INTRODUCTION: Reduction of radiation exposure during cardiac arrhythmia ablation procedures is desirable. We sought to evaluate the utility of a new image integration module (CARTOUNIVU(TM) ) in reducing fluoroscopy times and dosages during left atrial arrhythmia (LAA) and ventricular tachycardia (VT) ablation procedures. METHODS AND RESULTS: Consecutive patients undergoing LAA (n = 28)/VT (n = 13) ablation using the CARTOUNIVU(TM) module were included. Total fluoroscopy time, radiation dose (total dose area product [tDAP], effective dose [ED]), and procedure duration were evaluated. A retrospective cohort of patients who underwent LAA (n = 16)/VT(n = 8) ablation without the new image integration module served as a control group. The use of the new image integration module significantly reduced mean fluoroscopy time (5.2 minutes [IQR 1.9;6.8] in the LAA ablation UNIVU group vs. 28.2 minutes [IQR 15.3;37.8] in the control group, P<0.001; 9.8 minutes [IQR 4.5;13.1] vs. 25.5 minutes [IQR 14.1;30.9] for VT ablation, P = 0.013), tDAP (2,088 cGy*cm(2) [IQR 664;2911] vs. 5,893 cGy*cm(2) [IQR 3088;8483], P< 0.001 for LAA ablation; 3,917 cGy*cm(2) [IQR 948;4217] vs. 12,377 cGy*cm(2) (IQR 3385;23157) for VT ablation patients, P = 0.025) and ED (4.1 mSv [IQR 1;5.8] vs. 11.8 mSv [IQR 6.2;16.9] for LAA ablation patients, P< 0.001; 7.8 mSv [IQR 1.9;8.4] vs. 24.7 mSv [IQR 6.8;46.3] for VT ablation patients, P = 0.025). Procedure duration did not significantly change (174 ± 45 minutes vs. 197 ± 36 minutes for LAA ablation, P = 0.083; 201 ± 51 minutes vs. 201 ± 63 minutes for VT ablation, P = 0.860). No serious adverse events related to the use of the CARTOUNIVU(TM) module occurred. CONCLUSIONS: The new image integration module significantly reduced total fluoroscopy time and mean radiation dose without influence in procedure duration during ablation of complex atrial and ventricular arrhythmias.
