Does urgent valve replacement improve survival in patients with acute dysfunction of Starr-Edwards mitral prostheses?
Acute dysfunction of Starr-Edwards mitral prostheses due to thrombus can present with sudden dyspnea without warning signs, and urgent valve replacement may be life-saving.
Case series of acute Starr-Edwards mitral thrombosis shows poor surgical survival; leaves open optimal management strategy.
Four cases of acute dysfunction of Starr-Edwards mitral prostheses are recorded. The patients presented with sudden dysponea 4 to 18 months after apparently successful mitral valve replacement. The prosthetic valve dysfunction was caused by thrombus on the bare metal cage of the prosthesis. No warning thromboembolic phenomena had been recorded. Urgent replacement of the valve resulted in the survival of one patient.
