SAN FRANCISCO – As the transcatheter aortic valve replacement (TAVR) field matures, it is becoming increasingly difficult to develop a new implant that can distinguish itself vs. competitors. The incremental benefits are narrowing rapidly, making it tough to distinguish new iterations from one another using standard, randomized trials.

SAN FRANCISCO – Mitraclip from Abbott Park, Ill.-based Abbott Laboratories, has long been the only minimally invasive mitral valve repair device that's approved by the FDA. Edwards Lifesciences Corp., of Irvine, Calif., aims to challenge that dominance with its Pascal. This week at the Transcatheter Cardiovascular Therapeutics (TCT) conference, positive one-year data from the small CLASP study on Pascal were presented, offering a further glimpse of data for comparison.

LONDON – The first systematic review and meta-analysis of the accuracy of artificial intelligence in health care has concluded AI may be as good as clinicians in interpreting medical images, but it is hard to be sure because of the poor quality of published studies. Researchers at Birmingham University, U.K. considered 31,887 journal papers appearing between January 2012 and June 2019, of which 20,530 were screened. They found most were methodologically flawed.

Corvia Medical Inc. is enrolling patients in a 100-site multinational study of its Interatrial Shunt Device that will measure traditional heart failure endpoints as well as biosensor data transmitted to the cloud for analysis by Napier, Ill.-based Physiq's artificial intelligence analytics. The trial will evaluate Tewksbury, Mass.-based Corvia's device in heart failure with preserved and mid-range ejection fraction.

BOSTON – The FDA's Center for Device and Radiological Health (CDRH) released draft guidance on Monday aimed at encouraging the use of patient input in medical device clinical trials and helping sponsors understand how they can use patient engagement to improve the design and conduct of investigations.
