Abstract
The study evaluated the cardiac functions of dogs infected with Dirofilaria immitis infection, using 2D and M-mode ultrasonography. A total of 15 heartworm positive adult dogs tested using MCT, aged 3.8+2.62 years old, weighed 9.78+4.99kg, with body composition score of 4.73+1.06 were examined. Among the 15 animals only six (40%) have clinical symptoms, animals are then prepared for ultrasonography evaluation.
Adult canine heartworms (HW) were visible as two parallel lines separated by a very thin hypoechoic center located within the right pulmonary artery. Sometimes extending to the main pulmonary artery and right ventricle. HW was visible only in ten (60.67%) dogs with varying worm loads. The results of this study showed that there were alterations in some chamber measurements and functions and right pulmonary artery distensibility index of heartworm positive dogs based on their body weight and the established reference values.
