Left Atrial Function Post Radiofrequency and Cryoballoon Ablation Assessed by Volume-Pressure Loops

Frontiers in Cardiovascular Medicine, 2022
BackgroundLeft atrial (LA) function is linked to atrial fibrillation (AF) pathogenesis. AF catheter ablation decreases disease burden with potentially favorable effects on cardiac function.

Gastric Hypomotility Unmasking a Phytobezoar After Cryoballoon Pulmonary Vein Isolation

Journal of Arrhythmia, Volume 42, Issue 6, December 2026.
After cryoballoon pulmonary vein isolation, acute gastric hypomotility progressed to phytobezoar formation. The admission CT had already shown a mottled intragastric mass with entrapped gas, initially interpreted as retained food; when post‐ablation symptoms persist, clinicians should re‐examine the original imaging before escalating therapy.

Electrophysiology lab efficiency using cryoballoon for pulmonary vein isolation in central and eastern Europe: A sub-analysis of the cryo global registry study

Cardiology Journal
BACKGROUND: Cryoballoon ablation for treatment of atrial fibrillation (AF) reduces procedure times, but limited data is available about its impact on electrophysiology (EP) lab efficiency in Central and Eastern Europe (CEE).

Comparison of Effects of Pulsed Field Ablation and Cryoablation on Left Atrial Stiffness Using Invasively Derived Pressure–Volume Relationship

Journal of Arrhythmia, Volume 42, Issue 6, December 2026.
No differences were noted between pulsed field ablation and cryoballoon ablation regarding mechanical properties of the left atrium, assessed by invasively acquired P–V relationship, following first‐time ablation for atrial fibrillation. ABSTRACT Background Acute effects of pulsed field ablation (PFA) on passive atrial mechanical properties have not ...

Radiofrequency or cryoablation or medical therapy for paroxysmal atrial fibrillation: An indirect comparison of effectiveness

Journal of Arrhythmia
Background Paroxysmal atrial fibrillation (PAF) is commonly treated with pharmacological therapies, but these may be insufficient for symptom control. Radiofrequency and cryoballoon ablation have emerged as alternative strategies.

Cryoballoon Versus Radiofrequency Ablation for Persistent Atrial Fibrillation: Meta‐Analysis of Randomized Trials

Pacing and Clinical Electrophysiology, Volume 49, Issue 11, Page 1692-1705, November 2026.
ABSTRACT Introduction Pulmonary vein isolation (PVI) alone achieves modest arrhythmia freedom in persistent atrial fibrillation (PeAF). Cryoballoon ablation (CBA) offers a single‐shot alternative to radiofrequency ablation (RFA) that streamlines procedural workflow.

Epicardial Connection as a Resource of Atrial Fibrillation Recurrence After Pulsed Field Ablation: A Case Report

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT This case highlights an uncommon but clinically important mechanism of atrial fibrillation recurrence after Pulsed field ablation. It emphasizes the importance of ablation along the ridge during the first session and also the need for careful evaluation of epicardial conduction, particularly in patients with a left common pulmonary vein.

Moving Air in the Esophagus During Cryoballoon Ablation [PDF]

Journal of Innovations in Cardiac Rhythm Management, 2019
A 56-year-old male patient underwent cryoballoon ablation for symptomatic paroxysmal atrial fibrillation. Massive air movement reminiscent of an air esophagram was detected during cryoballoon application in the right superior pulmonary vein. In this case report, we sought to consider all possible explanations of this finding.

Association Between the Change in Interleukin‐6 Levels and Early Recurrence of Atrial Fibrillation: A Comparison of Pulsed Field Ablation and Radiofrequency Ablation

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Despite causing greater myocardial injury and hemolysis, pulsed field ablation induces significantly less systemic inflammation than radiofrequency ablation. This reduced inflammatory response is independently associated with a lower incidence of early atrial fibrillation recurrence.

Cryoballoon ablation of focal atrial tachycardia originating from right atrial appendage: Case report and review of the literature

Indian Pacing and Electrophysiology Journal, 2019
The right atrial appendage (RAA) is a rare site of focal atrial tachycardia (AT). Sometimes, catheter ablation cannot successfully be accomplished at this location due to the difficulty in reaching the exact ablation site as well as the associated ...
