Abstract

The article presents two clinical cases of delayed restoration of the sinus rhythm in patients with long-term persistent atrial fibrillation after the procedure of thoracoscopic radiofrequency fragmentation of the left atrium. The necessity of continuing attempts to restore the sinus rhythm up to the end of the "blind period" (90 days) is discussed.
