In an effort to identify the determinants of survival following reoperation
on patients with prosthetic cardiac valves, the experience with a group of
33 patients at the University of Rochester Medical Center was reviewed. The
survival rate was 58% (19/33). Survival was not related to the valve
involved, the age of the patient, or the technical hazards of a second
cardiac operation. Ten (77%) of the 13 patients in New York Heart
Association (NYHA) Functional Class II survived compared with 8 (40%) of
the 20 in Class III or IV. The survival rate for patients with a
paravalvular fistula was 79% (11/14); with valve dysfunction, 50% (6/12);
and with prosthetic valve infection, 29% (2/7). The determinants of
survival seem to be similar to those for primary operation (i. e., NYHA
patient classification and indication for operation) and less related to
the potential operative complications of a reoperation.
