Prosthetic valve regurgitation
- Bioprosthetic valve degeneration can result in regurgitation due to leaflet calcification and noncoaptation or leaflet degeneration with a tear or
perforation.
- Even in asymptomatic patients with severe bioprosthetic regurgitation, valve replacement is reasonable because of the risk of sudden
clinical deterioration if further leaflet tearing occurs. The increased risk of a repeat operation must always be taken into consideration.
- The type of valve prosthesis and method of replacement selected for a patient undergoing reoperation depend on the same factors as those for patients
undergoing a first valve replacement.
