“This was a true milestone for research on xenotransplantation," one specialist said. The full analysis is scheduled to be presented at the American Heart Association's Scientific Sessions 2022 in Chicago.

The study's authors examined data from nearly 10,000 patients for a new meta-analysis, presenting their findings in JTCVS Open.

The group—which includes engineers, cardiologist, radiologists and other specialists—will attempt to perform a robotic-controlled left atrial appendage occlusion (LAAO) on a patient inside an MRI scanner.

Researchers examined data from 82,000 TAVR patients, focusing on echocardiography-defined PPM. They shared their results in JACC: Cardiovascular Imaging.

The recall is due to a malfunction risk that could, if not handled properly, cause the pump to stop working for a long period of time. This could lead to a serious injury or death, according to the recall. 

“This procedure potentially solves the problem of a growing valve,” the lead surgeon said. “If we can eliminate the need for multiple open-heart surgeries every time a child outgrows an old valve, we could be extending the life of that child by potentially decades or more.”

Researchers tracked data from more than 2,000 patients, noting that surgical bailout, infective endocarditis and paravalvular leak were the most common reasons for surgery to be required after TAVR. The full study was published in the American Journal of Cardiology.

The standard-of-care thinking on TAVR has shifted from getting a valve implanted and managing immediate complications to looking decades down the road and considering the patient's long-term health.
