In vitro evaluation of ice-cold saline irrigation during catheter radiofrequeny ablation
Original language description
IntroductionIrrigated radiofrequency (RF) catheters allow tissue-electrode interface cooling, decreasing thrombus risk while enabling higher RF power delivery. The impact of irrigation with ice-cold saline (ICS) instead of conventional ambient-temperature saline (ATS) on lesion formation is unknown. Methods and ResultsWe performed 120 RF ablations in vitro on porcine left ventricles, using ICS (<5 degrees C) or ATS (21 degrees C) irrigation. For ICS irrigation, the irrigation circuit was cooled externally to maintain delivery of cooled saline at the catheter's tip. We applied 20g of contact force, and delivered 20 W (irrigation 8 or 17 mL/min) or 30 W (irrigation 17 or 30 mL/min) RF power. Temperatures at tissue-electrode interface and 3-mm depth wereassessed by fluoroptic probes. Lesion dimensions were assessed. ICS irrigation cooled the tissue-electrode interface better than ATS (53.9 9.6 degrees C vs. 63 +/- 11.4 degrees C, P < 0.001). Temperatures at 3-mm depth were similar at 30
