BACKGROUND: Unrecognized incomplete pulmonary vein isolation (PVI), as opposed to post-PVI pulmonary vein reconnection, may be responsible for clinical recurrences of atrial fibrillation (AF). To date, no data are available on the use of high-resolution mapping (HRM) during cryoballoon (CB) ablation for AF as the index procedure. The aims of this study were: - to assess the value of using a HRM system during CB ablation procedures in terms of ability in acutely detecting incomplete CB lesions; - to compare the 8-pole circular mapping catheter (CMC, Achieve) and the 64-pole mini-basket catheter (Orion) with respect to pulmonary vein (PV) signals detection at baseline and after CB ablation; - to characterize the extension of the lesion produced by CB ablation by means of high-density voltage mapping...

OBJECTIVES: This study provides an update and comparison to a 2010 nationwide survey on cardiac electrophysiology (EP), types and numbers of interventional electrophysiological procedures, and training opportunities in 2015. BACKGROUND: In 2010, German cardiology centers performing interventional EP were identified and contacted to provide a survey on cardiac EP. METHODS: German cardiology centers performing interventional EP in 2015 were identified from quality reports and contacted to repeat the 2010 questionnaire...

AIMS: Cryoablation is an indicated therapy for the treatment of recurrent atrial fibrillation through pulmonary vein isolation; however, the optimal time between first diagnosis of atrial fibrillation and cryoablation is still unknown. We aimed to assess the clinical efficacy and safety of early versus later treatment of patients with paroxysmal atrial fibrillation by cryoablation. METHODS: Five hundred and ten patients underwent atrial fibrillation cryoablation and were prospectively followed for at least 6 months in 43 Italian cardiology centers...

INTRODUCTION: Radiofrequency catheter ablation (RFCA) in atrial fibrillation (AF) patients can cause various complications and atrioesophageal (AE) fistula is one of the most catastrophic complications of RFCA. METHODS AND RESULTS: RFCA registries from 3 cardiovascular centers in Republic of Korea consisted of 5,721 patients undergoing 6,724 procedures. Before undergoing RFCA, patients underwent either computed tomography or magnetic resonance imaging. We evaluated clinical, anatomical, and procedural characteristics of patients who developed AE fistula after RFCA...

The study was aimed at comparing clinical and ultrasonographic results during 3 years of postoperative follow up of patients presenting with lower limb varicose veins (LLVV) and subjected to either surgical or thermal-ablation procedures for removal of pathological reflux along the great saphenous vein (GSV) within the femur The study included a total of 185 patients with clinical class C2-3 LLVV in the system of the GSV. The patients were divided into three groups: Group One consisted of 63 patients subjected to short stripping of the GSV trunk + treatment of the perforant veins (66...

BACKGROUND: The second-generation cryoballoon (CB2) provides effective and durable pulmonary vein isolation (PVI) associated with encouraging and reproducible clinical outcome data. The latest-generation cryoballoon (CB3) incorporates a 40% shorter distal tip, thus allowing for an increased rate of PVI real-time signal recording and facilitating individualized ablation strategies taking the time-to-effect (TTE) into account. However, whether this characteristic translates into favorable clinical success has not been evaluated yet...

BACKGROUND: Bile leakage after hepatectomy still causes relatively serious problems, and some types of bile leakage are intractable. CASE PRESENTATION: We report a case of postoperative isolated bile duct leakage managed successfully by combination therapy of percutaneous transhepatic portal vein embolization (PTPE) and bile duct ablation with ethanol. A 61-year-old man diagnosed with hepatocellular carcinoma underwent partial hepatectomy. On postoperative day 1, bile leakage was detected at the drainage tube...

BACKGROUND: The influence of pulmonary vein (PV) anatomy on cryo kinetics during cryoballoon (CB) ablation is unclear. OBJECTIVE: To investigate the relationship between PV anatomy and cryo kinetics during CB ablation for atrial fibrillation (AF). METHODS: Sixty consecutive patients were enrolled. PV anatomy, including ostial diameters (long, short and corrected), ratio between short and long diameters, ostium shape (round, oval, triangular, and narrow), and drainage pattern (typical, with common trunk, common antrum, ostial branch and supernumerary PV) were evaluated on multi-detector computed tomography (MDCT) images pre-procedure...

METHODS: MEDLINE, Embase and conference abstracts were searched. Eligible studies were randomised controlled trials and case series that included at least 100 patients who underwent GSV EVTA (laser ablation or radiofrequency ablation [RFA]) with duplex ultrasound (DUS) within 30 days...

Aims: Low voltage areas (LVAs) represent advanced remodelling processes in left atrium in patients with atrial fibrillation (AF) and are associated with higher rates of arrhythmia recurrences. However, the prediction of LVA based on clinical parameters is understudied. Recently, we introduced APPLE score to predict rhythm outcomes after catheter ablation. The aim of this study was to analyse (i) LVA prediction using APPLE score and (ii) differences in biomarker profiles according to APPLE score in AF patients...

INTRODUCTION: Data on long-term outcomes of cryoballoon ablation for treatment of atrial fibrillation (AF) are sparse. Here, we report the first 5-year follow-up results and predictors of outcome for pulmonary vein isolation (PVI) using the second-generation cryoballoon (CB-Adv) in patients with symptomatic AF. METHODS AND RESULTS: For this prospective observational study, we enrolled 178 patients with paroxysmal (132/178 [74.2%] patients) or persistent AF who underwent PVI with CB-Adv at our institution during 2012...

BACKGROUND: Vagal reactions of the sinus node during pulmonary vein isolation (PVI) have been reported, however, data on intra-procedural atrioventricular conduction disturbances have been sparse. The present study aimed to investigate the clinical characteristics of atrioventricular conduction block (AVB) during PVI using second-generation cryoballoons. METHODS: A total of 2252 PVs among 568 consecutive atrial fibrillation patients undergoing PVI with 28-mm cryoballoons were analyzed...

BACKGROUND: Mechanisms for persistent atrial fibrillation (AF) are unclear. We hypothesized that putative AF drivers and disorganized zones may interact dynamically over short time scales. We studied this interaction over prolonged durations, focusing on regions where ablation terminates persistent AF using 2 mapping methods. METHODS: We recruited 55 patients with persistent AF in whom ablation terminated AF prior to pulmonary vein isolation from a multicenter registry...

Aims: The goals of this study were to develop a method that combines cryoablation with real-time magnetic resonance imaging (MRI) guidance for pulmonary vein isolation (PVI) and to further quantify the lesion formation by imaging both acute and chronic cryolesions. Methods and results: Investigational MRI-compatible cryoablation devices were created by modifying cryoballoons and cryocatheters. These devices were used in canines (n = 8) and a complete series of lesions (PVI: n = 5, superior vena cava: n = 4, focal: n = 13) were made under real-time MRI guidance...

BACKGROUND: The aim of this study was to categorize the conduction patterns between the right atrium (RA) and the superior vena cava (SVC), and to determine the ideal procedure for SVC isolation using a novel high-resolution mapping system.Methods and Results:RA-SVC conduction was evaluated using the RHYTHMIA system in 113 patients (age 62.8±11.5 years, paroxysmal: 67) with atrial fibrillation (AF) after pulmonary vein (PV) isolation. In 56 patients, a line of conduction block was found to run obliquely just above the sinus node (Block group)...
