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.
