Aims: The efficacy of the second-generation cryoballoon (CB) ablation in patients with atrial fibrillation (AF) has been demonstrated previously. Data on the efficacy of CB ablation in elderly patients is missing. The aim of this study was to evaluate the long-term success rate of pulmonary vein isolation (PVI) in patients ≥75 years vs. <75 years using the second-generation 28mm CB. Methods and results: Eighty patients [n = 40 ≥75 years (Group 1); n = 40 <75 years (Group 2)] with paroxysmal [n = 37 (46%) or persistent (n = 43 (54%)] AF were included...

OBJECTIVE: Pulmonary vein isolation (PVI) ablation has emerged as the gold standard of ablative strategies to treat medically refractory paroxysmal and persistent atrial fibrillation (AF). Regardless of the superiority of catheter ablation based on PVI over antiarrhythmic drug therapy, recurrence rates of AF remain higher than desired. PVI via cryoablation has rapidly become a mainstream treatment for AF, due to its effectiveness and fast learning curve. Our objective was to assess the safety and efficacy of cryoablation in a single referral center...

Atrial fibrillation is associated with increased morbidity and mortality in patients undergoing mitral valve surgery. There is a growing consensus that patients with preexisting atrial fibrillation should undergo surgical ablation at the time of mitral valve surgery. Novel surgical ablation techniques, including cryoablation, have been developed to facilitate concurrent minimally invasive procedures. This video tutorial describes a combined cryo-maze procedure and mitral valve repair through an upper ministernotomy in a patient with long-standing persistent atrial fibrillation and severe mitral regurgitation...

BACKGROUND: Atrial fibrillation (AF) usually originates from pulmonary veins (PVs) but can also be caused by pulmonary veins outside, such as the coronary sinus (CS), the superior vena cava (SVC), and the ligament of Marshall. CASE PRESENTATION: A 69-year-old male with a history of palpitations for 10 years was referred to our institute because of its recurrence for half a day. A dynamic electrocardiogram revealed sinus rhythm (SR) and paroxysmal AF. Echocardiography demonstrated normal cardiac structure, and physical examination results were unremarkable...

AIMS: Several studies have investigated the influence of pulmonary vein(PV) anatomy on outcomes of atrial fibrillation (AF) ablation. We aimed to evaluate the relationship between PV orientation and AF-free survival following cryoablation. METHODS: 160 patients scheduled for cryoablation between September 2012-March 2014 were included. Patients underwent a pre-procedural cardiac CT scan with retrospective ECG gating. PV orientation was assessed according to the position of the PV orifice relative to the sagittal plane with reference to coronal and horizontal planes...

REVIEW
Jorge Romero, Andrea Natale, Luigi Di Biase
The role of pulmonary vein isolation in patients with non-paroxysmal atrial fibrillation (AF) is only modest. Several studies have demonstrated the role of the left atrial appendage (LAA) in initiating and maintaining of this arrhythmia. We review in this article the incremental benefit in free-arrhythmia recurrence of LAA electrical isolation in patients undergoing procedures for persistent AF or long standing persistent AF either using radiofrequency ablation, cryoablation or Lariat device implantation. Likewise, acute complications, anticoagulation and the risk of ischemic stroke after LAA electrical isolation (LAAEI) are analyzed...

REVIEW
Serge Boveda
Pulmonary vein isolation is the cornerstone of atrial fibrillation ablation and is effective for preventing arrhythmias recurrences, especially in patients with paroxysmal atrial fibrillation. During the last years, cryoballoon ablation has emerged as an unquestionable alternative approach to radiofrequency ablation. Many non-randomized and randomized trials have proven undoubtedly that cryoballoon ablation displays similar efficacy and overall safety profile, when compared to radiofrequency ablation for the treatment of patients with drug-refractory paroxysmal atrial fibrillation...

BACKGROUND: Cryoballoon ablation for atrial fibrillation (cryoAF) is relatively simple, cost-effective and easy procedure. However, general anesthesia during this procedure may have negative impact on patients' mortality and morbidity, as well as procedure costs. We sought to assess the feasibility and safety of conscious sedation during cryoAF. METHODS: Patients with paroxysmal or persistent, drug-refractory AF who underwent a first procedure of cryoAF were included in our single-center, retrospective study...

AIM: To evaluate the long-term outcome of catheter ablation of atrial fibrillation (AF) facilitated by preprocedural three-dimensional (3-D) transesophageal echocardiography. METHODS: In 50 patients, 3D transesophageal echocardiography (3D TEE) was performed immediately prior to an ablation procedure (paroxysmal AF: 30 patients, persistent AF: 20 patients). The images were available throughout the ablation procedure. Two different ablation strategies were used. In most of the patients with paroxysmal AF, the cryoablation technique was used (Arctic Front Balloon, CryoCath Technologies/Medtronic; group A2)...

BACKGROUND: There are no recommendations on the optimal dosing for cryoablation of atrial fibrillation (Cryo-AF). OBJECTIVE: The purpose of this study was to develop and prospectively test a Cryo-AF dosing protocol guided exclusively by time-to-pulmonary vein (PV) isolation (TT-PVI) in patients undergoing a first-time Cryo-AF. METHODS: In this multicenter study, we examined the acute/long-term safety/efficacy of Cryo-AF using the proposed dosing algorithm (Cryo-AFDosing; n = 355) against a conventional, nonstandardized approach (Cryo-AFConventional; n = 400) in a nonrandomized fashion...

BACKGROUND: Catheter ablation has become the first line of therapy in patients with symptomatic, recurrent, drug-refractory atrial fibrillation (AF). Cryoablation has been shown to be a safe and effective technique for pulmonary vein (PV) isolation. However, the arrhythmia recurrence rate is high after cryoablation procedures. Radiofrequency catheter ablation has been shown to be an effective strategy for redo procedures in these patients and to provide a favourable outcome during midterm follow-up...
