MASS THROMBUS OF THE LEFT AURICLE

Abstract

We have used the term mass thrombus to describe a clot that forms in the left auricle during life and by reason of its large size or its peculiar location impedes the flow of blood through the mitral orifice. In this paper we examine the clinical and pathological findings in six cases of mass thrombus with the object of discovering a symptom or sign that would simplify the diagnosis.
