Pulmonary vein isolation ablation is a minimally invasive procedure to treat atrial fibrillation (Afib). Ablation therapy uses hot or cold substances to create scar tissue. The scars disrupt abnormal electrical signals that cause atrial fibrillation. This procedure may be right for you if other arrhythmia treatments aren’t successful.

Jan 9, 2024 · Pulmonary vein isolation is a treatment for an irregular heart rhythm called atrial fibrillation (AFib). It is a type of cardiac ablation. Cardiac ablation uses heat or cold energy to create tiny scars in the heart. The scars block irregular electrical signals and restore a …

Feb 20, 2023 · In patients with recurrent AF despite durable PVI, no ablation strategy used alone or in combination during the redo procedure appears to be superior in improving arrhythmia-free survival. Left atrial size is a significant predictor of ablation outcome in this population.

Pulmonary vein isolation (PVI) is the standard ablation technique used to treat atrial fibrillation (AF) and currently has a class 1 recommendation for treatment of symptomatic AF when antiarrhythmic medication has failed or patients do not tolerate it. 1 Despite evidence-led indications and previous studies showing that ablation reduces the ...

What is pulmonary vein isolation (PVI) ablation? Pulmonary vein isolation is a procedure used to stop abnormal electrical signals in your heart that cause heart rhythm problems. It is a form of cardiac ablation. Your doctor has advised you to have this procedure as your atrial fibrillation (AF) has proved dificult to treat with medication.

Oct 22, 2024 · Pulmonary vein isolation (PVI) remains the cornerstone of atrial fibrillation (AF) ablation strategies. 1 In comparison with alternatives, PVI has been shown to have higher success rates, lower complication rates, and better long-term outcomes in terms of freedom from AF (FFAF) recurrence and improvement in quality of life. 2,3 Still, in a ...

Aug 29, 2023 · Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. 1, 2 However, recurrence of AF and atrial tachycardia (AT) after PVI is frequently observed, especially in patients with persistent AF.

Aug 22, 2024 · Pulmonary vein isolation (PVI) is a standard strategy for atrial fibrillation (AF) using radiofrequency (RF) catheters. 1,2 Ensuring the formation of durable transmural lesions while preventing pulmonary vein (PV) reconnections is crucial for achieving successful ablation for AF.

Apr 10, 2024 · Pulsed-field ablation (PFA) has shown promising data in terms of safety and procedural efficiency for pulmonary vein isolation (PVI), with similar long-term outcomes compared to radiofrequency ablation (RFA) and cryoballoon ablation (CBA) in patients with paroxysmal atrial fibrillation (AF).

Mar 7, 2025 · Pulmonary vein isolation (PVI) is the core strategy of catheter ablation for the treatment of paroxysmal atrial fibrillation (PAF), which has been proven effective in clinical practice and can improve the quality of life in patients with PAF [1]. Quantitative ablation guided by lesion size index (LSI), an integrated radiofrequency (RF) parameter that combines time, …
