Pulmonary vein atrial tachycardia (PVAT) is a rare arrhythmia that accounts for 3% of all atrial tachycardia types. On electrocardiogram, fast PVATs may be misinterpreted as atrial fibrillation at first glance. We present a case of PVAT refractory to pharmacological intervention in a 31-year-old, requiring ablation to terminate the arrhythmia.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardial condition that mostly affects the right ventricle (RV). Atrial involvement is poorly understood and the evidence for atrial involvement remains limited. In this case report, we describe an 18-year-old woman who had ARVC with the atrial tachyarrhythmia and initially presented with palpitations.

Purpose Of Review: This review aims to explore how a diagnosis of LMNA-related cardiomyopathy (LMNA-CM) informs clinical management, focusing on the prevention and management of its complications, through practical clinical strategies.
Recent Findings: Longitudinal studies have enhanced our understanding of the natural history of LMNA-CM including its arrhythmic and non-arrhythmic complications. A LMNA specific ventricular arrhythmia risk prediction strategy has been integrated into clinical practice guidelines.
Predictors of Arrhythmia Recurrence After Cryoballoon Ablation for Persistent Atrial Fibrillation: A Sub-Analysis of the Cryo Global Registry.

Introduction: Freedom from recurrences of atrial tachyarrhythmia (ATA) is suboptimal after pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (PsAF). This sub-analysis from the Cryo Global Registry sought to investigate predictors of ablation success after PVI using cryoballoon ablation (CBA) for PsAF.
Methods And Results: ATA recurrence was defined as ≥ 30 s recurrence of atrial fibrillation, atrial flutter or atrial tachycardia after a 90-day blanking period and through 12-months.
Sodium-glucose cotransporter 2 inhibitors and outcomes in transthyretin amyloid cardiomyopathy: Systematic review and meta-analysis.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) commonly leads to heart failure but has traditionally been an exclusion criterion in randomized clinical trials (RCTs) of sodium-glucose cotransporter 2 inhibitors (SGLT2i); therefore, the effects of these drugs in this population remain undocumented. In light of recent studies, this meta-analysis aimed to investigate the effect of SGLT2i on the prognosis of patients with ATTR-CM.
Methods: A comprehensive search of Medline, Scopus, and the Cochrane Library was conducted up to November 17, 2024.
