Abstract
The association of auricular dilatation with mitral stenosis was well appreciated by clinicians a century ago.1It has long been recognized that in the presence of definite obstruction to the free flow of blood through the mitral orifice the first of the cardiac chambers to be noticeably affected by the altered relations of intracardiac pressure is the left auricle, which increases in size, largely the result of dilatation. This enlargement is often accompanied by an actual hypertrophy of the muscle fibers and an increase in the thickness of the auricular wall. Later the right ventricle and right auricle may be affected in a similar manner. More recently, the profound effect that mitral regurgitation alone, in the absence of stenosis, may at times exert in a similar direction has attracted considerable attention and is well shown in the unusual case recorded by Adam2of a traumatic perforation of the
