Pacing and Clinical Electrophysiology : PACE; Ekrem Turan O, Yilancioğlu RY et. al.

Jan 29th, 2023 - Atrial tachycardias (AT) are common cardiac arrhythmia disorders for congenital heart disease (CHD) The anatomic substrate that surgical suture lines, scar tissue, or prosthetic material may cause pre-existing atrial conduction abnormalities which...

High-density characterization of the sinus rhythm: a new functional substrate map of sc...
Journal of Interventional Cardiac Electrophysiology : an ... Tsai WC, Lin YJ et. al.

Jan 25th, 2023 - Reentrant atrial tachycardias (ATs) utilize critical isthmus (CI) for the maintenance of the circuit. The electrophysiological characteristics and clinical implications of the targeted CI regions of reentrant ATs during sinus rhythm (SR) were not ...

THERMOCOOL SMARTTOUCH®SF Catheters With Ablation Index Study

Dec 28th, 2022 - The purpose of this study is to measure the long term effectiveness,clinical benefit, and safety outcomes of catheter ablation with STSF and AI for paroxysmal atrial fibrillation (PAF) subjects up to 12-month follow-up. Subject:Up to 150 PAF subj...

Impact of Intravenous Caffeine on Atrial Electrical Properties and Potential Arrythmia Induction

Nov 16th, 2022 - The mechanism by which caffeine might change cardiac electrophysiologic properties is largely unknown. Most of the prior studies conducted have evaluated the correlation based on the premise of oral consumption. One caveat among such study designs...

Ablation of Consecutive Atrial Tachycardia

Nov 10th, 2022 - Ablation of consecutive atrial tachycardia (AT) after ablation of atrial fibrillation (AF) or cardiac surgery can be challenging due to complex substrate and AT mechanisms. A substantial portion of patients is known to show various tachycardias an...

AF Detection by Smartwatch Challenging in Some Patients

Oct 14th, 2022 - The ability of an Apple Watch to detect atrial fibrillation (AF) is significantly affected by underlying ECG abnormalities such as sinus node dysfunction, atrioventricular (AV) block, or intraventricular conduction delay (IVCD), a single-center st...

No advantage shown for LAA ligation as adjunct to pulmonary vein isolation
Ted Bosworth

Nov 15th, 2021 - In patients treated for persistent atrial fibrillation (AFib) with pulmonary vein antral isolation (PVAI), there was a numerical but not a statistical advantage for adjunctive left atrial appendage (LAA) ligation in a multicenter randomized trial.

Novel Mutation May Be Unrecognized Cause of Sudden Infant Death

Aug 24th, 2021 - A previously healthy infant who survived sudden cardiac arrest at home was later found to have a de novo likely pathogenic genetic mutation in the SOS1 gene, which might be an unrecognized cause of sudden infant death, report clinicians from Misso...

VENUS: Vein of Marshall Ethanol Infusion for AF Now Published

Nov 4th, 2020 - The VENUS trial results, which demonstrated a benefit of adding an ethanol infusion to the vein of Marshall during catheter ablation of persistent atrial fibrillation (AF), are now published. The results were first presented in March at the virtua...

Most Patients Free of AF 1 Year After Visually-Guided RF Ablation

Jul 29th, 2020 - One-year results with a radiofrequency balloon catheter to isolate pulmonary veins (PV) when treating paroxysmal atrial fibrillation (AF) show that 84% of patients remained free of AF and nearly as many were free of AF, atrial flutter, or atrial t...
