Abstract Background Hyperuricemia (HU) has been reported to be associated with a high incidence of atrial fibrillation (AF). However, the relationship between HUA and recurrent AF after catheter ablation (CA) is unclear. Methods Four hundred consecutive patients (paroxysmal/persistent [PAF/PsAF]: 200/200) who underwent initial CA were retrospectively enrolled. HU was defined as serum uric acid (SUA) level >7.0 mg/dL. We measured SUA levels 1 day before (pre‐CA) month (post‐CA). A...
Objectives One of the mechanisms early recurrence atrial fibrillation (ERAF) after AF ablation is considered to be inflammatory reaction tissue. The aim this study compare clinical significance ERAF at each stage for true between cryoballoon (CB) and radiofrequency (RF) ablation. Methods Among 798 paroxysmal patients who underwent an initial ablation, 460 (CB, n = 230; RF, 230) were selected by propensity score matching. Very (VERAF), ERAF-1M, ERAF-3M defined as 0–2, 3–30, 31–90 days more...
Pulmonary vein stenosis (PVS) after PV isolation (PVI) for atrial fibrillation (AF) is a severe complication that requires angioplasty. This study aimed to compare the reduction of cross-sectional area (PVA) and incidence PVS cryoballoon (CB)-PVI, hot balloon (HB)-PVI, or laser (LB)-PVI.
Abstract While phrenic nerve palsy (PNP) due to cryoballoon pulmonary vein isolation (PVI) of atrial fibrillation (AF) was transient in most cases, no studies have reported the results long-term follow-up PNP. This study aimed summarize details and PNP after ablation. A total 511 consecutive AF patients who underwent ablation included. During right-side PVI, diaphragmatic compound motor action potential (CMAP) reduced 46 (9.0%) occurred 29 (5.7%) (during right-superior PVI 20 right-inferior...
Pulmonary vein (PV) stenosis after atrial fibrillation (AF) ablation is rare; however, it remains a serious complication. PV angioplasty reportedly an effective therapy; dedicated device for has not been developed, and the detailed procedural methods remain undetermined. This study describes symptoms, indications, treatment strategies, long-term outcomes AF ablation.
Abstract Background Currently, two types of cryoballoon (CB) systems are available for catheter ablation atrial fibrillation (AF). Since the POLARx (Boston Scientific) is softer during freezing than Arctic Front Advance Pro (AFA‐Pro; Medtronic), it tends to go more deeply into pulmonary vein (PV), risking PV stenosis. Methods Ninety‐one patients underwent initial CB paroxysmal AF (AFA‐Pro 56; 35). Twenty‐six from each group were extracted using propensity score matching. The cross‐sectional...
Abstract Background The presence of heart failure (HF) has been associated with poorer outcomes in patients undergoing catheter ablation (CA) for atrial fibrillation (AF). However, the effectiveness CA amongst subset tachycardia‐induced cardiomyopathy (TIC) remains poorly defined. Methods and Results In a retrospective analysis we compared first‐time persistent AF cohort previously diagnosed TIC (n = 45; age 58 ± 8 years; 91% male) to those structurally normal hearts (non‐TIC; n 440; 55 9...
It was previously reported, based on a retrospective study, that preliminary removal of air bubbles in heparinized saline water with extracorporeal balloon inflation reduced the incidence asymptomatic cerebral embolism (ACE). The present study aims to compare ACE between conventional and pre-inflation method during cryoballoon ablation prospective randomized controlled study.A total 98 atrial fibrillation patients were enrolled into groups. Patients group received massaging before inserted...
Catheter ablation for atrial fibrillation (AF) in patients with tachycardia-bradycardia syndrome (TBS) can be a major therapeutic option to replace permanent pacemaker implantation (PMI). However, the very long-term outcome of more than 15 years these has not been elucidated.From 2002 2008, 25 consecutive TBS (62 ± 7.9 old, 68% male) both AF and symptomatic sinus pauses (>3.0 s) were performed radiofrequency ablation. These followed 2.7 years.The median longest pause before procedure was 6.0...
The optimal ablation strategy for persistent atrial fibrillation (PsAF) remains to be defined. We sought compare very long-term outcomes between linear and electrogram (EGM)-guided PsAF. In a retrospective analysis, arrhythmia-free survival compared two propensity-score matched cohorts, one with pulmonary vein isolation (PVI) including roof/mitral isthmus line (LINE-group, n = 52) PVI EGM-guided (EGM-group; 52). Overall, 99% of patients underwent successful PVI. Complete block following was...
Key Teaching Points1.Although inferior vena cava (IVC) is known as a possible source of non-PV foci in AF patients, the prevalence very low.2.Although some previous cases anatomically demonstrated origin trigger from IVC using three-dimensional (3-D) mapping system, definition border between and atrium was unclear.3.This case continuous ectopic bigeminy definitely originating tiny area within by beats both with without conduction to 3-D system. 1.Although
We report a case of atrial fibrillation (AF) recurrence after pulmonary vein isolation, which patient had AF trigger in the superior vena cava (SVC) near sinus node (SN). The ultra-high-resolution mapping revealed that SN located within SVC and activation from to propagated both septal lateral direction, then upward with circumventing spontaneous conduction block identified just above (upper hemisphere). successfully isolated including ectopic origin at same level as by utilizing line around...
We report a case of atrial fibrillation with frequent monomorphic premature contractions (APCs) in which P-wave morphology was negative II, III, and aVF positive I aVL leads. After pulmonary vein isolation using cryoballoon, high-resolution electroanatomical mapping revealed ectopic beats from the posteroseptal area within inferior vena cava (IVC) concealed bigeminy. Catheter ablation just above focus eliminated APC residual dissociated activity inside IVC. This is first to reveal continuous...
