Procedural data
In 23 procedures, mean procedural time was 102.7 + 25.3 min, and mean left atrial dwelling time was 78.8 + 19.8 min. Mean radiation time was 25.3 + 8.4 min, median radiation dose was 33.0 (8.9, 55.3) mGy, and median dose area product (DAP) was 5.2 (4.7, 10.0) Gy*cm2. All of the PVs achieved bidirectional block when rechecked at the end of the procedure. One temporary PNI occurred during cryoablation of RSPV and spontaneously resolved upon cessation of cryoablation. No major complication was observed during the peri-procedural period.
