Overall actuarial survival curve (at 10 years). The numbers below the time axis indicate patients at risk (at 2-year intervals). (AVR = aortic valve replacement; DVR = double-valve replacement [AVR + MVR]; MVR = mitral valve replacement.)

6. Fig 5
Actuarial curves of freedom from valve-related death. The numbers below the time axis indicate patients at risk (at 2-year intervals). (AVR = aortic valve replacement; DVR = double-valve replacement [AVR + MVR]; MVR = mitral valve replacement.)
