PURPOSE: To describe regional differences in patient characteristics, ablation procedures, and bleeding events in the RE-CIRCUIT study. RE-CIRCUIT was a prospective, multicenter study that captured data from different regions, providing an opportunity to understand the practices followed in various regions. The incidence of major bleeding events (MBEs) was significantly lower with uninterrupted dabigatran versus uninterrupted warfarin. METHODS: Patients were randomized to receive dabigatran 150 mg twice daily or warfarin...

BACKGROUND: Catheter ablation of ventricular arrhythmias (VAs) arising from the left ventricular Summit (LVS) is challenging and requires high-dose fluoroscopy to limit vascular damage of the coronary arteries. Ionizing radiation can increase the incidence of malignancies to both patient and operator. This study describes outcomes of catheter ablation of LVS VAs using intracardiac echo-facilitated 3D electroanatomical mapping (ICE-3D) to avoid fluoroscopy. METHODS: Twenty-six patients (47 ± 17 years old; 52% males; median ejection fraction 55 ± 13%) with premature ventricular contractions or ventricular tachycardia underwent catheter ablation...

PURPOSE: Patients with atrial fibrillation (AF) undergoing cardiac surgery are at substantially increased risk for stroke. Increasing evidence has suggested that surgical left atrial appendage occlusion (S-LAAO) may have the potential to substantially mitigate this stroke risk; however, S-LAAO is performed in a minority of patients with AF undergoing cardiac surgery. We sought to identify factors associated with usage of S-LAAO. METHODS: In a nationally-representative, contemporary cohort (07/2011-06/2012) of older patients undergoing cardiac surgery with preoperative AF (n = 11,404) from the Medicare-linked Society of Thoracic Surgeons Adult Cardiac Surgery Database, we evaluated patient and hospital characteristics associated with S-LAAO use by employing logistic and linear regression models...

INTRODUCTION: Cardiac tamponade is a rare but life-threatening complication during atrial fibrillation (AF) catheter ablation. Contact force (CF)-sensing catheters improve ablation effectiveness. However, the impact of the application of CF-sensing catheters on the occurrence of cardiac tamponade remains unclear. The aim of this study is to evaluate the "real-world" impact of CF-sensing catheters on cardiac tamponade during AF ablation in an experienced medical center. METHODS AND RESULTS: This was a retrospective study of consecutive de novo AF ablation procedures at Beijing Anzhen Hospital between 2013 and 2016...

PURPOSE: The purpose of this study was to evaluate the impact of steerable sheaths on multiple contact force parameters during atrial fibrillation (AF) ablation. Steerable sheaths are commonly used during AF ablation, at an additional cost to standard fixed-curve sheaths. However, there is little data on their incremental value in the era of contact force-guided radiofrequency ablation. METHODS: This multi-center cohort study included consecutive patients undergoing index pulmonary vein (PV) isolation with a force-sensing catheter...

PURPOSE: The role of the autonomic nervous system in the genesis of atrial fibrillation (AF) has been well studied; however, the converse remains poorly understood. Pulmonary veins (PV) contain receptors important in cardiac reflexes. Here, we evaluated reflex responses in patients with paroxysmal AF (PAF) to lower body negative pressure (LBNP). METHODS: Thirty-four PAF patients (including 14 PAF patients post successful PV Isolation; PVI) were compared to 14 age and sex-matched controls...

BACKGROUND: Catheter ablation is considered as the mainstay treatment for patients with symptomatic atrial fibrillation (AF). We aimed to determine the predictors of 30-day readmission after catheter ablation for AF. METHODS: The study cohort consisted of patients who underwent AF catheter ablation (International Classification of Diseases, Ninth Revision 427.31 and procedure code 37.34) in 2014, identified from the National Readmission Database. RESULTS: Our final cohort consisted of 5322 unweighted cases, of which 4736 (89%) constituted the no-readmission group and 586 patients (11%) the readmission group...

BACKGROUND: Pulmonary vein isolation by cryoablation (PVI-C) is a standard therapy for the treatment of atrial fibrillation (AF); however, PVI-C can become a challenging procedure due to the anatomy of the left atrium and pulmonary veins (PVs). Importantly, the utility of imaging before the procedure is still unknown regarding the long-term clinical outcomes following PVI-C. The aim of the analysis is to evaluate the impact of imaging before PVI-C on procedural data and AF recurrence...

BACKGROUND: Although pulmonary vein isolation (PVI) guided by the ablation index (AI) has been well-developed, acute PV reconnections (PVRs) still occur. This study aimed to compare the prognostic performance of the modified AI and its optimal cut-off value for the prediction of acute PVRs to ensure durable PVI. METHODS: Three-dimensional left atrium (LA) voltage maps created before an extensive encircling PVI in 64 patients with atrial fibrillation (AF) (45 men, 62 ± 10 years) were examined for an association between electrogram voltage amplitude recorded from the PV-LA junction and acute post-PVI PVRs (spontaneous PVRs and/or ATP-provoked dormant PV conduction)...
