Atrial fibrillation ablation: Limitations of pulmonary vein ablation catheter technology.
We read with interest the paper by Koźluk et al. [1], which brings several points about multi-electrode duty-cycled radiofrequency ablation: — The outcome in patients with paroxysmal atrial fibrillation (AF) was lower when compared to 1and 5-year follow-up after single cryoballoon ablation procedure performed with higher follow-up regime (7and not 1-day Holter ECG) [2]. Most triggers originate ...
متن کاملPulmonary Vein Stenosis Complicating Radiofrequency Catheter Ablation
The aim of this study is to characterize the clinical manifestations and features of pulmonary vein stenosis (PVS) by retrospectively analyzing clinical data of patients in addition to reviewing the literature simultaneously to improve the understanding of PVS complicating radiofrequency catheter ablation and to provide evidence for early diagnosis and timely treatment. Clinical, imaging, and f...
متن کاملPrevalence, characteristics, and predictors of pulmonary vein narrowing after isolation using the pulmonary vein ablation catheter.
BACKGROUND The risk of pulmonary vein narrowing (PVN) after pulmonary vein isolation, using a novel multi-electrode ablation catheter, is unknown. METHODS AND RESULTS Left atrial volume and PV diameters were compared by computed tomography (CT) before and 3 months after pulmonary vein isolation using duty-cycled phased radio frequency energy (2:1 or 4:1 bipolar/unipolar ratio) in 50 patients....
متن کاملFirst-in-human case of repeat pulmonary vein isolation by targeting visual interlesion gaps using the direct endoscopic ablation catheter after single ring pulmonary vein isolation
Gaps between radiofrequency (RF) ablation lesions are the culprits for failed pulmonary vein isolation (PVI) leading to recurrent atrial arrhythmias. The ability to directly visualize in real time and eliminate interlesion gaps may improve the success of RF ablation by achieving contiguous linear ablation lesion sets. We aimed to describe to the best of our knowledge the first reported clinical...
متن کاملMultielectrode Pulmonary Vein Isolation Versus Single Tip Wide Area Catheter Ablation-Paroxysmal Atrial Fibrillation
In the past decade, catheter ablation of atrial fibrillation (AF) has evolved as one of the most frequently performed procedures in tertiary arrhythmia centers worldwide. With the observation of the actively firing trigger originating from within the pulmonary veins (PVs), ablation strategies have focused at least in paroxysmal AF patients on complete isolation of the PVs. Several different abl...
