Efficacy and safety of once-daily carvedilol in atrial fibrillation patients: a randomized, double-blind, placebo-controlled trial
Heart rate (HR) control is a mainstay of atrial fibrillation (AF) management. Guidelines recommend first-line β-blockers for HR control in paroxysmal, persistent, or permanent AF.1 Carvedilol, a non-selective β-blocker, has a documented HR-lowering effect; in a dose-escalation study of Japanese patients with chronic AF (AF Carvedilol study), each dose of carvedilol (5, 10 or 20 mg, once daily) significant ly reduced HR from baseline (HR ≥80 bpm) during 6 weeks of treatment.2 Although off-label carvedilol indications include AF,3 there are currently no phase 3 clinical trial data to support carvedilol use for HR control...

Incidence of Newly Recognized Atrial Fibrillation in Patients with Obstructive Hypertrophic Cardiomyopathy Treated with Mavacamten
Mavacamten is a cardiac myosin inhibitor that has been shown to reduce left ventricular outflow tract obstruction in obstructive hypertrophic cardiomyopathy (oHCM).1 In late-stage clinical trials, atrial fibrillation (AF) represented an adverse event in 2-4 % of the patients randomized to mavacamten.1,2 However, the effect of mavacamten on the frequency and management of new/recurrent AF episodes in oHCM receiving mavacamten following its Food and Drug Administration (FDA) approval remains only partially explored.

Atrial Fibrillation Ablation in Patients with Pulmonary Hypertension: Multicenter Experience
Pulmonary hypertension (PH) is a progressive condition characterized by pulmonary vascular remodeling and elevated pulmonary arterial pressure. Atrial arrhythmias are common in PH and may contribute to right ventricular failure and death1,2. We retrospectively identified patients with pre-capillary PH who underwent catheter ablation for AF at four high-volume ablation centers. Included patients had an established clinical diagnosis of PH, with suspected pre-capillary etiology, and at least one right heart catheterization showing mean pulmonary artery pressure>20 mm Hg and pulmonary capillary wedge pressure ≤15 mm Hg.

Acute Kidney Injury after Catheter Ablation of Atrial Fibrillation: Comparison between Different Energy Sources
Pulsed field ablation (PFA) is an innovative technology recently adopted for treating atrial fibrillation (AF). Preclinical and clinical studies have reported a reassuring safety profile because of its tissue-specific effect, sparing adjacent tissues.1 However, two cases of acute kidney injury (AKI) secondary to hemolysis after PFA have recently been reported after an uncommonly high number of applications.2,3 Similarly, a subsequent pilot study reported the occurrence of AKI in 4/28 patients after PFA for AF.

Left bundle branch block-induced cardiomyopathy: a distinctive form of cardiomyopathy that might require a dedicated form of treatment.
The His-Purkinje system is the ventricular component of the cardiac conduction system that orchestrates the electrical impulse propagation which underlies every contraction of the heart. It originates from the AV-node and runs down to the interventricular septum and subdivides into the left and right bundle branches. These major branches divide further and spread diffusely along the sub endocardium. [1],[2] Damage in one of those branches may result in impaired electrical conduction. (Source: Heart Rhythm)

Relationship between wait-times and post-atrial fibrillation ablation outcomes: a population based study
Rhythm control is a cornerstone of atrial fibrillation (AF) management. Shorter time between diagnosis of AF and receipt of catheter ablation is associated with greater rates of therapy success. Prior work considered diagnosis-to-ablation time as a binary or categorical variable and did not consider the unique risk profile of patients once a referral for ablation is made.
