| The left atrium (LA) was evaluated through the bidimensional method (2-D) (short axis) and the relation left atrium:aorta (LA:Ao) in a group of 40 healthy adult dogs between 1.5 and 7 years of age and weights ranging from 3.2 to 38.3kg, and these values were compared to those in the conventional M-mode. Comparing the variable LA and Ao with the two methods and their respective indexes, significant statistical difference was observed (P<0,001), high positive correlation between the weight and LA-2D and LAM, between body surface and LA-2D and LAM. A difference between LA and Ao in both methods and these respective indicators were observed. The association was higly positive between weight and body surface area (BSA) and between M- mode LA (LAM) and 2-D... |
