of intervention after the procedure.

"Some people with severe aortic stenosis, or narrowing of the aortic valve, are not good candidates for open-heart surgery because they may have other medical conditions that would classify them as high risk for surgery," said Dr. Linda D. Gillam of the Columbia University Medical Center in New York, a lead author on the study. "These findings are especially critical for elderly patients who could not survive open-heart surgery."

The study concluded that transcatheter and surgical aortic valve replacement result in comparable improvements in radial strain, strain rate and left ventricular ejection fraction in elderly patients with severe symptomatic aortic stenosis.

LACK OF ADHERENCE TO GUIDELINES FOR SEVERE AORTIC STENOSIS LEAVE SYMPTOMS UNIDENTIFIED AND PATIENTS WITH LIFE-THREATENING HEART CONDITIONS UNTREATED

More than 75 percent of patients studied did not have aortic valve replacement surgery even though they met established criteria

Symptoms of severe aortic stenosis are under-diagnosed, preventing patients from receiving potentially life-saving aortic valve replacement surgery, according to research unveiled at ASE's Scientific Sessions. By using cardiovascular ultrasound and other objective tests, physicians can more accurately diagnose symptoms of severe aortic stenosis and help prevent the rapid progression of the disease.

For this research, physicians examined 106 patients and found that only 25 percent with severe aortic stenosis (AS) were referred for surgery. The other 75 percent did not have valve replacement (AVR) surgery even though they met echocardiographic criteria.

"Patients are not being referred for aortic valve replacement surgery because symptoms of aortic stenosis are not being identified or are not attributed to aortic stenosis. As a result, surgery in
