Anticoagulation during pregnancy in women with prosthetic valves: evidence, guidelines and unanswered questions

摘要

The management of women with mechanical heart valves during pregnancy remains difficult and controversial. There is no ideal anticoagulation regimen for this unique population, as there are inherent risks and benefits of each approach for both mother and fetus. There has been limited data available to guide the clinician in the optimal treatment strategy for an individual patient. The AHA/ACC Guidelines for the Management of Patients with Valvular Heart Disease created class recommendations for this population based upon current evidence, which is summarized in this review.
