Abstract: Introduction: Current techniques for cardiac ablation require extensive manual endocardial catheter manipulation by the operator, raising the risk for contact related safety events and contributing to operator fatigue. Furthermore, the quality of the resultant anatomical map and the integrity of ablation lesions are highly operator dependent. We evaluated a novel ablation system, using low intensity collimated ultrasound (LICU) to map and ablate in a non-contact, automated mode; we quantified the extent to which automation may reduce the need for direct operator catheter manipulation. Methods: PAF subjects in the VALUE study receiving PVI (n = 14) were treated. After minimal catheter manipulation, an automated 3D ultrasound scan of left atrial anatomy was performed followed by complete bilateral WACA lesion sets to electrically isolate the right and left PVs. The time required for each workflow step was recorded. These results were analyzed to calculate the proportion of time in which the operator spends in manual procedures compared to the time in which the system spends in an automated mode. Results: The mean proportion of manual vs automated time was 22 vs. 50%. The remaining balance of time (28%) was related to common clinical tasks not directly associated with the ablation. Compared to a typical fully manual case, the use of automation reduced the need for direct operator engagement by 69%. There were no contact-related or other SAEs (perforation, tamponade, pericarditis, effusion). Conclusions: Computer assisted LICU enables the use of automated techniques to both map and treat the left atrium, thus reducing requirements for direct operator engagement during the procedure. Reduced manual manipulation of the catheter may benefit patients by limiting the time in direct contact with endocardial tissue and the risk for contact-related safety events. Additional benefits may be derived from allowing the operator to focus on other aspects of patient safety rather than concentrate on catheter manipulation during the procedure. Abstract P372 Figure.
