Challenges in the management of patients with mechanical prosthetic heart valves during pregnancy

Abstract

To the editor, We have recently read with great interest the article by Kai et al. entitled “Pregnancy managed by unfractionated heparin (UFH) after mechanical aortic valve replacement” [1]. The authors have reported the management of a pregnant patient with mechanical prosthetic valve in the aortic position. We congratulate the authors for achieving a successful outcome in such a high-risk patient for prosthetic valve thrombosis (PVT). However, we believe that the anticoagulation therapy proposed by the authors during pregnancy requires further discussion.
