Abstract

Background and aim of the study: The left atrial appendage (LAA) is a common source of cardiac thrombus formation associated with systemic embolism in patients with mitral stenosis (MS). Low flow velocities in the LAA are important factors in the development of thrombosis. Whilst oral anticoagulant therapy is used routinely in MS with atrial fibrillation (AF), the characteristics of LAA contractile functions and the protective role of oral anticoagulant treatment in patients with MS in sinus rhythm (SR) are unclear. The study aim was to compare LAA contractile functions in patients with MS who were either in SR or had AF.
