Human menopausal gonadotropin-induced bioprosthetic valve thrombosis.

Bioprosthetic valve thrombosis (BPVT) is a rare but potentially life-threatening complication. Human menopausal gonadotropin (hMG) is commonly used for ovulation induction and has been associated with arterial and venous thrombosis. We reported a case of BPVT related to fertilization in a 39-year-old female, who underwent redo mitral valve replacement.
