INTRODUCTION
A 9 years old female mix breed (Dachshund X Pomeranian) dog weighed 9 kg was having difficulty to breath, exercise intolerance, anorexia, vomit, and a decrease in body weight. Then the dog was referred to Animal Teaching Hospital, Faculty of Veterinary Medicine - Bogor Agricultural University to get an echocardiography examination.
OBJECTIVES
This study aimed to investigate the cause of the clinical signs and the possibility of heart problems through an echocardiography examination.
METHODS
The anamnesis was recorded, and the physical examination was done to evaluate further health problems, and an echocardiography was performed as supporting diagnostic procedure.
RESULTS
Physical examination has shown that the dog was lethargic, arrhythmic, murmur heart sounds (on the
right side), and also exhibit an abdominal pain. Further examination, the Bright-Mode (B-Mode), Motion-Mode (M-Mode), and Color Flow Doppler-Mode (CFD-
Mode) echocardiography, were then performed. The echocardiography showed that the tricuspid valve was thickening and was not perfectly closing which caused a turbulence of blood flow. Moreover, there was also an enlargement of the left atrium even though the value of fractional shortening (FS) and ejection fraction (EF) were still in normal limit.
CONCLUSIONS
From these results, the diagnose for the dog was concluded as tricuspid valve dysplasia (TVD) and mild left atrial enlargement. Despite the rare number of TVD case in animals, but an immediate echocardiography examination should be performed in a patient with impaired cardiac function, to detect and identify potential heart problems as quickly as possible.

INTRODUCTION
In cats, diseases involving caudal area such as at lower urinary tract, perineum or hind limb can cause lymphadenopathy at intra-abdominal caudal abdomen. Due to less sensitivity of radiographs and lymph
node location that may cause difficulty to detect
by ultrasonogram, computed tomography (CT) can provide much more information. However, there has no information of normal appearance of feline caudal abdominal lymph node.
OBJECTIVES
Therefore, the aim of this study was to investigate the appearance of caudal abdominal lymph nodes in healthy cats.
METHODS
Abdominal pre- and post-contrast enhanced CT images were performed in 15 healthy cats, which divided into
3 groups; kitten, mature and senile cats. Then, the appearance, location and size (width, length and height) derived from multiplanar reconstruction were evaluated.
RESULTS
Among 15 cats, internal iliac lymph node was detected only in 5 cats with average size of 2.4 x 4.2 x 2.3 mm.
In contrast, medial iliac and sacral lymph nodes were distinct on post-contrast CT images with average size of 4.1 x 11.8 x 3.2 and 3.5 x 6.9 x 3.6 mm, respectively. In addition, age of cats has effect on lymph node size. The result showed that kitten has significantly larger size of medial iliac lymph node than other groups (P = 0.0013).
CONCLUSIONS
In summary, in healthy cats, internal iliac lymph node
is hard to be detected and age of the cat would effect to the size of lymph nodes. This information would be applied as reference values prior detecting lymph node abnormalities in clinical practice.
