardiovascular interventional procedures were collected,including single coronary angiography (CAG),percutaneous coronary intervention ( PCI ),radiofrequency catheter ablation (RFCA),congenital heart disease intervention (CHD) and permanent cardiac pacemaker implantation (PCPI),to observe dose area product (DAP),cumulative radiation dose (CD),fluoroscopy time.Results CD values of patients in groups of CAG,PCI,RFCA,CHD,PCPI were (0.34 ±0.23),(1.33 ±0.76),(0.71 ±0.43),(0.27 ±0.22) and (0.92±0.42) Gy and DAP values were (34.18 ±23.33),(135.92 ±81.14),(79.79 ±50.66),(27.93 ±23.66),and (94.60 ±48.11 ) Gy·cm2,respectively.Fluoroscopy time were (4.82 ±3.73),( 16.64 ±9.01 ),( 17.04 ± 15.29),(9.60 ±5.97)and (7.31 ±6.45) min.DAP values and fluoroscopy time were highly correlated (r =0.84,P < 0.05 ).Conclusions There is significant difference in radiation dose for cardiovascular interventional procedures.Radiation dose and fluoroscopy time are directly related to surgeons' proficiency in operations.Improvement of operation proficiency should be carried out to reduce the patients' radiation dose.
