PURPOSE: Hybrid ablation of atrial fibrillation (AF) is a promising treatment strategy for patients with non-paroxysmal AF, although, data regarding mid-term outcomes are limited. METHODS: Patients with persistent or long-standing persistent AF were enrolled. Initially, a thoracoscopic, right-sided, epicardial ablation was performed, with a goal of creating a box lesion on the posterior wall of the left atrium; a novel versapolar radiofrequency (RF) catheter was used...

PURPOSE: Adjunctive ganglionated plexi (GP) ablation may improve success rates for treatment of atrial fibrillation (AF) when combined with pulmonary vein (PV) isolation. Existing meta-analyses on GP ablation have included observational studies and have not incorporated more recent randomized clinical trial data. Moreover, the impact of AF subtype (paroxysmal vs. persistent) on outcomes of GP ablation has not been well established. METHODS: We performed a meta-analysis of randomized controlled trials (RCTs) comparing GP ablation + pulmonary vein (PV) isolation versus PV isolation alone according to the subtype of AF...

PURPOSE: Left atrial arrhythmia substrate assessment can involve multiple imaging and electrical modalities, but visual analysis of data on 3D surfaces is time-consuming and suffers from limited reproducibility. Unfold maps (e.g., the left ventricular bull's eye plot) allow 2D visualization, facilitate multimodal data representation, and provide a common reference space for inter-subject comparison. The aim of this work is to develop a method for automatic representation of multimodal information on a left atrial standardized unfold map (LA-SUM)...

PURPOSE: Complete pulmonary vein isolation (PVI) is the best documented target for catheter ablation, and different technologies have shown comparable outcomes. The multielectrode phased-RF/duty cycled (PhRF/DC) pulmonary vein ablation catheter (PVAC) and its second generation (PVAC-GOLD) have shown promising clinical results in single and multicenter experiences. Our aim is to assess and compare the safety and efficacy in the real clinical practice among two generations of circular PhRF/DC catheters by performing PVI in patients suffering from recurrent atrial fibrillation (AF)...

PURPOSE: Network meta-analysis (NMA) has advantages including being able to simultaneously compare and rank multiple treatments over traditional meta-analysis. We evaluated by a NMA the optimal antithrombotic strategy during the perioperative period of implantation of cardiovascular implantable electronic devices (CIEDs). METHODS: We performed a network meta-analysis of observational studies (cohort and case-control studies). The eligible studies tested the following antithrombotic therapy during the CIED placement: aspirin, clopidogrel, warfarin, novel oral anticoagulants (NOACs), and heparin bridging...

PURPOSE: Atrial fibrillation (AF) is the most common cardiac dysrhythmia. Appropriate detection of AF and early initiation of oral anticoagulation therapy are critical to reduce the risk of stroke. Patients with implantable cardioverter defibrillators (ICD) are at high risk of developing AF. The purpose of the Dx-AF study is to demonstrate that a novel single-lead VDD-ICD system (Linox smart S DX) will facilitate adequate recognition of sub-clinical AF and ultimately stroke prevention with a comparable safety profile in comparison to VVI-ICD...

PURPOSE: Ultrasound (US)-guided access for venous catheter placement has previously been shown to improve success rates and decrease access-related complications. The purpose of this study was to determine the feasibility of US-guided versus traditional vascular access approaches during implantation of cardiac implantable electronic devices (CIEDs). METHODS: We evaluated outcomes for 816 consecutive patients undergoing new CIED implantation between May 2013 and April 2016 at a single institution with respect to use of US guidance for vascular access (137 with US guidance versus 679 with traditional access techniques)...

PURPOSE: Measuring the anticoagulant effect of heparin during radiofrequency ablation (RFA) in patients taking apixaban and rivaroxaban is challenging, since the activated coagulation time (ACT) does not seem to reflect the true anticoagulant activity of these drugs. We therefore evaluated coagulation properties of apixaban and rivaroxaban during RFA by different coagulation assays to better monitor periprocedural hemostasis. METHODS: The study included 90 patients (61 ± 12 years) with atrial fibrillation who underwent RFA procedures...

PURPOSE: Patients with implantable cardioverter defibrillators (ICDs) have an ongoing risk of sudden incapacitation that may cause traffic accidents. However, there are limited data on the magnitude of this risk after inappropriate ICD therapies. We studied the rate of syncope associated with inappropriate ICD therapies to provide a scientific basis for formulating driving restrictions. METHODS: Inappropriate ICD therapy event data between 1997 and 2014 from 50 Japanese institutions were analyzed retrospectively...

PURPOSE: Recent data suggests that high burden of premature atrial complexes after pulmonary vein isolation predicts recurrences of atrial arrhythmias. The present study sought to assess the role of premature atrial complexes burden in predicting atrial arrhythmias recurrences in patients with atrial fibrillation (AF) who have undergone second-generation cryoballoon ablation (CB-Adv). METHODS: Consecutive patients with drug-resistant paroxysmal atrial fibrillation who underwent pulmonary vein isolation using CB-Adv technology as the index procedure were retrospectively included...

BACKGROUND: Prior studies report permanent pacemaker (PPM)-induced tricuspid regurgitation (TR) in up to one third of cases late post-implantation. We sought to assess the extent of immediate PPM-induced TR. METHODS: Forty patients undergoing PPM implant were prospectively enrolled. Patients with pre-existing moderate or severe TR or an RVSP >50 mmHg were excluded. Pre- and immediate post-implantation transthoracic echocardiography (TTE) analyzed TR grade according to established methods...
