Evaluation of left atrium in two-dimensional and M-mode echocardiography in Brazilian boxer dogs
نویسنده
چکیده
The Boxer dogs have high predisposition to show dilated cardiomyopathy (DC). Consequently the evaluation of the left atrium size is important to the assessment of the severity of this disease. In the present study, the aortic root (AO) and left atrium (LA) dimensions were evaluated using two-dimensional (2D) and M mode (M) echocardiography in 36 healthy Boxer dogs. There were used 18 males and 18 females, ranging from 1.5 to 6 years old. A statistically significant difference between the sexes was observed for AO-M, AO-2D, LA-M and LA-2D. A linear regression with body surface area was obtained for AO-M, AO-2D, LA-M and LA-2D. The LA/AO-2D ratio was 1.17 ± 0.11 (n=36) and the LA/AO-M ratio was 1.10 ± 0.11(n=36). The ratios evaluated in twodimensional and M mode also didn’t differ between sexes in healthy Boxer dogs. Key-words: Dogs, Boxer, echocardiography, Left atrium.

Breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. Labrador Retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. So, the present study was aimed to determine the M-mode...

Sixty clinically normal German shepherd dogs, 31 males and 29 females, ranging in age from 1 and 5 years and with a body weight ranging from 22 to 37.2 kg, were examined by the two-dimensional mode, M-mode, and Doppler echocardiography. In Doppler mode, the mitral valve flows were obtained, where the aim was to determine the velocity peaks and ratios of the E and A waves and the mitral E wave d...

The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...
