BACKGROUND: Effective treatment of paroxysmal atrial fibrillation (AF) is essential for reducing the risk of stroke and heart failure. Cryoballoon (CB) ablation has been developed as an alternative to the use of radiofrequency (RF) energy for electrical isolation of the pulmonary veins. Herein, we provide long-term data regarding the efficacy of CB ablation in comparison to RF. METHODS: FreezeAF was a randomised non-inferiority study comparing CB ablation with RF ablation for the treatment of patients with drug-refractory paroxysmal AF...

BACKGROUND: Verification of pulmonary vein isolation (PVI) can be challenging due to the coexistence of pulmonary vein potentials (PVP) and far field potentials. This study aimed to prospectively validate a novel algorithm for automated verification of PVI in radiofrequency-guided (RF) and cryoballoon-guided (CB) ablation strategies. METHODS: A dataset of 620 (RF: 516 EGMs and CB: 104 EGMs) bipolar electrograms (EGM), recorded by circular mapping catheter (CMC) placed at the left atrium-pulmonary vein (PV) junction, were prospectively analyzed by a two-step algorithm...

INTRODUCTION: The findings of many new cardiology clinical trials over the last year have been published or presented at major international meetings. This paper aims to describe and place in context a summary of the key clinical trials in cardiology presented between January and December 2016. METHODS: The authors reviewed clinical trials presented at major cardiology conferences during 2016 including the American College of Cardiology (ACC), European Association for Percutaneous Cardiovascular Interventions (EuroPCR), European Society of Cardiology (ESC), European Association for the Study of Diabetes (EASD), Transcatheter Cardiovascular Therapeutics (TCT), and the American Heart Association (AHA)...

Data evaluating the impact of the periprocedural administration of novel oral anticoagulants (NOACs) on complications in the setting of pulmonary vein (PV) isolation using cryoballoon (CB) is limited. In the present study, our aim was to analyze procedural characteristics and incidence of complications in those patients who underwent CB ablation for atrial fibrillation and the impact of NOACs on adverse events compared with vitamin K antagonists (VKAs). Consecutive patients with drug resistant atrial fibrillation who underwent PV isolation by CB as index procedure were retrospectively included in our analysis...

BACKGROUND: Achieve catheters are cryoballoon guidewires that enable pulmonary vein (PV) potential mapping. The single catheter approach in conjunction with the Achieve catheter is currently standard practice in second-generation cryoballoon ablation, yet circumferential mapping catheters are the gold standard for evaluating PV isolation (PVI). The study sought to validate the ostial PVI verified by an Achieve catheter alone. METHODS: One-hundred fifty-one paroxysmal atrial fibrillation patients undergoing PVI using exclusively 28-mm second-generation cryoballoons were enrolled...

Introduction: We aimed to study the procedural characteristics, efficacy and safety of cryoballoon ablation (CBA) versus radiofrequency ablation (RFA) for catheter ablation of paroxysmal atrial fibrillation (AF). Methods: A systematic literature search was performed using PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials to clinical trials comparing CBA and RFA for AF. Outcomes were evaluated for efficacy, procedure characteristics and safety. For each study, odd ratio (OR) and 95% confidence intervals (CIs) were calculated for endpoints for both approaches...

Balloon breach during cryoablation: To date, this is the first published report of a double-wall breach while using the cryoballoon ablation catheter during the treatment of a patient with atrial fibrillation; however, there have been previous balloon breaches in both the second and third-generation cryoballoon ablation catheter usage. In this report, we describe the case of a double-wall balloon breach and the intraoperative care that was necessary to stabilize the patient. Additionally, we review other known cases of double-wall balloon breaches, and we examine the safety systems of the cryoballoon catheter that mitigate some of the potential patient complications...

BACKGROUND: Cryoballoon ablation of atrial fibrillation (AF) involves successful electrical pulmonary vein isolation (PVI). Pulmonary vein (PV) ostial occlusion with cryoballoon is classically assessed using PV angiography. A pressure-guided technique to assess ostial occlusion has been evaluated in small cohorts with mixed results. We evaluated the efficacy of this pressure-guided PVI technique and its impact on reducing contrast and fluoroscopy time as compared to the traditional approach...

Antonis S Manolis
Over the recent years, the advent of single-shot techniques, such as circular catheter and cryoballoon ablation, has ushered in a new era in the catheter ablation approach and rhythm control strategies of patients with atrial fibrillation (AF). These techniques make it easier to navigate the heart and have the potential to decrease the threshold for, expand the access to, and increase patient and physician acceptance of rhythm-control therapies, that may lead to reduction of the AF disease burden and its socioeconomic impact...

PURPOSE OF REVIEW: Providing an overview on types of cryotherapy for esophageal application and their role in the management of Barrett's esophagus. RECENT FINDINGS: Recent studies have involved multiple types of cryotherapy including cryospray techniques that use either liquid nitrogen or carbon dioxide as the cryogenic fluid, and the CryoBalloon focal ablation device that uses nitrous oxide. Overall, studies report cryotherapy to be safe and effective in eradicating Barrett's epithelium...

Atrial fibrillation (AF) is the most common form of cardiac arrhythmia. The aim of therapy in symptomatic patients is the establishment of a stable sinus rhythm (SR). Catheter ablation with isolation of the pulmonary veins is the essential component of all forms of ablation therapy and provides the most effective treatment option. The most frequently used technologies for pulmonary vein isolation (PVI) are radiofrequency current (RFC)-based and cryoballoon (CB)-guided ablation. Irrespective of the simplification of PVI, CB ablation is characterized by a short learning curve and short procedural times and demonstrated non-inferiority with respect to safety and efficacy when directly compared to RFC ablation for the treatment of patients with paroxysmal AF; however, the clinical outcome in patients with persistent AF is often insufficient when performing pulmonary vein isolation (PVI) alone for stabilization of SR...

BACKGROUND: Diaphragmatic compound motor action potential (CMAP) amplitude monitoring is a standard technique to anticipate phrenic nerve injury during cryoballoon ablation. OBJECTIVE: The purpose of this study was to evaluate the feasibility of a novel superior vena cava isolation (SVCI) technique using simultaneous pacing and ablation through the tip of a single mapping/ablation catheter. METHODS: Fifty-four patients with atrial fibrillation were included...

BACKGROUND: Few data are available on gastric hypomotility (GH) after cryoballoon pulmonary vein isolation. Also, the use of esophageal temperature monitoring for the prevention of endoscopically detected esophageal lesions (EDELs) is not well established. OBJECTIVE: The purpose of this study was to investigate GH and the impact of an esophageal probe on EDELs during second-generation cryoballoon ablation. METHODS: One hundred four patients with paroxysmal atrial fibrillation undergoing second-generation cryoballoon ablation under conscious sedation followed by esophagogastroscopy were prospectively included...
