Aims: Intracardiac echocardiography (ICE) is a relatively young technique used during complex electrophysiology proce-dures, such as atrial fibrillation (AF) ablation. The aim of this study was to assess whether the use of ICE modifies the radia-tion exposure at the beginning of the learning curve in AF ablation. Materials and methods: In this retrospective study, 52 patients, in which catheter ablation for paroxysmal or persistent AF was performed, were included. For 26 patients we used ICE guidance together with fluoroscopy, whereas for the remaining 26 patients we used fluoroscopy alone, all supported by electroanatomical mapping. We compared total procedure time and radiation exposure, including fluoroscopy dose and time between the two groups and along the learning curve. Results: Most of the patients included were suffering from paroxysmal AF (40, 76%), pulmonary vein isolation being performed in all patients, without secondary ablation sites. The use of ICE was associated with a lower fluoroscopy dose (11839.60±6100.6 vs. 16260.43±8264.5 mGy, p=0.041) and time (28.00±12.5 vs. 42.93±12.7 minutes, p=0.001), whereas the mean procedure time was similar between the two groups (181.54±50.3 vs 197.31±49.8 minutes, p=0.348). Radiation exposure was lower in the last 9 months compared to the first 9 months of the study (p<0.01), decreasing gradually along the learning curve. Conclusions: The use of ICE lowers radiation exposure in AF catheter ablation from the beginning of the learning curve, without any difference in terms of acute safety or efficacy. Aware-ness towards closest to zero radiation exposure during electrophysiology procedures should increase in order to achieve better protection for both patient and medical staff.

“…Currently, the Acuson AcuNav V catheter (Siemens Healthcare) is the only available ICE probe with real-time 3D imaging functionality. While first experience has been gathered with volume ICE in electrophysiology 4 and transcatheter aortic valve replacement, 5 this is to the best of our knowledge the first published PMVR procedure guided by volume ICE. Imaging by ICE provides very good spatial resolution.…”

“…The added value of 3D ICE over two-dimensional (2D) ICE includes the good visualization of the ridge between the LA appendage and the left pulmonary veins, which is very easy, uniformly successful, and excellent in resolution. 4 Furthermore, it enables real-time 3D documentation of target structures, facilitates interpretation of 3D structures, and may reduce procedure time. 4 As experience in other interventions suggests that tracking small structures such as thin wires, catheters, and devices with real-time 3D ICE is generally easier compared with 2D ICE, 6 this technique may facilitate precise positioning of the MitraClip in relation to the underlying pathology.…”

“…ICE technology has been limited to two-dimensional and color Doppler assessment of regurgitant jets alone and by restrictions as to where the catheter can be safely positioned. However, recent advances have enabled real-time three-dimensional/volume imaging [26], may facilitate more frequent use with better visualization and interrogation of the anatomy of interest, and likely associated increases in procedural success rates into the future [27].…”
