title: Effect of isolated left atrial enlargement on mitral annular size and valve competence.
abstract: Effect of isolated left atrial enlargement on mitral annular size and valve competence was evaluated in 62 patients with normal left ventricular size and function and intrinsically normal mitral leaflets. Echocardiographic data showed that isolated left atrial enlargement could cause enlargement of the mitral annulus and cause mitral regurgitation.
