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 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].
