Primary adverse events occurred in 2.5% of patients (two pericardial effusions or tamponade, one hematoma), Reddy et al note, adding that there was one transient ischaemic attack. The safety and efficacy of pulsed field ablation (PFA) in Patients with Paroxysmal Atrial Fibrillation (PAF) will be studied using ring-shaped pulsed field ablation catheter. This energy source generates rapidly resolving micro gas bubbles immediately after a pulse delivery.21 The theoretical possibility of these gas bubbles obstructing capillary blood flow causing organ ischemia and cerebral micro-emboli was not been observed in this clinical experience. Pulsed electric field is a novel energy source by which high-voltage electric pulses are used to create irreversible electroporation that could potentially break the trade-off between effective lesions and collateral damage and substantially improve risk-benefit ratios in atrial fibrillation (AF) ablation. This must be kept in mind as newer PFA technologies make their way into the clinical realm. Microporation of tissue for delivery of bioactive agentsMicroporation of tissue for delivery of bioactive agents . . . Results 41 Patients, median age 69 (interquartile range 62-73) years, 24% female, 56% persistent AF, underwent first PVI by PFA. Pulmonary vein isolation (PVI) with a "single-shot" pulsed-field ablation (PFA) catheter results in excellent PVI durability and acceptable safety with a low one-year rate of atrial arrhythmia recurrence in paroxysmal atrial fibrillation (AF) patients, according to data pooled from three clinical trials. 03925319, In vitro diagnostics expands reach to meet pent-up demand for other diseases and better position manufacturers for market volatilities, says GlobalData, NeuroPaces RNS system may prove to be an essential option to treating idiopathic generalised epilepsy at the source, says GlobalData, Singapore to focus on preventive healthcare through Healthier SG, says GlobalData. 2 - Reddy VY, Dukkipati SR, Neuzil P, et al. This design allows for circumferential PV ostial and antral coverage (Figure 3). Secondary Outcome Measures : As PFA is a novel form of ablation which uses electrical fields to ablate cardiac tissue, the authors note that there is currently limited data on assessing the safety of this ablation method in humans. Welcome any comments and/or testimonies. While pain relief may last longer with continuous current radiofrequency ablation (up to two years), the risk of complications increases. The author also noted that before the procedure, a full baseline evaluation was carried out on all patients. IMPULSE and PEFCAT studies are prospective, single-arm safety and feasibility trials performed at two sites (Homolka Hospital, Prague, Czech Republic, and Centre Hospitalier Universitaire de Bordeaux, Bordeaux, France), while PEFCAT II study is a prospective, single-arm feasibility trial performed at two sites (Homolka Hospital, Prague, Czech Republic, and CHU Split, Split, Croatia). Almost one in 200 patients die early after AF ablation in Adagio Medical announces patient enrolment in PARALELL trial, Two decades of development in AF treatment and education, New data underpin drive towards earlier AF ablation strategies, Q-FFICIENCY trial shows promise for temperature-controlled ablation. United States: 2020 Sep 1;76(9):1068-1080. doi: 10.1016/j.jacc.2020.07.007. Background: PVI with a "single-shot" PFA catheter results in excellent PVI durability and acceptable safety with a low 1-year rate of atrial arrhythmia recurrence. The presenter will offer his thoughts on where the field may be headed in the next 5-10 years. Before The 1-year Kaplan-Meier estimates for freedom from any atrial arrhythmia for the entire cohort and for the optimized biphasic energy PFA waveform cohort were 78.5 3.8% and 84.5 5.4%, respectively. Pulsed Field Ablation in Patients With Persistent Atrial Fibrillation. 155 North Wacker Drive, Suite 4250, Chicago, IL 60606 12-month ablation success rate of atrial fibrillation is defined by ECG data (including ECG and 24-hour dynamic electrocardiogram (Holter)) during the effective evaluation period (blanking period to the end of 12-month follow-up), without recording AF, AFL or AT (Arrhythmia monitoring device 30 seconds). It's supposed to take far less time and is more accurate in finding and eliminating aberrant cells and has a better success rate. Monophasic waveforms typically cause significant muscular activation, mandating the use of general anesthesia and neuromuscular paralysis. MeSH 2021 May;7(5):628-629. doi: 10.1016/j.jacep.2021.03.007. J Interv Card Electrophysiol. At one year, this translated to low rates of AF and other atrial arrhythmia recurrence. Pulsed field ablation for pulmonary vein isolation: real-world experience and characterization of the antral lesion size compared with cryoballoon ablation.
