Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

Interventional cardiologists, electrophysiologists ask CMS to clarify policy after unexpected denials

Three cardiology societies have reached out to CMS with questions about how MACs are interpreting a policy related to shared decision-making. 

FDA approves Abbott’s Aveir dual chamber (DR) leadless pacemaker system, the world’s very first dual chamber leadless pacing solution for treating patients with abnormal heart rhythms.

FDA approves world’s first dual-chamber leadless pacemaker system

The minimally invasive system is made up of two pacemakers that send signals back and forth to one another. One pacemaker is placed on the patient's right ventricle, and the other is placed on the patient's right atrium. 

Shockwave Medical's intravascular lithotripsy used during transvenous lead extraction

Intravascular lithotripsy helps address the challenges of transvenous lead extraction

Dense calcifications have long been viewed as one of the most challenging aspects of TLE procedures. IVL may offer specialists a new way to address that issue.
