Abstract：Objective To investigate the efficacy and safety of high-power circumferential pulmonary vein isolation(CPVI)combined with high-power superior vena cava(SVC)isolation in treatment of paroxysmal atrial fibrillation(PAF).Methods PAF patients(n=100)were chosen and divided into control group given only high-power CPVI and test group given routine high-power SVC isolation based on high-power CPVI(each n=50).The time of operation,AF recurrence rate 1 y later and incidence of complications were compared between 2 groups.Results The operation time was longer(P<0.05),and AF recurrence rate 1 y later was lower(P<0.05)in test group than those in control group.There was 1 case of pericardial effusion in each group,and there were no injuries of sinus node and phrenic nerve in 2 groups.Conclusion The high-power SVC isolation combined with high-power CPVI is safe in PAF treatment,and can effectively reduce AF recurrence rate 1 y after the operation compared with only high-power CPVI.
