Less Invasive Aortic Stenosis Treatment

(Ivanhoe Newswire) -- Aortic stenosis is associated with a high rate of death if left untreated. Some patients though are put at too much risk for traditional treatment, so scientists have developed a new and less invasive method for those patients.

Transcatheter aortic-valve replacement treats aortic stenosis by replacing the original valve with a bioprosthetic valve.

In this study, 699 patients with severe aortic stenosis were enrolled in the trial. 23-percent were considered high risk and were given the transcatheter aortic-valve replacement.

The results showed that the patients with aortic stenosis who were candidates for surgical aortic-valve replacement and underwent transcatheter aortic-valve replacement had an improvement of 20-percent in the 1-year survival rate and also had reduced symptoms.

The transcatheter replacement allows for shorter intensive care unit stays. At 30 days after the surgery, the benefits were greater than they were for the traditional treatment.
