Introduction:
Some reports have described superior vena cava isolation (SVCI) by the pentaspline pulsed-field ablation (PFA) catheter. However, this report presents a case series of superior vena cava (SVC) fibrillation successfully treated using a circular multielectrode array PFA catheter.
Methods:
We performed SVCI using a PulseSelect PFA catheter (Medtronic) in 11 cases. SVCI was performed when the earliest activation during ectopy was inside the SVC. In the second session, SVCI was routinely performed if the myocardial sleeves were of sufficient length.
Results:
The mean number of PFA deliveries was 7.8 ± 2.1 applications. Short-term success of SVC isolation was achieved in all patients. Importantly, no cases of sinus node dysfunction or persistent phrenic nerve palsy were observed in this study.
Conclusions:
A circular multielectrode array PFA catheter is useful and safe for treating non-pulmonary vein foci triggered by the SVC.
