Complications
HFS within the CS inadvertently captured the ventricle and induced
ventricular fibrillation in one patient (Case 7, Figure 4). We
immediately performed external electrical defibrillation then
successfully terminated the ventricular fibrillation.
Another patient developed the right phrenic nerve injury (Case 4). It
was attributable to the RF application during SVC isolation and
eventually resolved over two years after the procedure.
