Atrial Fibrillation and Atrial Fibrosis [PDF]
Journal of Cardiovascular Pharmacology, 2010 Atrial fibrillation (AF) is the most common arrhythmia in humans. It affects 5% of the population older than age 65 years and is projected to rise as the population ages. Experimental data from animal models of AF show that AF is associated with progressive structural and electrical remodeling of the atria.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundCryoballoon pulmonary vein isolation (PVI) has emerged as an alternative to radiofrequency PVI for atrial fibrillation (AF). Data are lacking to define the rates and predictors of complications, particularly phrenic nerve injury (PNI).

Atrial Fibrillation Produced by Atrial Stimulation [PDF]
Circulation, 1968 Twenty-six episodes of atrial fibrillation and flutter-fibrillation, each lasting less than 23 sec, were recorded in three normal subjects during atrial pacing studies. The cause of these atrial arrhythmias was determined to be the result of stimulation within the atrial vulnerable period.

Atrial Cardiomyopathy and Atrial Fibrillation in Cancer [PDF]
Cardiology Research and Practice, 2021 The number of patients with oncologic and cardiologic comorbidities is increasing. A growing number of evidence shows an inextricable link between cancer, atrial fibrillation, and atrial cardiomyopathy. Cancer itself and resultant inflammation, anticancer treatment, and other comorbidities lead to atrial remodeling and fibrosis, which increases the ...

Characterization of pulmonary vein reconnection post Cryoballoon ablation
Indian Pacing and Electrophysiology Journal, 2019 Background: The Arctic Front Cryoballoon System is a technology in which substrate alterations in patients with atrial fibrillation (AF) recurrence have not been well characterized.

Surgical Removal of Migrated Atrial Septal Defect Closure Device: A Case Report
Vascular Specialist International, 2022 Percutaneous closure of atrial septal defects (ASDs) has emerged as an alternative to surgical treatment; however, several early and late complications have been reported. In this report, we present the case of a patient who underwent surgical removal of

Cardiology Research and Practice, 2020 Introduction. Growing evidence suggests that fibrotic changes can be observed in atrial fibrillation (AF) in both atria. Quantification of the scar burden during electroanatomical mapping might have important therapeutic and prognostic consequences ...

Are Three Weeks of Oral Anticoagulation Sufficient for Safe Cardioversion in Atrial Fibrillation?
Medicina, 2021 Background and Objectives: Patients with atrial fibrillation (AF), lasting >48 h, considered for cardioversion, are recommended ≥3 weeks of oral anticoagulation before sinus rhythm restoration because of high risk of development of left atrial thrombosis

Atrial Pressure and Experimental Atrial Fibrillation
Pacing and Clinical Electrophysiology, 1995 SIDERIS, D.A., et al.: Atrial Pressure and Experimental Atrial Fibrillation. A possible profibrillatory effect on the atria of an elevated atrial pressure and the site of atrial stimulation was examined. In 15 anesthetized dogs, right or left atrial or biatrial pacing was applied at a high rate (300–600/min) for 5 seconds at double threshold intensity
