Key result
Radiofrequency catheter ablation without prior ICD inactivation caused no device dysfunction and maintained excellent intracardiac ECG registration during energy delivery.
Why the study?
Does right ventricular radiofrequency catheter ablation without prior ICD inactivation cause device dysfunction in a patient with frequent ventricular tachycardia?
Does right ventricular radiofrequency catheter ablation without prior ICD inactivation cause device dysfunction in a patient with frequent ventricular tachycardia?
Right ventricular radiofrequency catheter ablation may be performed without prior ICD inactivation without causing device dysfunction.
Answers are grounded in this paper and cite their sources.
May support ablation without ICD inactivation in select VT cases; leaves open need for prospective validation before broader adoption.
Right ventricular radiofrequency catheter ablation was performed in an ICD patient with frequent ventricular tachycardia without prior inactivation of the device. The registrations of intracardiac ECG and marker channel were excellent during energy delivery: the surface ECG was affected. The device did not show dysfunction during and after energy delivery.
