Open heart surgery for thrombosis of a prosthetic mitral valve during pregnancy. Fetal hydrocephalus.
Pregnant women with cardiac valvular prostheses present an important risk factor and the major complications are endocarditis and thromboembolism. Thromboembolism is determined by a hypercoagulation state. Compulsory anticoagulation treatment is an associated risk factor producing maternal and fetal complications. Different open heart surgical cases during pregnancy have been reported and a review of the literature shows favourable maternal prognosis. A 30-year-old woman with a Björk-Shiley mitral prosthesis, during the 6th week of pregnancy presented with thrombosis and embolism due to a change in anticoagulation treatment from acenocumarol to heparin. Open heart surgery was carried out and the patient's course was favourable. A fetal hydrocephaly of unknown etiology was discovered during the 18th week of pregnancy. Open heart surgery during pregnancy and the necessity of thromboembolic prophylaxis, have been analysed and revised.
