Early Versus Late Post Caesarean Section Oral Anticoagulation Initiation and Risk of Maternal Complications in Patients With Mechanical Heart Valve Prosthesis

Summary

A randomized cohort study applied to patients with mechanical heart valve prosthesis who will be delivered by caesarean section at or after 28 weeks of gestation . Using a table of random numbers, participants will be divided into 2 equal groups. Group A (57 patients) in which warfarin will be started day 2 after caesarean delivery (i.e. 24 hours postoperative), and group B (57 patients) in which warfarin will be started day 5 after caesarean delivery, then maternal complications are compared among these 2 groups.
