Key result
Emergent reoperation for prosthetic valve obstruction carries ~18% in-hospital mortality.
Why the study?
The incidence and outcomes of mechanical valve obstruction in Yemeni patients with rheumatic heart disease were not well characterized despite high morbidity and mortality.
Population
129 patients undergoing reoperation for obstructive mechanical valve out of 2794 prosthetic valve replacements in Yemen
Comparison
Urgent reoperation for prosthetic valve obstruction
Design
Observational cohort study at a single center
Follow-up
In-hospital

High mortality with emergent reoperation warrants caution; leaves open optimal strategies for prosthetic valve thrombosis in similar settings.
Observational (n=129)
No
In Yemeni patients with mechanical valve obstruction, the vast majority of cases are due to thrombosis and urgent reoperation carries a high in-hospital mortality of 17.8%.
Al‐Motarreb et al. (2010) conducted an observational in Prosthetic valve obstruction (n=129). Emergent reoperation for prosthetic valve obstruction was evaluated on In-hospital mortality. Emergent reoperation for prosthetic valve obstruction in Yemeni patients was associated with an in-hospital mortality rate of 17.8%.
