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.

Boston Scientific agrees to acquire AFib ablation company

Boston Scientific has scooped up Cortex, a healthcare technology company launched by the venture capital firm Ajax Health in 2023, in a move that will expand its EP offerings.

Heart Rhythm Society launches new group focused on EP advocacy

The new organization, Heart Rhythm Advocates, will urge federal policymakers to pass legislation and support actions that have a positive impact on the future of electrophysiology.

Medtronic's Affera mapping and ablation system with the Sphere-9 catheter

FDA approves Medtronic’s new all-in-one mapping and ablation system for AFib

Medtronic is now the first company to offer two FDA-approved PFA systems for the treatment of persistent AFib. The company’s PulseSelect PFA system gained approval in December 2023. 

Boston Scientific has received U.S. Food and Drug Administration (FDA) approval for its Farawave Nav ablation catheter for the treatment of paroxysmal atrial fibrillation (AFib) and FDA clearance for its new Faraview software

Boston Scientific scores 2 key FDA approvals for PFA mapping technology

The two newly approved technologies are used together to help visualize cardiac ablation procedures performed with Boston Scientific’s Farapulse pulsed field ablation system.

AHA issues a scientific statement on COVID-19 cardiac arrhythmias

The objective of the AHA scientific statement is to review the available evidence on for better management of cardiac arrhythmias from COVID causes that are still encountered on a regular basis.

Cardiologists have performed what they believe to be the world’s first substernal lead extraction, sharing their experience in JACC: Case Reports.[1]The device being extracted, Medtronic’s Aurora EV-ICD, received U.S. Food and Drug Administration (FDA) approval in October 2023.

Cardiologists perform world’s first substernal lead extraction

The 49-year-old patient was not in pain or suffering any complications, but he wished to have his extravascular ICD removed once his symptoms improved. The care team agreed to extract it after a long discussion, and they said it was "easier than expected." 

The OmniaSecure defibrillation lead, which Medtronic describes as “the world's smallest transvenous defibrillation lead,” has a size of just 4.7 French.

Medtronic’s OmniaSecure, the smallest ICD lead of its kind, linked to long-term durability

Reliability modeling suggests the small-diameter defibrillation lead, already linked to positive early outcomes, should last patients for at least 10 years—and likely longer.

Rising heart failure, AFib rates a ‘wake-up call’ for US cardiologists

Today's heart teams already face a number of challenges on a day-to-day basis.  New data suggest they could soon be treating more patients than ever before.
