| Abstract:: |
| Objective To compare the X-ray radiation dose from atrial fibrillation (AF) ablation guided by magnetic navigation system (MNS) and manual procedure (CON). Methods 94 AF patients were randomly divided into MNS group (34 cases) and CON group(60 cases). The dose area product (DAP), cumulative radiation dose (CD), fluoroscopy time of patients, the X-ray exposure time and dose of operators were recorded and analyzed. Results The results from the patients in MNS group and CON group were CD values (0.54±0.45) and (1.61±0.89) Gy (t=2.44,P<0.05), DAP values (46.86±27.09) and (139.71±76.69) Gy·cm2(t=3.89,P<0.05) and fluoroscopy time (15.60±7.52) and (39.50±8.82) min (t=1.96,P<0.05), respectively. The X-ray exposure dose in both groups were (22.68±6.87) and (62.74±20.92) μSv (t=2.02,P<0.05) for operation doctor (19.38±5.64) and (49.42±10.67) μSv (t=3.58, P<0.05) for operation assistant and (18.98±4.99) and (47.77±13.65) μSv (t=3.17,P<0.05) for nurse, respectively. The X-ray exposure time experienced in both groups were (11.48±7.59) and (30.50±14.82) min (t=2.75,P<0.05) for operation doctor, (8.96±5.88) and (24.49±9.09) min (t=4.20,P<0.05) for operation assistant and (8.33±6.35) and (22.99±13.36) min(t=2.76,P<0.05) for nurse, respectively. Conclusions Compared with manual procedure, the MNS applied in AF ablation has the potential to decrease X-ray exposure dose. |
