Edwards Lifesciences (EW) - Get Edwards Lifesciences Corporation Report gained more than 6% on Monday after the medical research and device company announced positive results related to its recent aortic valve surgical treatment trial.

Edwards Lifesciences stock gained $10.91 to $190.66 on the New York Stock Exchange after the company on Saturday said its SAPIEN 3 transcatheter aortic valve proved successful in patient trials vs. more traditional open-heart surgery treatment.

"The trial, which compared treatment with the SAPIEN 3 valve to surgery in patients with severe symptomatic aortic stenosis (AS) at low risk of death from surgery, achieved superiority of its primary endpoint at one year," the company said in a statement.

Outcomes between transcatheter aortic valve replacement and open-heart surgery with the SAPIEN 3 valve achieved "a 46% reduction in the event rate for the primary endpoint of the trial, which was a composite of all-cause mortality, all stroke and rehospitalization at one year."
