Initial experience of transoesophageal echocardiography-guided percutaneous pulsed field ablation of atrial fibrillation

Open Heart

Objective Pulsed-field ablation (PFA) is a new technology of catheter ablation for atrial fibrillation (AF). This research is to investigate the feasibility of a new strategy (transoesophageal echocardiography-guided pulsed field ablation, TEEP) to guide PFA for AF with no contrast and zero fluoroscopy.

Anatomical characteristics of mitral isthmus and its spatial relationship with the esophagus in patients undergoing atrial fibrillation ablation using CT angiography

Frontiers in Cardiovascular Medicine

BackgroundThis study examines the anatomical characteristics of the mitral isthmus (MI) and its spatial relationship with the esophagus in patients undergoing atrial fibrillation ablation, using cardiovascular computed tomographic angiography (CTA).

Ablating VHL in rod photoreceptors modulates RPE glycolysis and improves preclinical model of retinitis pigmentosa

Journal of Clinical Investigation - Cardiology

By ablating VHL in rod photoreceptors and elevating hypoxia-inducible factor (HIF) levels, we demonstrate a path to therapeutically enhancing glycolysis independent of the underlying genetic variant that slows degeneration of both rod and cone photoreceptors in a preclinical model of retinitis pigmentosa.

Shorten the Blanking Period After Atrial Fibrillation Ablation, Experts Say

DAIC

Based on continuous monitoring of early recurrence of atrial tachyarrhythmia immediately after patients have undergone atrial fibrillation ablation, Musat et al. Early recurrence of atrial tachyarrhythmia (ERAT) is commonly seen following catheter ablation of AF, with reported incidences of up to 61% in the first three months.

Pulmonary vein stenosis or occlusion resulting from radiofrequency ablation of atrial fibrillation can be mistakenly diagnosed as pneumonia: a case report

Frontiers in Cardiovascular Medicine

The increased use of radiofrequency ablation (RFA) for atrial fibrillation (AF) has led to a rise in cases of pulmonary vein stenosis or occlusion (PVS/O) as a complication. Clinical signs of PVS/O post-ablation can vary from no symptoms to common respiratory issues like coughing, hemoptysis, shortness of breath, and chest pain.

Instant termination as a novel indicator for prognosis of persistent atrial fibrillation during cryoballoon ablation: a propensity score-matched analysis

Frontiers in Cardiovascular Medicine

BackgroundInstant atrial fibrillation termination (AFT) during radiofrequency ablation has been suggested as a predictor of prognosis in persistent atrial fibrillation (AF). However, its role in cryoballoon ablation remains unclear. Propensity score matching (PSM) was applied to eliminate covariate imbalances. years] were included.

Case Report: Fatal atrioesophageal fistula following atrial fibrillation ablation—critical reflections on prevention

Frontiers in Cardiovascular Medicine

Radiofrequency ablation (RFA) is an important therapeutic modality for atrial fibrillation (AF), widely utilized in clinical practice due to its safety and significant efficacy. This case report describes a unique instance of a patient developing AEF following AF ablation, accompanied by ischemic stroke and myocardial infarction.
