Former LAPD Office Successfully Undergoes Procedure Using Roto-Rooter-Like
Device to Pulverize Calcified Plaque Caused by Coronary Artery Disease

LOS ANGELES, Dec. 12, 2013 /PRNewswire-USNewswire/ -- William Dumbauld, a
75-year old Rossmoor (Los Alamitos) resident and retired Los Angeles Police
Department officer, is no stranger to life-threatening heart maladies. Having
endured the passing of both parents and several aunts and uncles to heart
attacks, Dumbauld did not want to suffer a similar fate after being diagnosed
with Coronary Artery Disease (CAD). In 2010, he underwent a stent procedure
for one blocked artery and was recently diagnosed with another blockage in a
different artery after taking a nuclear stress test. With the artery being
nearly 80 percent blocked, his long-time cardiologist, Dr. Guy Mayeda of Good
Samaritan Hospital, recommended a new device called the Diamondback 360^®
Coronary Orbital Atherectomy System (OAS) to sand and pulverize the large
amount of calcification that had formed.


Spearheaded by Dr. Mayeda, the Heart & Vascular Center at Good Samaritan
Hospital recently became the first facility on the West Coast to use the
Diamondback 360^® Coronary OAS from Cardiovascular Systems, Inc. (CSI). This
technology is the first evidence-based, safe device approved by the FDA for
treating severely calcified coronary lesions.

Coronary Artery Disease (CAD) is a life-threatening condition and leading
cause of death in men and women in the United States. CAD occurs when a fatty
material called plaque builds up on the walls of arteries that supply blood to
the heart. The plaque buildup causes the arteries to harden and narrow
(atherosclerosis), reducing blood flow. The risk of CAD increases if a person
has one or more of the following: high blood pressure, abnormal cholesterol
levels, diabetes, or family history of early heart disease. According to the
American Heart Association, 16.3 million people in the United States have been
diagnosed with CAD.

The Diamondback 360^® Coronary OAS uses a patented combination of differential
sanding and centrifugal force to reduce arterial calcium that can cause
complications when treating CAD. Arterial calcium is a common occurrence in
patients with severe vascular disease, with moderate to severe arterial
calcium present in nearly 40 percent of patients undergoing a percutaneous
coronary intervention in the U.S.

"This new technology provides patients undergoing coronary intervention on
severely calcified arteries the first ever treatment approved by the FDA for
this high risk patient population," explains Dr. Mayeda. "For patients like
Mr. Dumbauld, this Roto-Rooter-like device helps the cardiologist safely
remove most of the calcium build-up and thereby facilitate both the delivery
and expansion of a stent within the blocked coronary artery."

The Diamondback 360^® Coronary OAS is an eccentrically mounted 1.25-millimeter
diamond-coated crown that sands away calcium in severely calcified coronary
arteries, enabling stent deployment. As the crown rotates and its orbit
increases, centrifugal force presses the crown against the lesion, reducing
arterial calcium, while healthy tissue flexes away.

Dr. Mayeda successfully performed Mr. Dumbauld's procedure in less than 60
minutes on December 9, 2013. He was released from the hospital the next day
with his wife Karen still holding him to his promise that they will begin
taking ballroom dancing lessons once he is fully recovered.

"I felt better right after the procedure and recommend it to anyone who is a
candidate," says Dumbauld. "My wife and I are looking forward to travelling to
Europe and taking our first ballroom dancing lesson."
