KARAKTERISTIK ALIRAN DARAH KATUP SEMILUNAR AORTA DINILAI DENGAN PULSED WAVE DOPPLER ECHOCARDIOGRAPHY PADA ANJING KAMPUNG NORMAL (Canis lupus familiaris)
(Blood Flow Characteristics Semilunar Aorta Valve as Assessed by Pulsed Wave Doppler Echocardiography on Normal Mongrel Indonesian Dog)
FITRI ALHAM, DENI NOVIANA
ABSTRACT
The purpose of this study is to determine blood flow characteristics at the aortic valve in normal mongrel Indonesian dog using transthoracic pulsed wave Doppler (PWD) echocardiography. The study was conducted in eight adult dogs consisting of three males and five females with an average age of 3.5 years, and average weight 12.5 kg. Transthoracic PWD echocardiography examination were performed on dogs in a conscious state/unsedated and the animal position in left lateral recumbency. The instrument used is an ultrasound device (Sonoscape SSI-1000) and convex type transducer with small footprint scanner of 3.7-5 MHz frequency. Six parameters of PWD measured were heart rate (HR), peak velocity (Vpeak), velocity time integral (VTI), mean pressure gradient (MPG), pulsatility index (PI), and ratio systole-diastole (S/D). Based on the measurement of six parameters in aorta valves showed that in general the blood flow characteristics values of the female dogs have a higher value when compared with male dog (P>0.05).
