After ablation follow-up
Intravenous implantable cardioverter-defibrillator or subcutaneous-ICD were implanted for four cases with periaortic VTs as secondary prevention. The two patients who underwent VT ablation have not experienced a recurrence of periaortic VTs till now (1 and 4.3 years free from sustained VT events after the ablation, respectively). The other patient with double valve replacement developed recurrence of periaortic VTs 1.4 years after the first incidence, even while on amiodarone. In response to this, we increased the dose of beta-blockers, which successfully suppressed periaortic VTs till now.
