Left Atrial Appendage Closure

The left atrial appendage (LAA) of the heart is a common location where clots form in atrial fibrillation (AFib) patients that then embolism and cause a stroke. Closing off the LAA either surgically, with a clip or via transcatheter LAA closure device, closes the opening to the LAA to prevent clots from forming or embolizing. The clots are the reason why AFib patients need to be on anticoagulants. LAA occlusion (LAAO) enables patients to stop taking anticoagulation drugs. LAAO has been a rapidly growing segment of structural heart procedures since the approval of the first device, the Watchman, in 2015. Procedures are performed by electrophysiologists, interventional cardiologist or cardiac surgeons.

Osso VR, a San Francisco-based virtual reality (VR) company, has developed a new VR training simulation focused on left atrial appendage occlusion (LAAO) procedures. The simulation is designed to offer clinicians a new way to practice LAAO procedures in a “repeatable, risk-free virtual environment.”

Cardiologist-approved VR for interventional procedures headed to ACC.24

San Francisco-based Osso VR and the American College of Cardiology have collaborated on advanced LAAO simulations. The two groups first started working together back in 2022.

An updated look at combining LAAO with ablation, TAVR or other interventional heart procedures

Performing two procedures at once does not appear to make a significant impact on patient safety, though it may lead to a few new risks sure to interest heart teams.

ICE-guided Watchman procedures linked to safety concerns—is TEE better for LAAO or will things improve?

TEE and ICE are each associated with certain advantages and disadvantages, researchers explained. The new analysis included data from nearly 40,000 patients.

Learning more about AFib: 19 important topics for cardiologists, other heart specialists to investigate

New AFib recommendations from the American College of Cardiology and American Heart Association covered significant ground—but there is still much more to learn, experts explained.

2024 has been a banner year for structural heart treatments, especially those focused on the tricuspid valve. In February, for example, Edwards Lifesciences made history when its Evoque transcatheter tricuspid valve replacement (TTVR) system became the first device of its kind to gain U.S. Food and Drug Administration (FDA) approval for treating tricuspid regurgitation (TR). Two months later, Abbott’s TriClip transcatheter edge-to-edge repair (TEER) system also gained FDA approval for the treatment of TR.

New AFib guidelines include higher recommendations for catheter ablation, LAAO

Cardiologists, electrophysiologists, surgeons and patient representatives all worked together on the updated guidelines, which were published in both the Journal of the American College of Cardiology and Circulation.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
