The Role of Electrophysiologic Study in Device Selection for Leadless Atrial Pacing [PDF]

Texas Heart Institute Journal
The AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing ...

Into a Fluoroless Future: an Appraisal of Fluoroscopy-Free Techniques in Clinical Cardiac Electrophysiology [PDF]

Current Cardiology Reports, 2021
Abstract Purpose of Review There are risks to both patients and electrophysiology providers from radiation exposure from fluoroscopic imaging, and there is increased interest in fluoroscopic reduction. We review the imaging tools, their applications, and current uses to eliminate fluoroscopy.

Advanced imaging for risk stratification for ventricular arrhythmias and sudden cardiac death

Frontiers in Cardiovascular Medicine, 2022
Sudden cardiac death (SCD) is a leading cause of mortality, comprising approximately half of all deaths from cardiovascular disease. In the US, the majority of SCD (85%) occurs in patients with ischemic cardiomyopathy (ICM) and a subset in patients with ...

Bipolar ablation’s unique paradigm: Duration and power as respectively distinct primary determinants of transmurality and steam pop formation

Heart Rhythm O2, 2020
Background: Bipolar radiofrequency (RF) ablation strategies are increasingly used, mainly to target deep myocardial reentrant circuits responsible for ventricular tachycardia that cannot be extinguished with traditional unipolar RF ablation. Because this
