Overview
The number of patients undergoing aortic valve replacement surgery to treat aortic stenosis has increased progressively over the past 10 years. The surgery is usually performed in elderly patients with preserved ejection fractions. Transcatheter aortic valve implantation (TAVI) represents a new option in patients with no surgical options.
Epidemiology and Demographics
Demographics Among Patients Undergoing Aortic Valve Replacement for Aortic Stenosis
Among the 512 aortic stenosis patients who underwent valve replacement, 54.3% were elderly (more than 70 years), 80% had a preserved left ventricular systolic function (left ventricular ejection fraction >60%) and 85% had symptoms of heart failure (NYHA class II-IV).[1]
Frequency of Aortic Valve Replacement
The number of the aortic valve replacement procedures performed over the last 10 years has increased. Mitral valve surgery was constant during the same period. [2]
