A case of successful radiofrequency catheter ablation for atrial tachycardia originating from the inferior vena cava using high-resolution mapping

Indian Pacing and Electrophysiology Journal, 2022
A 60-year-old man presented with sustained supraventricular tachycardia. Atrial tachycardia (AT), with the earliest atrial activation (EAA) occurring at the ostium of the coronary sinus, was reproducibly induced.Three-dimensional electroanatomical ...

Clinical Utility of Tissue Proximity Indication With a Variable‐Loop Circular Catheter for Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The variable‐loop circular catheter (VLCC, VARIPULSE) is a pulsed‐field ablation (PFA) catheter equipped with a Tissue Proximity Indication (TPI) function, which monitors catheter‐tissue contact. Although TPI‐negative sites have been reported to contribute to gap formation, no studies have evaluated the utility of real‐time function.

Non-fluoroscopic catheter ablation: A randomized trial

Indian Pacing and Electrophysiology Journal, 2019
Background: Catheter ablation provides curative treatment for tachyarrhythmias. Fluoroscopy, the method used for this, presents several risks. The electroanatomical mapping (MEA) presents a three-dimensional image without using X-rays, and may be adjunct

Characterization of AF Recurrence and Substrate Health by Electrographic Flow (EGF) Consistency in EGF Mapping

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Electrographic flow (EGF) mapping is an FDA 510(k)‐cleared method for visualizing atrial activation wavefronts in atrial fibrillation (AF). Its clinical efficacy in detecting AF sources was demonstrated in the FLOW‐AF randomized controlled trial, and the underlying machine learning strategy used to develop and refine EGF source ...

Successful ablation of frequent atrial premature beats from non-coronary aortic cusp with remote magnetic navigation

Indian Pacing and Electrophysiology Journal, 2015
A 59-year-old female with structurally normal heart was admitted to our hospital for treatment of highly symptomatic, drug refractory atrial premature beats (APB). ECG revealed atrial parasystolic trigeminy.

Clinical Outcomes After Catheter Ablation in Patients With Structural Heart Disease and Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction In patients with ischemic cardiomyopathy (ICM), recurrent VF may be treated with catheter ablation by targeting triggering premature ventricular complexes (PVCs) and/or ventricular scar homogenization. Data on optimal ablation strategies in patients with non‐ischemic cardiomyopathy (NICM) remain limited.

Iatrogenic intra-atrial macro-reenterant tachycardia following transcatheter closure of atrial septal defect treated by radiofrequency ablation

Annals of Pediatric Cardiology, 2011
Percutaneous closure of an atrial septal defect (ASD) has been established as a safe and effective alternative to surgical management. We describe a case of a 41-year-old patient in whom an Amplatzer septal occluder device was used to close a moderately ...

Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Electrogram peak‐to‐peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography–derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained with omnipolar, bipolar, and unipolar mapping.

Epicardial Electrical Activation During Atrial Fibrillation

JACC: Case Reports, 2019
High-definition mapping of atrial fibrillation is most commonly performed from the endocardial surface. This report describes an example of a case in which combined mapping of the endocardium and epicardium of the left atrium demonstrated electrical ...

First United States Experience With Focal Pulsed‐Field Ablation Using the FARAPOINT Catheter for Refractory Ventricular Tachycardia

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Drug‐refractory ventricular tachycardia (VT) after failed radiofrequency (RF) ablation remains a clinical challenge. Pulsed‐field ablation (PFA) is expanding to ventricular applications, but United States experience with focal pulsed‐field‐only catheters in VT is sparse, and pulsed‐field platforms are not equivalent across ...
