Outcomes of ablation with the FARAPULSE PFA System – a nonthermal treatment in which electric fields selectively ablate heart tissue – will be compared to outcomes following use of anti-arrhythmic drug (AAD) therapy, which is commonly prescribed for patients living with persistent AF. The company now anticipates U.S.
a global leader in cardiac arrhythmia treatment and part of Johnson & Johnson MedTechi , revealed findings from a company-funded study of real-world data. Biosense Webster's zero fluoroscopy workflow is the first and only such workflow available in a radiofrequency (RF) cardiac ablation device.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Epicardial radiofrequency catheter ablation (RFCA) of idiopathic ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) is challenging because of the anatomic barriers.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. We investigate whether additional linear ablation from the superior vena cava to the right atrial septum and cavotricuspid isthmus ablation improves the rhythm outcome of patients with persistent AF undergoing cryoballoon PVI (Cryo-PVI).METHODS:In
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:It is difficult to identify patients with atrial fibrillation (AF) most likely to respond to ablation. There remains an urgent need to develop procedural predictors of long-term AF ablation success.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:High-power short-duration ablation has shown impressive efficacy and safety for pulmonary vein isolation (PVI); however, initial efficacy results with very high power short-duration ablation were discouraging. No complications occurred.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Patients were randomly assigned to either the PVI+SVC ablation group or the PVI-only group. CONCLUSIONS:The addition of SVC ablation to PVI did not enhance freedom from atrial tachyarrhythmia at 12 months, and it led to increased complications.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. The first dose of the study drug was administered within 4 hours before ablation. mg twice daily or placebo for 10 days. mg twice daily or placebo for 10 days.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Background:Pulsed field ablation (PFA) has emerged as an alternative to radiofrequency ablation. However, data on focal point-by-point PFA are scarce.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Power-controlled radiofrequency ablation with irrigated-tip catheters has been the norm for ventricular ablation for almost 2 decades. Four and one of these sets of parameters were further tested in phases II and III, respectively.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Epicardial approach in ventricular tachycardia (VT) ablation is still regarded as a second-step strategy, due to the risk of complications. The epicardial approach was considered useful if epicardial ablation was performed after epicardial mapping.
Circulation, Ahead of Print. In addition, new recommendations addressing atrial fibrillation and thromboembolic risk assessment, anticoagulation, left atrial appendage occlusion, atrial fibrillation catheter or surgical ablation, and risk factor modification and atrial fibrillation prevention have been developed.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Sequential application of radiofrequency with pulsed field (PF) ablation may increase lesion depth while preserving the advantages of PF. Ablations were performed with a force-sensing 3.5-mm
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:The effect of contact force (CF) on lesion formation is not clear during pulsed field ablation (PFA). Further studies are required to evaluate the best PFA ablation settings to achieve transmural lesions.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Background:Effects of contact force (CF) on lesion formation during pulsed field ablation (PFA) have not been well validated. mm ablation electrode and CF sensor (TactiCath SE, Abbott) was connected to a PFA system (CENTAURI, Galvanize Therapeutics).
Spatial relationship of sites for atrial fibrillation drivers and atrial tachycardia in patients with both arrhythmias July 2017 International Journal of Cardiology 248(3) AF begets AF. In contrast to other tachycardias, with atrial fibrillation (AF), the focus is often speculative, and ablation attempts are made accordingly.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. To summarize, 5 cases had prior ablation with 2 previously misdiagnosed as supraventricular tachycardia. Ablation targeting the mid-septal left septal fascicle and P1 to P2 connection sites successfully eliminated left posterior FVT.
Circulation, Volume 150, Issue Suppl_1 , Page A4143083-A4143083, November 12, 2024. She remained in flutter despite diuresis, rate control with metoprolol and digoxin, cardioversion, and ablation. She underwent a cesarean section at 32 weeks given ongoing arrhythmia and heart failure symptoms.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. According to CS, pacing MI ablation was incomplete in 9 patients, in whom the analysis indicated persistent VOM connection. MI block was verified using conventional CS pacing.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Louis, MO) utilizes an augmented reality headset (Magic Leap, Plantation, FL) to display a real-time 3-dimensional electroanatomic map, catheter locations, and ablation catheter contact force data to the electrophysiologist using a hands-free interface.
The guideline was jointly published today in the Journal of the American College of Cardiology and Circulation. Atrial fibrillation, or AFib, is the most common type of heart rhythm disorder (arrhythmia), affecting over 6 million Americans, and the number is expected to double by 2030. This is a complex disease.
Circulation: Arrhythmia and Electrophysiology, Volume 17, Issue 12 , Page e013385, December 1, 2024. BACKGROUND:Left bundle branch pacing (LBBP) has emerged as a safe and effective alternative to right ventricular pacing.
Circulation: Arrhythmia and Electrophysiology, Volume 16, Issue 11 , Page e012191, November 1, 2023. Ablation was acutely successful in 13 of 14 patients with recurrence in 3. One procedure was complicated by complete heart block after ablation of a high-risk midseptal AP.
The patient was started on amiodarone, anticoagulation, and metoprolol, and scheduled for atrial flutter ablation. He underwent ablation in the EP Lab. Reverted to atrial fibrillation with RVR while in the hospital 3 times and needed cardioversion. Sinus tachycardia does not go this fast.
