Is discontinuation of warfarin treatment safe after pulmonary vein isolation in high-risk patients with atrial fibrillation?
Discontinuation of warfarin after pulmonary vein isolation is unsafe in high-risk patients, particularly those with a history of ischemic stroke.
These findings indicate that discontinuation of warfarin treatment after PVI is not safe in high-risk patients, especially those who have previously experienced an ischemic stroke.
Själander et al. (Mon,) studied this question.
