Left atrial volume in patients with mitral valve disease was studied with two dimensional echocardiography. The left atrial dimension was derived by planimetry of the left atrial area and, assuming spherical geometry, left atrial volume was calculated. Patients with severe mitral regurgitation had marked systolic expan...
