Background characteristics and clinical outcome
The baseline and procedural characteristics in 62 patients were given in
Table 1. Structural heart disease (SHD) was found in 11 (15%) patients,
and median AF history of 8 months was noted. An average procedure time
was 125 minutes with RF time and energy for PVI of 10±3 min and 28±8 kJ,
respectively. All patients had undergone superior vena cava isolation
after PVI. Complication occurred in only one patient: an acute right
phrenic nerve injury was identified following completion of the
right-sided PVI before superior vena cava isolation. This was almost
fully recovered after 6-month follow up.
