Results of the cryoballoon PVI
Out of a total of 204 enrolled PVs, all PVs were successfully isolated. Although temporary right phrenic nerve paralysis was observed in two patients during the cryoballoon ablation at the RSPV, the motion of the diaphragm fully recovered by the first out patient visit. A groin hematoma was observed in three patients. There were no other complications during the procedure including systemic embolic events such as cerebral and myocardial infarctions.
