INTRODUCTION: Cryoballoon ablation (CB) has proven effective for treating patients with paroxysmal atrial fibrillation (PAF). We analyzed our seven year follow-up of patients, treated for PAF with first (CB1) and second generation (CB2), with demonstration of LA-PV disconnection with bidirectional block (BB) after adenosine (AD). METHODS: Since November 2008 to May 2015, 128 patients, 97 male (58±7 years), without heart disease, highly symptomatic, refractory to antiarrhythmic drugs (AAD) were treated, and follow-up (1411 ±727 days)...

Introduction Cryoballoon ablation (CB) has proven effective to treatment of patients (pts) with atrial fibrillation (AF). However, the isolated efficacy of CB to treat pts with long-standing persistent atrial fibrillation (LSPAF) is less know. We analyzed the acute results and the long-term follow-up of our pts suffering LSPAF and initially treated with CB. Methods A cohort of 44 pts, 37 male (84%) mean age (60±10 year) suffering LSPAF were treated with first (CB1): 15pts, and second (CB2): 29 pts, generation CB...

BACKGROUND: Catheter ablation (CA) is recommended for patients with drug refractory symptomatic atrial fibrillation (AF). "One Shot" catheters have been introduced to simplify CA and cryoballoon-ablation (CBA) is spreading rapidly. Few real-world data are available on standard clinical practice, mainly from single center experience. We aimed to evaluate clinical settings, demographics and acute procedural outcomes in a large cohort of patients treated with CBA. METHODS: 903 patients (73% male, mean age 59±11) underwent pulmonary veins CBA...

Cryoballoon ablation is a widely diffuse technology to perform paroxysmal atrial fibrillation ablation. The new generation cryoballoon catheters have been redesigned in order to improve the cooling capability. During cryoballoon ablation, it is not unusual to observe the formation of a contrast dye ice cap on top of the balloon itself. The automated balloon deflation before dissolution of the ice cap may increase the risk of embolization of large ice-mixed-contrast crystals in the systemic circulation. In the case hereby reported, we describe an uneventful embolization of this contrast dye ice cap in the systemic circulation...

INTRODUCTION: Comparative data of early recurrence rates of atrial fibrillation (ERAF) following second-generation cryoballoon (CB-G2) and radiofrequency current (RFC) ablation for pulmonary vein isolation (PVI) in paroxysmal AF (PAF) are rare. We randomized PAF patients into either PVI with CB-G2 (group 1) or PVI with a combined RFC-approach applying contact force (CF) with the endpoint of unexcitability (group 2) to investigate ERAF. METHODS: In group 1 (n = 30), CB-G2-PVI was performed...

AIMS: Although the generation of linear lesions by ablation improves success rates in patients with persistent atrial fibrillation (AF), the procedure has been considered unsuitable for cryoablation balloon catheter technologies. We developed a technique for linear ablations, using second-generation cryoballoon technology. METHODS AND RESULTS: This was a single-arm, prospective study in 76 patients with persistent AF treated consecutively at our centre. Cryoablation was performed using a 28 mm second-generation cryoballoon...

BACKGROUND: Although several prognostic factors of atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI) have been investigated, the accurate prediction of AF recurrence remains difficult. We propose an electrocardiogram (ECG) index, the P-wave force (PWF), which is the product of the amplitude of the negative terminal phase of the P wave in the V1 electrode and the filtered P-wave duration, obtained by a signal-averaged P-wave analysis. This study was conducted to evaluate the impact of the PWF on the recurrence of AF after PVI...

AIMS: There is no objective, early indicator of occlusion quality, and efficacy of cryoballoon pulmonary vein isolation. As previous experience suggests that the initial cooling rate correlates with these parameters, we investigated the slope of the initial temperature drop as an objective measure. METHODS AND RESULTS: A systematic evaluation of 523 cryoapplications in 105 patients using a serial ROC-AUC analysis was performed. We found the slope of a linear regression of the temperature-time function to be a good predictor (PPV 0...

AIMS: Pulmonary vein (PV) isolation (PVI) utilizing a cryoballoon (CB) has become one of the standard therapeutic options for atrial fibrillation (AF). However, it connotes a potential risk of cerebral ischaemic events (CIEs). This study aimed to clarify the prevalence of CIEs after PVI using second-generation CBs assessed by magnetic resonance imaging (MRI) of the brain. METHODS: This prospective observational study consisted of 160 patients that underwent PVI with second-generation CBs for drug-refractory AF...

PURPOSE: Currently, radiofrequency (RF) and cryoballoon are the most commonly used ablation technologies for atrial fibrillation (AF). We performed a meta-analysis to assess the efficacy and safety of the second-generation cryoballoons (CB-2) compared with RF for paroxysmal atrial fibrillation (PAF) ablation. METHODS: The PubMed, Cochrane Library, and Embase databases were searched and qualified studies were identified. The primary clinical outcome was the recurrence rate of atrial tachyarrhythmia (AT), and the secondary clinical outcomes were procedure time, fluoroscopy time, and the complications that followed...

PURPOSE: Pulmonary vein isolation using cryoballoon ablation is an established approach to treating atrial fibrillation. The procedure involves insertion of a 15-Fr sheath into the left atrium across the interatrial septum. This creates an iatrogenic atrial septal defect, which may have important long-term clinical relevance, especially in younger patients. We sought to determine the long-term incidence of these defects and determine the direction of shunt using contrast transesophageal echocardiography...

BACKGROUND: Pulmonary vein isolation is an established therapy for symptomatic atrial fibrillation. Despite the fact that incidence and prevalence of atrial fibrillation increases with age, patients over 75 years of age have been excluded in all major atrial fibrillation ablation trials. Pulmonary vein isolation with the cryoballoon has been shown to be equally effective compared to irrigated radiofrequency catheter ablation, but patients over 75 years have also been excluded. The 2nd generation cryoballoon has shown superior efficacy compared to the 1st generation cryoballoon...

Background: Atrial fibrillation (AF) represents a turning point in hypertrophic cardiomyopathy (HCM). Pulmonary Vein Isolation (PVI) with Radiofrequency Catheter Ablation (RFCA) is accepted to be successful in restoring sinus rhythm (SR) in HCM patients. The efficacy of cryoballoon (CB) therapy in HCM patients has not been studied so far. Methods: 166 patients with AF underwent PVI with CB technology in our single center between 1/2012 and 12/2015. To evaluate the efficacy of the CB therapy in HCM patients, we compared their clinical outcome with those in "Non-HCM" AF patients in a 3 and 6 months follow-up...
