Autonomics, More Than Fibrosis, Predict Postoperative Atrial Fibrillation

Histological Determinants of Atrial Dysfunction in Patients With Atrial Fibrillation.

Fibrosis, DNA damage-associated reduction in myocardial nuclear density, and advanced atrial amyloidosis are key determinants of atrial dysfunction and impaired postablation functional recovery in patients with AF.

Association of coronary sinus activation differences with atrial remodeling in atrial fibrillation

Physiological Left Atrial Staging and the Risk of New-Onset Atrial Fibrillation in Hypertrophic Cardiomyopathy.

The proposed LA staging framework offers mechanistic insights into how the LA adapts to progressive diastolic dysfunction in HCM and is associated with a graded risk of NOAF and may help tailor AF surveillance strategies.

Rare Cardiac Genetic Variation Is Associated With Postoperative Atrial Fibrillation.

Rare pathogenic/LP variants in cardiomyopathy genes were associated with risk of POAF and reduced AF-free survival over long-term follow-up across cardiac and noncardiac surgery.

Hemoglobin Levels as a Marker of Arrhythmia Recurrence After Atrial Fibrillation Ablation

ABSTRACT Background Low hemoglobin (Hb) is associated with hemodynamic stress and adverse cardiac remodeling. However, its clinical significance for arrhythmia recurrence after atrial fibrillation (AF) ablation remains unclear. Methods We retrospectively studied 2202 patients undergoing AF ablation between 2014 and 202...

Left atrial remodeling and functional maladaptations in obesity: an invasive pressure-volume analysis

In patients undergoing AF ablation, higher BMI is associated with a predominantly load-related pattern of LA remodeling, characterized by larger LA volume and pressures, greater cyclic wall stress, and a rightward shift of the estimated pressure–volume relationship.
