Cardiac Resynchronization Therapy Devices (CRT)

Cardiac Resynchronization Therapy Devices (CRT) are cardiac electrophysiology (EP) systems that include a small electronic device that is surgically implanted into a pocket of skin to help both ventricles contract together. They are also called biventricular pacemakers. These systems can be used for pacing only, or can include a built-in defibrillator.

The Bluegrass Vascular Surfacer System is designed to reliably, efficiently and repeatedly gain central venous access by inserting the Surfacer System through the right femoral vein and navigating it up through the patient’s venous system with an exit point in the right internal jugular vein, the optimal location for placing a central venous catheter.

Medtronic is recalling some of its implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy (CRT-D) devices because of an unexpected and rapid decrease in battery life. The company said this is due to a short circuit and will cause some devices to produce a “Recommended Replacement Time” (first warning that the battery is low) earlier than expected. Some devices may progress from “Recommended Replacement Time” to full battery depletion within as little as one day.

The new ACC Electrophysiology (EP) Device Implant Registry, part of the National Cardiovascular Data Registry (NCDR) will include data on implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) procedures previously captured in the NCDR ICD Registry, as well as provide the flexibility to capture novel pacemaker procedures. The registry is aligned with the ACC’s Electrophysiology Accreditation program, fully supporting the program’s data requirements.

Integrating data from an array of implantable EP devices from different vendors can be difficult or require disconnected silos of data for different vendors. One solution that was recently introduced to integrate data from various vendors is the Optimize EP software, which allows viewing data from all device vendors in one platform to streamline workflows.

Earlier this year, Medtronic began a worldwide pivotal study evaluating its investigational Extravascular Implantable Cardioverter Defibrillator (EV ICD) system to treat dangerously fast heart rhythms. The EV ICD system is designed to deliver lifesaving defibrillation and pacing therapy via a device the same size as traditional, transvenous ICDs, but with a lead (thin wire) placed outside the heart and veins. The future of CRM device technology.

FDA Approves Barostim Neo System for Advanced Heart Failure Patients. Similar to a pacemaker, the Barostim Neo System uses a pulse generator implanted below the collar bone with a lead that attaches to the carotid artery in the neck. It delivers electrical impulses to baroreceptors in the neck, which sense how blood is flowing through the carotid arteries and relays information to the brain. The brain, in turn, sends signals to the heart and blood vessels that relax the blood vessels.
