AB  - Five hundred fifty-two patients underwent a total of 617 reoperations for repair 
      or replacement of a prosthetic heart valve. Operative mortality for first 
      reoperation (530 patients) was 5.9% for the aortic position and 19.6% for the 
      mitral position. Overall operative mortality was 14% for second reoperation (69 
      patients) and 7% for third reoperation (14 patients). In addition to valve 
      position, operative mortality for first reoperation appeared to be related to 
      pre-reoperation functional class and urgency of operation. First reoperation for 
      mitral valve patients in New York Heart Association (NYHA) Class II was 4.2%; for 
      Class III, 9.3%; and for Class IV, 41%. In the aortic position, operative 
      mortality was 2.4% for Class I, 1.6% for Class II, 6.3% for Class III, and 20.8% 
      for Class IV. The mortality for elective mitral valve reoperation was 0%; for 
      urgent operation, 20.3%; and for emergency procedures, 54.5%. Elective aortic 
      valve reoperation carried a 1.4% mortality; urgent procedures, 8%; and emergency 
      procedures, 37.5%. No significant differences in bleeding complications were 
      noted between reoperations and initial valve replacement. The data appear to 
      suggest that when significant valve dysfunction is first noted, reoperation 
      should be undertaken to minimize operative risk.
