Complex Fractionated Atrial Electrogram

The OneMap™ tool, a new software feature of the EnSite Velocity™ System, and the new Inquiry™ AFocus™ II double loop duodecapolar diagnostic catheter (DDC) were created to provide faster data collection to efficiently deal with complex arrhythmias such as persistent atrial fibrillation ablation (AF). Our study was performed to compare acquisition criteria, time needed to create the maps, number of collected points, relevance of complex fractionated atrial electrogram (CFE) mapping and correlation between CFE maps with the new DDC and a 4mm irrigated ablation catheter (ABL), Therapy™ Cool Path™ Duo, using the OneMap tool. Ten patients undergoing persistent AF ablation were enrolled. With the DDC, more points were collected (485±173 versus 183±37) and the time needed to create CFE maps was shorter (12±4 versus 24±2 minutes). There were 39 zones detected with the DDC against 35 with the ABL. The correlation between the maps was 80%; however, four additional regions were detected with the DDC (an 11% increase). In conclusion, the Inquiry AFocus II DDC is a feasible, fast and accurate tool for automatic CFE mapping using OneMap.
