ABSTRACT Background Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism initiation and maintenance fibrillation (AF) is stimulation from EGF‐identified focal sources that serve as driver sites fibrillatory conduction. consistency (EGFC) further quantifies concordance observed patterns, indicating a healthier substrate shows more organized propagation higher EGFC. Freedom AF (FFAF) recurrence has accordingly been shown to be in...
The goal of this study was to describe mapping and ablation severe arrhythmias during pregnancy, with minimum or no X-ray exposure. Treatment tachyarrhythmia in pregnancy is a clinical problem. Pharmacotherapy entails risk adverse effects unsuccessful some patients. Radiofrequency has been performed rarely, because fetal exposure potential maternal fetus complications. GROUP AND METHOD: Mapping 9 women (age 24-34 years) at 12-38th week pregnancy. Three had permanent junctional reciprocating...
Pulsed field ablation uses electrical fields to cause nonthermal cell death over several hours. Polarization-sensitive optical coherence reflectometry is an imaging technique that can detect changes in the tissue ultrastructure real time, which occurs when muscular damaged. The objective of this study was evaluate ability a polarization-sensitive system predict development chronic lesions based on acute birefringence during pulsed ablation. Superior vena cava isolation performed 30 swine...
Background/Objectives: Electrographic flow (EGF) mapping allows for the visualization and quantification of atrial fibrillation (AF) wavefront propagation patterns. EGF-identified sources were shown in randomized controlled FLOW-AF trial to significantly increase likelihood AF recurrence within 1 year if left unablated. consistency (EGFC) additionally measures stability observed patterns, such that patients with more organization have a healthier substrate lower recurrence. Source presence...
ABSTRACT Introduction Stability of catheter‐tissue contact in the robotic magnetic navigation (RMN) system is one key features that distinguishes this from manually guided catheters. Numerous studies have shown force (CF) controlled catheters as crucial for forming an optimal lesion duration application or power. Catheters used RMN lack a quantitative method intraoperative monitoring parameter. Our study aims to partially address gap scientific knowledge. Methods We conducted total 1200 CF...
ABSTRACT Introduction Catheter ablation (CA) is a preferred treatment for atrial fibrillation (AF), often outperforming antiarrhythmic medications in maintaining sinus rhythm and managing symptoms. One of the most important features any method, alongside its effectiveness, safety. Methods This study evaluates 180‐day all‐cause mortality rates post‐ablation using data from National Health Fund Poland (NHF‐P), encompassing over 99% AF CAs 100% deaths 2012 to 2019. Results Our analysis, which...
ABSTRACT Introduction Pulsed Field Cryoablation (PFCA) is a dual‐energy cardiac ablation modality consisting of short‐duration ultra‐low temperature cryoablation (ULTC) followed immediately by pulsed field (PFA) delivered from the same catheter. It hypothesized that PFCA may improve contact stability during PFA, while maintaining lesion depth and effectiveness ULTC. Methods PARALELL first‐in‐human multicenter study evaluating safety novel catheter system in patients with persistent atrial...
Data regarding long-term follow-up of radiofrequency catheter ablation (RFCA) accessory pathways (APs) in patients with Ebstein's anomaly (EA) are limited. The procedures challenging due to multiple or wide APs.Analysis was performed on clinical and periprocedural data EA referred the centre order perform AP. group consisted 22 (female 40.9%, mean age 33.6 ± 19.1 years). utilized electrocardiogram Holter monitoring.Twenty-two had 33 (8 APs, 11 broad AP). Twenty-nine different arrhythmias...
AF in WPW Syndrome. Aim : We aimed to characterize electrophysiological properties of pulmonary veins (PVs) patients with Wolff–Parkinson–White (WPW) syndrome and atrial fibrillation (AF), compare them those without AF. Methods Results: A total 31 (mean age 40 ± 15 years, 23 males) were recruited: 16 (AF group) (controls) a history The basic (EPS) echocardiographic data not different between the 2 groups. Effective refractory periods (ERPs) PVs significantly shorter group compared controls:...
Introduction: Measuring the postpacing interval (PPI) and correcting for tachycardia cycle length (TCL) is an important entrainment response (ER). However, it may be impossible to measure PPI due electrical noise on mapping catheter. To overcome this problem, 2 alternative methods assessment of ER have been proposed: N+1 difference (N+1 DIFF) PPIR method. PPI‐TCL (PPI − TCL) correlates very well with assessed by new methods, but agreement TCL was established only in relation Moreover, not...
Background Atrial fibrillation (AF) is a common complication in patients with hypertrophic cardiomyopathy (HCM) and may contribute to high cardiovascular morbidity mortality. Therefore, it important assess parameters associated AF HCM patients. Hypothesis The aim of the study was evaluate prevalence investigate risk factors for AF. Methods Five hundred forty‐six aged below 65 were included into analysis. Clinical echocardiographic analyzed. Results In 141 (25.8%) episodes recorded. following...
Mitral valve defects are frequently associated with atrial arrhythmias. Percutaneous or surgical mitral valveprocedures may reverse adverse haemodynamic consequences of the valvular defect but have little effect on arrhythmiaitself. With safety concerns and few outcome data, role catheter ablation in these patients has not been established yet.To assess efficacy complex left arrhythmias after percutaneous orsurgical procedures.We studied 14 (mean age 55 ± 11 years; 9 females) a history...
