Cryothermal energy demonstrates shorter ablation time and lower complication rates compared with radiofrequency in surgical hybrid ablation for recurrent ventricular tachycardia
Authors' conclusion
Hybrid surgical VT ablation with cryothermal or radiofrequency energy demonstrated similar efficacy outcomes.
