Aortic root replacement with a Freestyle™
stentless porcine valve (Medtronic Inc.) was performed on a 32-year-old
woman for aortic root aneurysm. The patient had been given a diagnosis
of systemic lupus erythematosus and had been maintained on steroid
therapy for 15 years. Lupus anticoagulant was present and the
anticardiolipin antibody titer was abnormal as follows: IgG, 2.0IU/ml
(normal＜1.0IU/ml). For the patient requiring aortic root reconstruction,
many options are available. The use of a biological valved conduit
should be considered for patients in whom anticoagulation is not
desirable. The Freestyle™ stentless porcine valve offers an
acceptable alternative to mechanical prostheses, especially for cases
with contraindication for anticoagulant therapy, associated with
antiphospholipid antibodies.
