“…In CBA, a refrigerant is used to cool the balloon tip of the ablation catheter after inflation to produce encircling lesions at the antral level of the pulmonary veins, compared to point-by-point ablation utilized by RFA. When compared to RFA, CBA has been demonstrated to be of similar efficacy [ 25 ], with second-generation cryoballoon technology potentially reducing the rates of recurrence after 12 months [ 26 ]. Current generation cryoballoon catheters are available in two different fixed-balloon sizes, whereas the balloon of the LB catheter is adjustable in size.…”

Catheter-based ablation techniques have a well-established role in atrial fibrillation (AF) management. The prevalence and impact of AF is increasing globally, thus mandating an emphasis on improving ablation techniques through innovation. One key area of ongoing evolution in this field is the use of laser energy to perform pulmonary vein isolation during AF catheter ablation. While laser use is not as widespread as other ablation techniques, such as radiofrequency ablation and cryoballoon ablation, advancements in product design and procedural protocols have demonstrated laser balloon ablation to be equally safe and effective compared to these other modalities. Additionally, strategies to improve procedural efficiency and decrease radiation exposure through low fluoroscopy protocols make this technology an increasingly promising and exciting option.
