New Options for Aortic Valve Replacement

Epidemiological studies have determined that more than one in eight people aged 75 and older have moderate or severe aortic stenosis (AS).1 A study observed that many symptomatic patients with severe AS are not referred to a heart team for valve replacement evaluation.2 Surgical aortic valve replacement (SAVR) is the gold standard for treatment of severe AS and transcatheter aortic valve implantation (TAVI) offers a new treatment option for patients considered high risk for surgery.
Here is how you can help.

Aortic Valve Disease is Common in Elderly Patients

“Valvular heart diseases represent an underappreciated yet serious and growing public health problem that should be addressed.”

Prevalence of Valvular Heart Disease by Age1
Prevalence of Valvular Heart Disease by Age

As the chart illustrates, aortic valve disease is common and its prevalence increases with age. For people over the age of 75 years, the prevalence of aortic stenosis is 3%. More than one in eight people over the age of 75 have moderate or severe valve disease.1 As the population ages, this condition becomes an important public health problem.1
