A 69-year-old woman, who had undergone mitral valve replacement, developed
acute congestive heart failure and was transferred to our institution.
Cineradiography demonstrated that two leaflets of the St. Jude Medical
valve were stuck in a closed position. Emergency redo mitral valve replacement
was performed with a CarboMedics valve. Postoperative hematological studies
yielded a diagnosis of antiphospholipid syndrome. Although postoperative
anticoagulant therapy was performed more carefully than usual, the prosthesis
became stuck again. Therefore, a third operation was performed using a
tissue prosthesis. We concluded that mitral valve plasty should be a first
option for patients with antiphospholipid sysdrome undergoing mitral valve
surgery. Should prosthetic valve replacement be required, a tissue prothesis
world be best.
