Does saline-cooled radiofrequency catheter ablation improve termination of VT compared to standard radiofrequency catheter ablation in patients with infarct-related ventricular tachycardias?
Saline-cooled radiofrequency ablation shows greater efficacy for terminating infarct-related ventricular tachycardias compared to standard ablation, likely due to the creation of larger lesions.
Greater efficacy of cooled RF for terminating VT is consistent with the production of a larger lesion in human infarctions, which should facilitate successful ablation.
