Three pregnancies with mechanical heart valve and no follow-up in 10 years.
J Coll Physicians Surg Pak Jan ;17(5):292-3.

Anticoagulation and proper INR (International Normalized Ratio) monitoring is essential for patients having mechanical heart valves; it is vital in these patients in order to prevent lethal complications such as valve thrombosis and systemic embolism. In pregnancy, it becomes even more important as pregnancy itself is a hypercoagulable state. This report describes a female patient having undergone mitral valve replacement with a Starr Edward metallic prosthesis. She came back to the operating surgeon after 10 years of valve replacement with a history of three uneventful healthy deliveries and no follow-up and INR monitoring during this period.
