Stopped: COVID-19 has impacted our study recruitment
In this randomized controlled clinical trial, patients with moderate to severe mitral valve stenosis (MS) and atrial fibrillation (AF) will be enrolled into the study.Participants will be divided into two groups based on the anticoagulation regimen type. The intervention group will receive rivaroxaban and the control group will be given warfarin. All patients will be observed closely during a period of one year. Through the follow up, embolic events and hemorrhagic complications will be recorded in both groups. In addition, patients in both group will undergo a baseline magnetic resonance imaging (MRI) and an MRI after one-year follow up, by which the silent embolic events will be compared in both groups.
