REMINDER: ORLive Presents: Innovative Techniques to Remedy Blood Vessel Blockage Resulting From Peripheral Arterial Disease

Live Webcast: From Memorial Hermann Heart & Vascular Institute-Southwest: May 2, 2007 at 5:30 PM CDT (22:30 UTC)

HOUSTON, TX -- (MARKET WIRE) -- May 2, 2007 -- During a live global Webcast on from Memorial Hermann Heart & Vascular Institute in Houston, Texas, on May 2, at 5:30 PM CDT, cardiologists Sherman Tang, M.D., and Carlos Zorrilla, M.D., will demonstrate an innovative non-surgical treatment to clear blocked arteries caused by peripheral arterial disease, or PAD. In the groundbreaking procedure, doctors use CryoPlasty® Therapy to remedy difficult-to-treat blood vessel blockage. The cooling therapy causes less trauma to the blood vessels and has a lower incidence of restenosis -- reclogging of an artery that can call for repeat surgery.

During the procedure, a balloon is delivered to the lesion and inflated with nitrous oxide gas, or laughing gas. The vessel wall is then cooled with a 20-second treatment at -10ºC. The technique gently cools and opens arteries clogged with plaque caused by PAD. The treatment simultaneously dilates and treats atherosclerotic plaque.

"CryoPlasty® Therapy offers hope to people with severely blocked below-the-knee arteries. These blockages, which are particularly common in diabetics, can reduce blood flow to the legs and feet, putting people at risk for infection, leg ulcers, gangrene and amputation," said Dr. Tang.

In traditional angioplasty, a catheter is used to advance a tiny balloon to the site of the blockage. The balloon is then filled with saline, compressing the walls of the clogged artery to open it and allow blood flow.

"Angioplasty is minimally invasive and initially works very well, but studies show it can also cause scarring of the artery wall that can prompt the artery to close," added Dr. Zorrilla.

About 10 million people in the United States suffer from PAD. Only one in four are receiving treatment. PAD commonly affects people who are 65 or older but can also be found in diabetics of any age.

PAD can be associated with coronary disease, cerebrovascular disease, aneurysms, increased mortality and reduction of quality of life. Patients with objectively documented PAD have a four- to six-fold increase in cardiovascular mortality over healthy age-matched individuals.

Serving as online moderators during the live Webcast will be cardiologists David A. Portugal, M.D., and cardiologist Ramon Ty, M.D. The moderators will receive e-mailed questions from viewers worldwide and relay them to Drs. Tang and Zorrilla, who will answer selected, appropriate inquiries during the surgery. The Webcast will be available for online viewing for at least one year, and Drs. Tang and Zorrilla will continue to receive and answer e-mailed questions for one week following the surgery.

The program is the twelfth in a series sponsored by Memorial Hermann Healthcare System, giving medical professionals and consumers the opportunity to view innovative surgical procedures live on the Internet from anywhere in the world.
