ST. LOUIS (KMOX) — SSM Health Saint Louis University Hospital is the first in Missouri to use a new heart valve replacement technology.

It's called the Lotus Edge Valve.

"Lotus Edge is the latest FDA-approved heart valve to be used in the country," said Dr. Michael Lim, a SLU Care cardiologist at SSM Health Saint Louis University Hospital.  "It is made by Boston Scientific and it is one of three approved products for transcatheter aortic valve replacement known as TAVR."

TAVR is the recently approved non-surgical way to replace a bad aortic valve through a catheter most of the time coming up through the leg. The procedure recently gained expanded approval to be used in patients deemed at low risk for surgical complications. Previously, it had been approved in both high risk and intermediate-risk patients.

"It has a seal in the bottom of the valve which makes sure that there is no area for blood flow to leak from the outflow pipe — which is called the aorta — back into the ventricle," said Dr. Lim. "And so the valve was designed to eliminate that. This valve is also designed to be able to be positioned without a drop in blood pressure and without stress while it's being deployed."

One of the major benefits of this new Lotus Edge Valve is that it is 100% repositionable.

"This is a self-expanding valve where you sort of expand it into its position but it is fully recapturable and repositionable," Dr. Lim tells KMOX.  "So if you get it in position and then determine that position just isn't good enough for the patient, we can capture it and reposition it so that position becomes ideal and something that lends itself to the best possible benefit for the patient over the long run."
