Outcomes of Non‐Paroxysmal AF Undergoing Ablation Guided by a Novel High‐Density Panoramic Cycle‐Length Mapping System

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Catheter ablation is a current therapeutic approach for atrial fibrillation (AF). However, the efficacy for non‐paroxysmal AF remains suboptimal. Objective We hypothesize that the novel panoramic cycle‐length mapping (CLM) system can guide the pulmonary vein (PV) isolation and additional potential AF drivers.

Pulse Field Ablation for Persistent Atrial Fibrillation: Targeting the Persistent Superior Vena Cava

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that can act as a trigger for atrial fibrillation (AF). Thermal ablation in this region carries a notable risk. Pulse field ablation (PFA), a non‐thermal modality, offers a safer alternative.

Left atrial longitudinal strain by speckle tracking as independent predictor of recurrence after electrical cardioversion in persistent and long standing persistent non-valvular atrial fibrillation

The International Journal of Cardiovascular Imaging, 2019
Atrial fibrillation (AF) is the most common arrhythmia in humans. After successful cardioversion, there is a recurrence of 60% due to atrial remodeling, and it has been shown that the global peak atrial longitudinal strain (GPALS) is decreased in these ...

Prediction of sinus rhythm maintenance following DC-cardioversion of persistent atrial fibrillation – the role of atrial cycle length

BMC Cardiovascular Disorders, 2006
Background Atrial electrical remodeling has been shown to influence the outcome the outcome following cardioversion of atrial fibrillation (AF) in experimental studies. The aim of the present study was to find out whether a non-invasively measured atrial

Simulation of overdrive pacing in 2D phenomenological models of anisotropic myocardium [PDF]

, 2017
Spiral waves in the heart underlie dangerous cardiac arrhythmias such as fibrillation. Low-voltage defibrillation and cardioversion are modern methods to treat such pathologies. This type of electrotherapy is based on the phenomenon of superseding spiral
