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.

Images from the consensus document showing the proper left atrial appendage (LAA) sizing assessment for a transcatheter occluder device using transesophageal echo (TEE). Sizing and evaluation for pre-existing thrombus in the LAA also can be performed using cardiac CT.

One of the new recommendations is to conduct baseline imaging with TEE or cardiac CT.

Pulsed-field ablation could be the next big EP technology trend

Atul Verma, MD, director of cardiology at McGill University Health Centre in Montreal, explained why the late-breaking PULSED-AF trial data on Medtronic’s pulsed-field ablation technology is so important for cardiologists.

Pulsed-field ablation for AFib not linked to any signs of bronchial damage

As this new ablation technique continues to gain momentum, researchers are hoping to learn as much as possible about any potential side effects.

Low BMI increases risk of cardiac tamponade during AFib ablation

Also, researchers noted, cryoballoon ablation was linked to a lower risk of cardiac tamponade than radiofrequency ablation. The study included data from nearly 60,000 hospitalizations.
