Abstract
A woman with double outlet left ventricle (DOLV) had undergone a Rastelli operation using a prosthetic Björk Shiley valve and who was receiving anticoagulant drug delivered a healthy male infant. Oral warfarin was replaced by heparin from the 5th to the 13th week of gestation and for the last 5 weeks of gestation. Successful pregnancy in patients with DOLV after a Rastelli operation using a prosthetic valve is possible with careful maintenance. (Circ J 2004; 68: 501 - 503)
