AIMS: Atrial fibrillation (AF) ablation is associated with increased circulating markers of inflammation. Innate immune, or inflammation, pathways up-regulate mononuclear cell responses and may increase risk for recurrent arrhythmia. Chemokines and serine protease coagulation pathways both activate innate immune responses. Here, we measured inflammatory markers in peripheral blood samples from patients after cryoballoon and/or radiofrequency pulmonary vein isolation and assessed the capacity for inhibition of chemokine and serine protease pathways to block cell activation...

Patients with atrial fibrillation (AF) are at increased risk of thrombotic events despite oral anticoagulation (OAC). Radiofrequency catheter ablation (RFCA) can restore and maintain sinus rhythm (SR) in patients with AF. To assess whether RFCA improves thrombotic status. 80 patients (71% male, 64 ± 12y) with recently diagnosed AF, on OAC and scheduled to undergo RFCA or DC cardioversion (DCCV) were recruited. Thrombotic status was assessed using the point-of-care global thrombosis test (GTT), before, and 4-6 weeks after DCCV and 3 months after RFCA...

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...

Background -Atrial fibrillation (AF), the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM), is capable of producing symptoms that impact quality of life and is associated with risk for embolic stroke. However, the influence of AF on clinical course and outcome in HCM remains incompletely resolved. Methods -Records were accessed of 1558 consecutive patients followed at the Tufts Medical Center Hypertrophic Cardiomyopathy Institute for 4.8 ± 3.4 years, from 2004 to 2014. Results -Of the 1558 HCM patients, 304 (20%) had episodes of AF, of which 226 (74%) were confined to symptomatic paroxysmal AF (PAF; average 5 ± 5; range 1 to > 20), while 78 (26%) developed permanent AF, preceded by 7 ± 6 PAF episodes...

A 59-year-old man developed massive hemoptysis, 1 month after undergoing cryoablation procedure for atrial fibrillation. He underwent emergent bronchoscopy that revealed massive, active bleeding with clots requiring repeated suctioning, epinephrine, and cold saline injection. The source of bleeding was identified in a follow-up bronchoscopy performed few days later-a 2×3 cm area of ulceration of the left main stem bronchus which was missed in the initial bronchoscopy owing to blood obscuring the field of vision...

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...

BACKGROUND: Low-voltage-guided substrate modification is an emerging strategy in atrial fibrillation (AF) ablation. A major limitation to contemporary bipolar electrogram (EGM) analysis in AF is the resultant lower peak-to-peak voltage (Vpp) from variations in wavefront direction relative to electrode orientation and from fractionation and collision events. We aim to compare bipole Vpp with novel omnipolar peak-to-peak voltages (Vmax) in sinus rhythm (SR) and AF. METHODS AND RESULTS: A high-density fixed multielectrode plaque was placed on the epicardial surface of the left atrium in dogs...

BACKGROUND: Phase mapping has become a broadly used technique to identify atrial reentrant circuits for ablative therapy guidance. This work studies the phase mapping process and how the signal nature and its filtering affect the reentrant pattern characterization in electrogram (EGM), body surface potential mapping, and electrocardiographic imaging signals. METHODS AND RESULTS: EGM, body surface potential mapping, and electrocardiographic imaging phase maps were obtained from 17 simulations of atrial fibrillation, atrial flutter, and focal atrial tachycardia...

BACKGROUND: Experimental studies suggest that angiotensin II-receptor blockers can influence atrial remodeling and may prevent atrial fibrillation (AF). Therefore, we hypothesized that irbesartan may prevent the recurrence of AF following either catheter ablation or electrical cardioversion of AF. METHODS: Study on the Effect of Irbesartan on Atrial Fibrillation Recurrence in Kumamoto (SILK study) is a prospective, multicenter, randomized, and open-label comparative evaluation of the effects of irbesartan and amlodipine on AF recurrence in hypertensive patients with AF who are scheduled to undergo catheter ablation or electrical cardioversion of AF...

Atrial fibrillation (AF) and heart failure (HF) cause numerous hospital admissions. We investigated if AF increases readmissions in patients with HF and whether AF ablation alters readmissions for HF exacerbations. The 2013 Nationwide Readmissions Database was analyzed for all-cause 90-day readmissions, after discharge for HF exacerbation. Kaplan-Meier analysis was used to compare hazard rates for readmissions due to HF exacerbation, after recent ablation versus no ablation. There were 885,270 admissions for HF exacerbation of which 364,447 had coexisting AF...

BACKGROUND: The relation between arrhythmias and stress is known. The aim of our current study was to elucidate whether plasma levels of previously described stress parameters are altered in highly symptomatic patients with atrial fibrillation (AF) per se and in patients undergoing ablation therapy by pulmonary vein isolation (PVI). METHODS: 96 patients with AF undergoing PVI were recruited. Plasma levels of Endothelin-1 (ET-1), MCP-1 and Chromogranin-A (CGA) were measured before and three months after ablation completed with clinical follow-up with respect to AF recurrence...
