The operative mortality and early postoperative morbidities, including bleeding reoperation, stroke, permanent pacemaker implantation and acute kidney injury were comparable between the groups. The overall survival showed no differences between the groups. However, the cumulative incidence of new-onset late ischaemic stroke was significantly lower in group A than group N in propensity score-matched patients [2.3 vs 3.5 per 100 patient-years, adjusted hazard ratio (95% confidence interval) 0.64 (0.43\u20130.96), Group A versus Group N, respectively]. The cumulative incidence of other morbidities such as reoperation, permanent pacemaker implantation and progression to chronic renal failure showed no difference between groups.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The incidence of late ischaemic stroke was significantly lower when concomitant SA was performed during isolated AVR in patients with underlying AF.
