Relation of left atrial size to function as determined by transesophageal echocardiography.
One hundred thirty-nine patients who underwent transesophageal echocardiographic studies were grouped by their maximal left atrial (LA) volumes, and their stroke volumes, emptying fractions, and fractional shortening were calculated. In large atria, an inverse relation was found between further increases in LA volume and LA function, determined by emptying fractions and fractional shortening.
