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...

BACKGROUND: Early studies demonstrated relatively low success rates for pulmonary vein isolation (PVI) alone in patients with persistent atrial fibrillation (PeAF). However, the advent of new technologies and the observation that additional substrate ablation does not improve outcomes have created a new focus on PVI alone for treatment of PeAF. OBJECTIVE: The purpose of this study was to systematically review the recent medical literature to determine current medium-term outcomes when a PVI-only approach is used for PeAF...

INTRODUCTION: Left atrial pulmonary vein isolation (PVI) is an accepted treatment option for patients with symptomatic atrial fibrillation (AF). This procedure can be complicated by stroke or silent cerebral embolism. Online measurement of microembolic signals (MESs) by transcranial Doppler (TCD) may be useful for characterizing thromboembolic burden during PVI. In this prospective multicenter trial, we investigated the burden, characteristics, and composition of MES during left atrial catheter ablation using a variety of catheter technologies...

BACKGROUND: Pulmonary vein isolation (PVI) is a cornerstone of catheter ablation in patients with paroxysmal atrial fibrillation (PAF), and balloon-based ablation has been recently performed worldwide. Ablation using the second-generation cryoballoon (CB2) (Arctic Front Advance(TM), Medtronic, MN, USA) is useful for PVI; however, there is some debate concerning the optimal freezing time and number of cycles after PVI is achieved. METHODS: The AD-Balloon study was designed as a prospective, multicenter, randomized clinical trial to evaluate the optimal strategy (freezing cycles) of CB2 ablation (UMIN Clinical Trials Registry UMIN000020130)...

Aims: In this double centre, retrospective study, we aimed to analyse the 1-year efficacy and safety of cryoballoon ablation (CB-A) in patients older than 75 years compared with those younger than 75-years old. Methods and results: Fifty-three consecutive patients aged 75 years or older with drug-resistant paroxysmal AF (PAF) who underwent pulmonary vein isolation (PVI) by the means of second generation CB-A, were compared with 106 patients aged <75 years. The mean age in the study group (>75 years) was 78...

Aims: Procedure times and left atrial dwell times of cryoballoon (CB)-based ablation strategies for atrial fibrillation (AF) are shorter as compared to radiofrequency ablation, yet fluoroscopy times are longer and result in a higher radiation exposure. The objective of this study is to evaluate a modified fluoroscopy protocol aiming at reduction of radiation exposure in CB ablation. Methods: A total of 120 patients with symptomatic AF underwent pulmonary vein isolation (PVI) using the second generation CB and an ablation strategy considering the individual time-to-isolation...

PURPOSE: Pressure waveform analysis has the potential for facilitated assessment of pulmonary vein occlusion during cryoballoon ablation for atrial fibrillation. Data on clinical outcomes using this method are lacking. We sought to validate through clinical outcomes the use of pressure waveform analysis as the primary method of determining pulmonary vein occlusion during cryoballoon ablation. METHODS: A study was performed of 122 consecutive patients with atrial fibrillation (85% paroxysmal) undergoing cryoballoon ablation from May 2014 through July 2015 at a single institution using pressure waveform analysis as the primary method of assessing pulmonary vein occlusion...

BACKGROUND: Pulmonary vein isolation (PVI) using the 2nd-generation cryoballoon (CB2) for the treatment of atrial fibrillation (AF) has demonstrated encouraging acute and mid-term results. However, follow-up data on outcomes beyond 1 year are sparse. We investigated the 3-year outcome after PVI using the CB2.Methods and Results:100 patients with paroxysmal (PAF, 70/100 [70%] patients) or persistent AF (pAF, 30/100 [30%] patients) underwent CB2-based PVI in 2 experienced centers in Germany...

Aims: In this study, we sought to evaluate the safety and efficacy of cryoballoon (CB) based empirical left atrial appendage (LAA) isolation as an adjunct to pulmonary vein isolation (PVI) compared to the PVI-only strategy in patients with persistent AF. Objectives: Clinical outcomes of catheter ablation were less beneficial for persistent atrial fibrillation (AF) than paroxysmal AF. Methods and results: A total of 100 consecutive patients with persistent AF underwent both PVI and additional LAA isolation using CB (Group II)...

Aims: The therapeutical management of atrial fibrillation (AF) in the setting of Brugada syndrome (BS) might be challenging as many antiarrhythmic drugs (AADs) with sodium channel blocking properties might lead to to the development of ventricular arrhythmias. This study sought to evaluate the clinical outcome in a consecutive series of patients with BS having undergone pulmonary vein (PV) isolation by means of radiofrequency (RF) or cryoballoon (CB) ablation and the efficacy of catheter ablation for preventing inappropriate interventions delivered by implantable cardioverter defibrillators (ICD) on a 3-year follow up...

PURPOSE: Pulmonary vein isolation is now widely accepted for the treatment of symptomatic atrial fibrillation refractory to antiarrhythmic drugs. However, multiple procedures are often required to significantly reduce atrial fibrillation (AF) recurrence. In the present study, we analyzed the acute results and the midterm clinical outcome of a second-generation cryoballoon ablation (CB-A) performed during repeat procedures for recurrence of AF after an initial procedure performed with conventional radiofrequency (RF)...
