Effect of Pulsed Field Timing Sequence and Electrode Cooling on Ablation Safety and Efficacy Surrogates: A Preclinical Study.
BACKGROUND The variable loop circular catheter has been shown to be a safe, effective pulsed field ablation catheter for atrial fibrillation treatment. After the commercial launch of the initial waveform (Seq1), a new waveform (Seq230 mL/min) was developed that reduces electrode surface temperature and ablation deliver...
