Notes:
1.  Data does not include results from double valve replacement.
2.  Nf = number of patients followed (reproduced from Figure 2); Nd = number 

of patients for which NYHA data were collected (not including missing).

3.  n = number of patients in each category.
4.  Undetermined means data were collected but Class could not be 

determined during exam

5.  Missing refers to the difference between the number of patients followed, 

Nf, and the number of patients for which NYHA data were collected, Nd.
