The aim of the present study was to verify the validity of two-dimensional echocardiographic (2DE) measurement technique in dogs with left atrial enlargement. Thirty-one dogs with clinically and echocardiographically proven cardiac diseases were randomly selected. The left atrial right-to-left diameter (Lar−l) and the diameter of the left atrium just above the mitral annulus (Laama) as well as the ratio of left atrial to aortic diameter (La/Ao) were measured by 2DE. The Lar−l/ Laama ratio was independent of body weight (R2= 0.0006) and age (R2 = 0.0012), respectively. A significant linear relationship was found between Laama and La/Ao (the ratio that expresses the severity of atrial enlargement): Laama=1.2238 La/Ao + 1.1608 (R2 = 021; P < 0.01). There was also a positive linear relationship between Lar−l and La/Ao :Lar−l = 1.6876 La/Ao + 1.2648 (R2 = 0.27; P < 0.005). In our dogs with cardiac disease, the Lar−l/Laama ratio showed no significant relation to the La/Ao index (R2 = 0.028). Thus, Lar−l/Laama proved to be independent of the severity of atrial enlargement. Based on the strong relationship stated in the equation between Laama and Lar−l [Lar−l/Laama = 1.31159 (95% confidence interval)], Laama can also be used for the assessment of left atrial size even in dogs with cardiac disease.
