Sadra Medical, a Campbell company developing therapies for aortic valve disease, has raised a $9M first round of round of funding, the company said.

Pequot Ventures co-led the financing, along with the company’s original seed investors Onset Ventures and Schroder Ventures.

As many as three million people in the U.S. have aortic stenosis, the company said, adding that only a small percentage of those are treated with the current standard of care, open-heart surgery using cardiopulmonary bypass.
