Catheter Ablation: Evolution and Efficiencies

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The present review includes a discussion the goals and pitfalls of efficiency in the medical profession, a historical perspective on the evolution of catheter ablation in the field of electrophysiology (EP), and the data regarding the relationship between efficiency and outcomes in the EP lab. Focus on efficacy is critical to maximize resource

Pacemapping [PDF]

, 2005
Pacemapping (PM) is an electrophysiologic technique designed to help locating tachycardia sources by stimulating at different endocardial sites in order to reproduce the clinical tachycardia characteristics.

Safety and Utility of Smartphone‐Based Heart Monitors in Pediatric Patients With Cardiovascular Implantable Electronic Devices

Journal of Cardiovascular Electrophysiology, EarlyView.
Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...

Terminal S Wave Pattern in Lead V3 as a Simple Marker for Ventricular Tachycardia Risk Stratification in Patients With Repaired Tetralogy of Fallot

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Patients with repaired tetralogy of Fallot (rTOF) remain at risk of ventricular tachycardia (VT). This risk is most commonly related to slow conduction within the septal isthmus, which is defined as the region between the ventricular septal defect (VSD) patch and adjacent valvular annuli.

Radiofrequency catheter ablation of idiopathic ventricular tachycardia originating in the main stem of the pulmonary artery.

, 2002
We report the case of a patient in whom successful radiofrequency catheter ablation of an idiopathic ventricular tachycardia (VT) originating in the main stem of the pulmonary artery was performed. After successful ablation of the index arrhythmia, which

Time‐Dependent Diagnostic Yield and Therapeutic Impact of Implantable Loop Recorders, Brugada Syndrome as the Exception

Journal of Cardiovascular Electrophysiology, EarlyView.
Diagnostic yield and therapeutic impact varied substantially according to the indication for implantation. Actionable diagnoses were concentrated in the early follow‐up period for syncope and palpitations, whereas late atrial fibrillation detection after cryptogenic stroke could still modify antithrombotic management. In contrast, patients with Brugada

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.
