OBJECTIVE: Assesing the rate of cerebral microembolization (CM) during the convergent procedure (CP) for treatment of atrial fibrillation.
METHODS: A prospective study included 22 consecutive patients [age 58.9±6 years, 68.2% (15/22) male] that underwent hybrid CP for treatment of paroxysmal AF. Patients received intravenous heparin to reach the ACT of at least 300 seconds before the transseptal punctures. Magnetic resonance scans (diffusion weighted and FLAIR) were performed the day before and the day after the procedure. Presence of new cerebral ischaemic lesions was assessed.
RESULTS: Just one patient (4.5%, 1/22) had two new ischaemic cerebral lesions (diameter 1-2 mm) and was without any clinically detectable neurologic deficit.
CONCLUSIONS: Incidence of periprocedural CM in patients with paroxysmal AF undergoing CP is low.
