Pulmonary vein isolation durability and lesion regression in patients with recurrent arrhythmia after pulsed-field ablation

Journal of interventional cardiac electrophysiology, 2023
A novel multipolar pulsed-field ablation (PFA) catheter has recently been introduced for pulmonary vein isolation (PVI). Pre-market data showed high rates for PVI-durability during mandatory remapping studies.

Long‐Term Outcomes of Pulmonary Vein Isolation in Patients With Brugada Syndrome and Paroxysmal Atrial Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Pharmacological treatment of atrial fibrillation (AF) in the setting of Brugada syndrome (BrS) is challenging. In addition, patients with BrS with an implantable cardioverter‐defibrillator (ICD) might experience inappropriate shocks for fast ...

Preclinical assessment of the feasibility, safety and lesion durability of a novel ‘single-shot’ pulsed field ablation catheter for pulmonary vein isolation

Europace, 2023
Aims Single-shot pulmonary vein isolation can improve procedural efficiency. To assess the capability of a novel, expandable lattice-shaped catheter to rapidly isolate thoracic veins using pulsed field ablation (PFA) in healthy swine. Methods and results

Rate‐dependent and unidirectional conduction block between the left pulmonary vein and left atrium after catheter ablation for atrial fibrillation

Journal of Arrhythmia, 2020
A 77‐year‐old woman with symptomatic paroxysmal atrial fibrillation (PAF) underwent pulmonary vein isolation (PVI), but subsequently experienced recurrence.

Spontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation [PDF]

Europace, 2004
A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.

Pulsed field ablation selectively spares the oesophagus during pulmonary vein isolation for atrial fibrillation

Europace, 2021
Aims Extra-atrial injury can cause complications after catheter ablation for atrial fibrillation (AF). Pulsed field ablation (PFA) has generated preclinical data suggesting that it selectively targets the myocardium.

Multicenter retrospective database evaluation of Takotsubo syndrome in subjects undergoing catheter ablation for atrial fibrillation

Journal of Arrhythmia, 2023
Background Intracardiac catheter ablation for atrial fibrillation with pulmonary vein isolation may result in Takotsubo syndrome (TS), but the frequency, predisposing factors (age, sex, mental health disorders), and outcomes are currently unknown.

Findings from repeat ablation using high-density mapping after pulmonary vein isolation with pulsed field ablation

Europace, 2022
Aims Pulsed-field ablation (PFA) can offer a novel perspective for atrial fibrillation (AF) ablation. We aimed to characterize the incidence of pulmonary vein (PV) reconnection, types of recurrent atrial tachyarrhythmia (ATa) and lesion quality after PFA-

Semi-urgent pulmonary vein isolation using cryoballoon for haemodynamically unstable atrial fibrillation storm in a patient with low cardiac output syndrome: a case report

BMC Cardiovascular Disorders, 2020
Background Atrial fibrillation and heart failure are common coexisting conditions requiring hospitalisation for heart failure and death. Pulmonary vein isolation is a well-established option for symptomatic atrial fibrillation and for atrial fibrillation

, 2013
Aim: To evaluate the effectiveness of two different strategies using radiofrequency catheter ablation for redo procedures after cryoablation of atrial fibrillation. Methods: Thirty patients (paroxysmal atrial fibrillation: 22 patients, persistent atrial
