Incidence and risk factors of post-operative arrhythmias and sudden cardiac death after atrioventricular septal defect (AVSD) correction: Up to 47Â years of follow-up

There is good long-term survival after AVSD correction and incidence of SCD is low. Non-syndromic AVSD and cAVSD are independent risk factors for early post-operative SVTs. Non-syndromic AVSD patients have significant more early 3rd degree AVB and late post-operative SVTs. Non-syndromic patients with partial AVSD who have undergone reoperation have a significant higher risk of pacemaker implantation.
