Results:
In total, 355 patients underwent MVR at our center, of whom 174 received
a bioprosthesis and 181 received a mechanical prosthesis. The use
of anticoagulation among young
women with mechanical prosthesis was associated with a remarkable risk
of postoperative bleeding, abortion, and increased frequency
of pregnancy-related complications (p < 0.0001). In contrast,
there was a considerable survival
benefit for those who received bioprosthesis (p = 0.0001).
Conclusions :
Our data confirm that the use of mitral bioprosthesis in young
women who desire to become
pregnant is safe, reduces complications, and increases survival.
