Percutaneously implanted devices designed to seal off the left atrial appendage (LAA) have been around for some time, but a recent study of surgical closure of the appendage might have a beneficial effect on sales of these devices despite that the study did not deal directly with these devices. The results were compelling enough to provoke a halt to the study before all patients had reached the projected term of follow-up, and at least one observer said it may be time to study whether more routine use of devices for percutaneous LAA closure is indicated.

Two-year results from the Evolut Low Risk Trial show Medtronic plc’s Evolut transcatheter aortic valve replacement (TAVR) is noninferior to open-heart surgery in younger, healthier aortic stenosis patients. Moreover, the Evolut cohort fared better on certain critical events. Specifically, two-year rates of all-cause mortality or disabling stroke were 4.3% for TAVR patients vs. 6.3% for those undergoing surgical aortic valve repair (SAVR).

HONG KONG – Dia Imaging Analysis Ltd. has teamed up with Sonoscape Medical Corp. to deliver cardiac ultrasound artificial intelligence (AI) solutions. The partnership aims to reduce the variability associated with manual or visual analysis, and increase efficiency and accuracy throughout the analysis process. As a result, China-based Sonoscape's ultrasound devices will be offering a layer of automated AI-based analysis to support the clinician’s decision-making process, courtesy of Dia's AI-based cardiac solutions.

HONG KONG – Ultrasight Ltd. has closed a $13 million series B funding round, and is a step closer to entering the clinic in the U.S. with its cardiac ultrasound software. With the funds in hand, Rehovot, Israel-based Ultrasight aims to start clinical trials in the U.S. for its artificial intelligence (AI)-guided software for cardiac ultrasound.

Egnite Inc. emerged from stealth mode in February 2021 with the goal of combining data analytics and digital health technology to illuminate and solve persistent issues in the diagnosis and treatment of structural heart disease. Three months later, it has added artificial intelligence (AI) to its flagship solution, Cardiocare, to drive better diagnosis of aortic stenosis and help physicians predict patient outcomes.

The FDA’s Arthritis Advisory Committee panelists groped through cloudy data while complaining about the design of the phase III trial for Chemocentryx Inc.’s avacopan, and after going overtime ended up without consensus. Briefing documents ahead of the meeting darkened what had been a fairly bright picture for the complement C5a receptor inhibitor for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, but Wall Street held out hope. Wainwright analyst Edward White opined in a May 5 report that the adcom’s outcome “could still be positive,” and a May 4 dispatch from Canaccord Genuity’s Michelle Gilson said the briefing docs “miss[ed] the big picture.”

Acutus Medical Inc. appears to have solved one of the more vexing problems in cardiology, the sheer persistence of persistent atrial fibrillation despite treatment. In a study recently published in Heart Rhythm, the Carlsbad, Calif.-based company demonstrated that 73% of patients undergoing ablation using the new pulmonary vein isolation plus core-to-boundary guided approach experienced acute termination of AF after one procedure, compared to 10% of patients undergoing ablation with the traditional posterior wall isolation approach.
