Background: Silent cerebral ischemic lesions (SCILs) detected by magnetic resonance imaging (MRI) can precede symptomatic stroke, the risk of which is increased five-fold in atrial fibrillation (AF) patients. In our study, we aimed to evaluate the initial incidence of SCILs in the population of patients referred for ablation due to symptomatic AF and to identify possible risk factors.
Methods: A total of 110 patients, with a mean age (SD) of 59.
Article Synopsis
- Pulsed field ablation (PFA) is a new technique for heart tissue treatment that targets heart cells directly without damaging nearby tissues, but using it with mechanical heart valves can be tricky due to potential interference.* -
- This study involved 30 patients with mechanical heart valves undergoing PFA for atrial fibrillation, and it found no major complications, with normal valve function post-procedure.* -
- While PFA seems safe for patients with mechanical valves, careful management of the catheter is crucial to prevent electromagnetic interference that could affect the treatment.*
Introduction: Atrial fibrillation (AF) is the most common arrhythmia, increasing the risk of stroke and all-cause mortality. Pulmonary vein isolation (PVI) with cryoballoon ablation (CBA) is a widely accepted approach for invasive treatment of patients with AF. CBA effectiveness is considered to be strongly dependent upon the anatomy of pulmonary veins, mainly the ovality of pulmonary veins' ostia.

We analyzed time-dependent changes in procedural parameters, acute success, complication rates, and long-term outcomes during our initial experience with multipolar phased-radiofrequency (RF) ablation.

Methods And Results: We analyzed acute effect and long-term follow-up of second-generation cryoballoon ablation, performed as a repeat procedure after an index radiofrequency vs cryoballoon ablation.
