Successful ablation of morphology-changing premature ventricular contractions under the guidance of local voltage potentials: A case report

Frontiers in Cardiovascular Medicine, 2023
Premature ventricular contractions (PVCs) stemming from the aortic sinus cusp often have preferential conduction to two exits in the outflow tract and exhibited two different morphologies of PVCs, which may render radiofrequency catheter ablation (RFCA ...

Case Report: A Rare Case of Severe Coronary Venous Spasm During Radiofrequency Ablation of Premature Ventricular Contraction

Frontiers in Cardiovascular Medicine, 2022
Coronary venous spasm has never been reported during premature ventricular extrasystole ablation. We report a 20-year-old female patient who experienced a severe spasm of the great cardiac vein during radiofrequency ablation for premature ventricular ...

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]

, 2019
Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

Anti-adrenergic effects of endothelin on human atrial action potentials are potentially anti-arrhythmic [PDF]

, 2006
Endothelin-1 (ET-1) is elevated in patients with atrial fibrillation (AF) and heart failure. We investigated effects of ET-1 on human atrial cellular electrophysiological measurements expected to influence the genesis and maintenance of AF.
