Researchers examined data from more than 21,000 patients treated from 1997 to 2018, publishing their findings in the Journal of the American Heart Association.

“These findings are highly pertinent in a clinical setting," researchers explained. 

To date, the company has raised $42 million to develop its transcatheter mitral valve repair system.

“Cardiothoracic imaging continues to evolve, fueled by technical innovations such as dynamic chest radiography, digital tomosynthesis and dark-field radiography," one radiologist said.

Asian patients are rarely represented in large TAVR trials, the authors wrote, so they focused on nearly 1,200 patients from South Korea to provide a fresh perspective. 

João Cavalcante, MD, spoke at RSNA 2023 about key topics and tried to get more radiologists interested in cardiac imaging.
