The aortic valve consists of several leaflets (3 most often) which, when they become calcified, prevent it from opening properly. After ultrasound treatment, we see a significant improvement in the opening surface of the aortic valve shown here in the image on the right.

Adobe stock Currently, the treatment of heart valve diseases relies on the replacement of the dysfunctional valve with an artificial prosthesis. However, this procedure cannot be offered to all patients due to its invasive nature. In a new study, a group of researchers from laboratories shared by Inserm, ESPCI Paris, CNRS and Université Paris Cité, in close collaboration with the start-up Cardiawave spin-off of the Georges Pompidou European Hospital and the Paris Medical Physics Laboratory (Inserm/CNRS/ESPCI/PSL), report for the first time the clinical efficacy of a "non-invasive" focused ultrasound therapy. The clinical trial, conducted on a sample of 40 patients, significantly improved their health. Their findings have been published in The Lancet .
