Redo surgery outcomes for obstructed replaced valve: a single-center experience

Prosthetic valve thrombosis is primarily associated with suboptimal anticoagulant therapy and can occur years after valve replacement surgery. The prognosis for redo valve replacement is favorable with a 30-day operative mortality rate of 7.7%. For patients with prosthetic valve thrombosis, direct surgical intervention without prior fibrinolysis may be safe and effective for patients with prosthetic valve thrombosis.
