Electrocardiographic and electrophysiological characteristics of idiopathic ventricular arrhythmias with acute successful ablation at the superior portion of the mitral annulus

BMC Cardiovascular Disorders, 2021
Background We sought to identify the electrocardiographic and electrophysiological characteristics of ventricular arrhythmias (VAs), including idiopathic ventricular tachycardia (VT) and premature ventricular contractions (PVCs), with acute successful ...

Natural History of Arrhythmia After Successful Isolation of Pulmonary Veins, Left Atrial Posterior Wall, and Superior Vena Cava in Patients With Paroxysmal Atrial Fibrillation: A Multi‐Center Experience

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background We evaluated long‐term outcome of isolation of pulmonary veins, left atrial posterior wall, and superior vena cava, including time to recurrence and prevalent triggering foci at repeat ablation in patients with paroxysmal atrial fibrillation ...

Do the predictors of right ventricular pacing-induced cardiomyopathy add up?

Indian Heart Journal, 2021
Objective: Knowledge of factors causing pacing-induced cardiomyopathy (PICM) is incomplete. We sought to estimate the incidence and predisposing factors for PICM and evaluate if the risk they portend adds up.

Post-TAVR patients with atrial fibrillation: are NOACs better than VKAs?—A meta-analysis

Frontiers in Cardiovascular Medicine, 2023
ObjectiveThis study aimed to compare the efficacy of novel oral anticoagulants (NOACs) with traditional anticoagulants vitamin K antagonists (VKAs) in patients with atrial fibrillation (AF) post transcatheter aortic valve replacement (TAVR ...

Year in Review in Cardiac Electrophysiology [PDF]

Circulation: Arrhythmia and Electrophysiology, 2020
In the past year, there have been numerous advances in our understanding of arrhythmia mechanisms, diagnosis, and new therapies. We have seen advances in basic cardiac electrophysiology with data suggesting that secretoneurin may be a biomarker for patients at risk of ventricular arrhythmias, and we have learned of the potential role of an NPR-C ...

Bipolar Radiofrequency Catheter Ablation for Ventricular Arrhythmias

Reviews in Cardiovascular Medicine, 2022
A minority of premature ventricular contractions (PVC) and ventricular tachycardias (VT) have an intramural origin, which represents a challenge for conventional radiofrequency ablation.

Adenosine-guided radiofrequency catheter ablation of atrial fibrillation: A meta-analysis of randomized control trials

Journal of Arrhythmia, 2017
Background: The prognostic significance of adenosine-mediated dormant pulmonary vein conduction, and whether such dormant conduction should be eliminated, remains controversial.
