ObjectiveTo investigate the effectiveness and safety of valve surgery in combination with cryoablation in the treatment of atrial fibrillation.MethodsFifty patients who needed to undergo valve surgery because of heart valve disease and sixty-five patients who needed to undergo valve surgery in combination with cryoablation were selected as the research subjects. The perioperative technical characteristics, postoperative curative effect and complications were compared between the two different treatment modalities in our hospital between October 2013 and November 2015.ResultsNo significant differences were observed between the two groups in valve surgery mode, valve type and postoperative length of hospital stay (P>0.05), but the duration of extracorporeal bypass and aorta occlusion of the observation group was longer than that of the control group (P<0.05). The 3-month, 6-month and one-year atrial fibrillation cardioversion rates of patients in the observation group were superior to those of the control group, and the differences were notable (P<0.05). The improvement of left atrial diameter of the observation group was also superior to that of the control group (P<0.05). The incidence of postoperative complications of the two groups had no significant difference (P>0.05).ConclusionValve surgery in combination with cryoablation has favorable short-term clinical effect in the treatment of heart valve disease in combination with atrial fibrillation, which is worth promotion.
