Catheter Ablation

CHICAGO — For patients with atrial fibrillation and obesity, lifestyle modification plus antiarrhythmic drug therapy conferred various benefits but was inferior to catheter ablation for preventing recurrent AF, researchers reported.

CHICAGO — Catheter ablation improved outcomes compared with antiarrhythmic drug therapy in patients with ventricular tachycardia and ischemic cardiomyopathy, researchers reported at the American Heart Association Scientific Sessions.

Medtronic announced the FDA approval of its mapping and dual-energy catheter ablation system for the treatment of persistent atrial fibrillation and radiofrequency ablation of cavotricuspid isthmus-dependent atrial flutter.

Atrial fibrillation is a complex disease with ever-increasing treatment options, such as ablation, and advanced electrophysiology fellowship training is key to improving long-term outcomes, according to a new consensus statement.

The American Heart Association Scientific Sessions will be held in-person only in Chicago from Nov. 16 to 18 and will feature eight late-breaking science sessions during the 3-day meeting.

In patients with atrial fibrillation and heart failure with reduced ejection fraction, cryoballoon ablation was noninferior to radiofrequency ablation, according to the results of the CRABL-HF trial.

Catheter ablation for atrial fibrillation was associated with lower incidence of hospitalization for worsening HF vs. drug therapy in patients with HF with preserved ejection fraction, researchers reported.

PHILADELPHIA — Adults with obesity and atrial fibrillation treated with liraglutide plus risk factor modification had improved outcomes after catheter ablation compared with those prescribed risk factor modification alone.

The American College of Cardiology and the American Heart Association have updated their atrial fibrillation guideline to highlight early rhythm control and prevention strategies.

An updated guideline on the prevention and management of atrial fibrillation includes a new staging system to emphasize disease progression, along with updated recommendations for catheter ablation and left atrial appendage occlusion.
