Yet very few large trials or registries have been conducted in this population. The INVICTUS program of research in RHD consists of a randomized-controlled trial (RCT) of 4500 patients comparing rivaroxaban with vitamin K antagonists (VKA) in patients with RHD and atrial fibrillation (AF), a registry of 17,000 patients to document the contemporary clinical course of patients with RHD, including a focused sub-study on pregnant women with RHD within the registry. This paper describes the rationale, design, organization and baseline characteristics of the RCT and a summary of the design of the registry and its sub-study. Patients with RHD and AF are considered to be at high risk of embolic strokes, and oral anticoagulation with VKAs is recommended for stroke prevention. But the quality of anticoagulation with VKA is poor in developing countries. A drug which does not require mon clinical course of pregnant women with RHD. Conclusion INVICTUS is the largest program of clinical research focused on a neglected cardiovascular disease and will provide new information on the clinical course of patients with RHD, and approaches to anticoagulation in those with concomitant AF.Cardiogenic shock (CS) complicating acute myocardial infarction (MI) is associated with high mortality. In the absence of data to support coronary revascularization beyond the infarct artery and selection of circulatory support devices or medications, clinical practice may vary substantially. Methods We distributed a survey to interventional cardiologists and cardiothoracic surgeons through relevant professional societies to determine contemporary coronary revascularization and circulatory support strategies for MI with CS and multi-vessel coronary artery disease (CAD). Results A total of 143 participants completed the su
