Increased risk of thromboembolic events in adult congenital heart disease patients with atrial tachyarrhythmias

ACHD patients with atrial tachyarrhythmias and even those with low or intermediate risk as indicated by the CHADS2 or CHA2DS2-VASc score had a higher risk of thromboembolic events. Therefore, anticoagulation should be considered earlier than in the general population in patients with risk factors of age ≥ 60 years, vascular disease, or persistent AF.
