Safety and Efficacy Using the Second-Generation Cryoballoon in Patients With Atrial Fibrillation and a Common Ostium of Inferior Pulmonary Veins

Frontiers in Cardiovascular Medicine, 2021
Background: Common ostium of inferior pulmonary veins (COIPV) is a kind of pulmonary vein variation. The safety and efficacy of COIPV isolation using the second-generation cryoballoon (CB) ablation remain unknown.Methods: A total of 10 patients with ...

Biophysics of the Second-Generation Cryoballoon [PDF]

Circulation: Arrhythmia and Electrophysiology, 2015
Current guidelines recommend antral isolation of the pulmonary veins (PV) as the cornerstone of atrial fibrillation ablation.1 Although conventional radiofrequency energy has traditionally been used with a point-by-point approach, cryoablation has emerged as a viable alternative to radiofrequency energy.

Learning Curve of Pentaspline Pulsed‐Field Ablation With Posterior Wall Isolation for Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pentaspline pulsed‐field ablation (PFA) has emerged as a novel modality for pulmonary vein isolation (PVI) and posterior wall isolation (PWI) in persistent atrial fibrillation (AF). However, the learning curve associated with combined PVI + PWI and the contribution of anatomical factors to acute lesion completeness remain ...

Cryoballoon Isolation of the Superior Vena Cava

JACC: Clinical Electrophysiology, 2016
A 54-year-old woman was found to have recurrent tachycardia arising from her superior vena cava (SVC) during pulmonary vein isolation for paroxysmal atrial fibrillation. Application of cryotherapy to the junction between SVC and right atrium gave clear isolation of the SVC, with continued ...

Pulmonary Vein Isolation Alone Versus Adjunctive Ablation for Paroxysmal Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
Clinical Outcomes of Pulmonary Vein Isolation Alone Versus Additional Lesion Sets in Paroxysmal Atrial Fibrillation ABSTRACT Background Pulmonary vein isolation (PVI) is the standard ablation strategy for paroxysmal atrial fibrillation (PAF). Despite guideline recommendations favoring PVI alone in PAF, some operators routinely perform extra pulmonary ...

A multicenter study comparing the outcome of catheter ablation of atrial fibrillation between cryoballoon and radiofrequency ablation in patients with heart failure (CRABL‐HF): Study design

Journal of Arrhythmia, 2020
Background Catheter ablation of atrial fibrillation (AF) is increasingly performed worldwide in patients with heart failure (HF). However, it has been recently emphasized that AF ablation in patients with HF is associated with increased risks of ...

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to
