Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

The U.S. Food and Drug Administration (FDA) has granted the first pediatric indication for use for an implantable cardiac monitor to Medtronic. The Linq II Insertable Cardiac Monitor (ICM) system is the first such device receive 510(k) clearance for use in pediatric patients over the age of 2 who have heart rhythm abnormalities and require long-term, continuous monitoring.

FDA grants new pediatric indication for Medtronic Linq II implantable cardiac monitor 

The FDA granted the first pediatric indication for an implantable cardiac monitor. The Linq II can be used in pediatric patients over the age of 2 for up to 4.5 years of long-term, continuous monitoring.

HFpEF patients with MR may face a higher mortality risk—but not if they have AFib

There is an established connection between MR and HFrEF, but we know much less about the link between MR and HFpEF.

FDA approves trial for new type of thermal-ablation system to treat ventricular arrhythmias

The FDA has approved a clinical trial to evaluate the safety and efficacy of a new type of ablation catheter for patients with ventricular tachycardia (VT) resistant to conventional anti-arrhythmic drugs or standard ablation procedures.

Watchman FLX left atrial appendage closure (LAAC)

Boston Scientific gains a new FDA approval for Watchman FLX LAAC device

The company can now update its labeling instructions for the device to include a new 45-day dual anti-platelet therapy treatment option when treating non-valvular atrial fibrillation.

New expert guidelines highlight the importance of quickly diagnosing and treating CIED infections

Though removal of the affected CIED is typically the smartest treatment option—and one supported by specialty groups all over the world—a majority of patients keep living with the device, often resulting in hospitalization or even death.

Affera Inc Medtronic $925 million catheter ablation atrial fibrillation (AFib)

Medtronic completes acquisition of heart rhythm tech company in a deal reportedly worth $925M

Affera’s portfolio includes interventional solutions such as the Affera Prism-1 mapping and navigation platform, designed to help electrophysiologists diagnose heart rhythm issues, and the Sphere-9 cardiac ablation catheter.

Rethinking arrhythmias: Women may face a higher AFib risk than men

New research, published in JAMA Cardiology, challenges the common belief that AFib is more likely to develop among men than women. The key problem, it seems, is that prior research teams did not understand the significance of certain risk factors.
