Implication

Reoperations involving mechanical valves may warrant heightened perioperative caution; this Level 3 finding leaves open optimal prosthesis selection pending prospective data.

Structured PICO

Does reoperation for mechanical prosthetic valve dysfunction increase hospital mortality compared to bioprostheses in patients requiring reoperation?

P
Population
154 patients (89 men and 85 women) requiring 160 reoperations for prosthetic heart valve dysfunction. Mean age 38.8 years. Primary operations included mitral valve replacement (n=105), aortic valve replacement (n=20), and both (n=29).
I
Intervention
Reoperation for mechanical prosthetic heart valve dysfunction
C
Comparator
Reoperation for bioprosthetic heart valve dysfunction
O
Outcome
Hospital mortality ratehard clinical

Reoperation for mechanical valve dysfunction is associated with higher hospital mortality than bioprosthetic valve reoperation, largely driven by valve thrombosis and monoleaflet mechanical valves.
