Touch-up rate and right PNI during cryoballoon pulmonary vein isolation. The touch-up rate was higher for AFA-CB than POLARx-CB, and the difference was significant for the RIPVs. The incidence of right PNI was significantly higher for POLARx than AFA-CB. Phrenic nerve injury recovered more quickly with AFA than POLARx; however, the difference was not statistically significant. LCPV, left common PV; LI(S)PV, left inferior (superior) PV; PNI, phrenic nerve injury; pts, patients; PV(I), pulmonary vein (isolation); RI(S)PV, right inferior (superior) PV.
