Abstract

Background: The management of pregnant patients with mechanical heart valves remains challenging because there are no large randomised studies to provide guidelines for effective anticoagulant therapy. Both vitamin K antagonists and heparins may be associated with maternal and foetal adverse events.

Method: The Southern African Society of Thrombosis and Haemostasis reviewed available literature and comprehensive evidence-based guidelines for the anticoagulation of pregnant patients with mechanical heart valves. A draft document was produced and revised by consensus agreement. The guidelines were adjudicated by independent international experts to avoid local bias.

Results and conclusion: We present concise, practical guidelines for the clinical management of pregnant patients with mechanical heart valves. Recommendations reflect current best practice which will hopefully lead to improved anticoagulation practice in this select group of high risk patients.
