In this study, it was aimed to evaluate EF and FS parameters at different stages of canine visceral leishmaniasis to benefit in diagnosis and treatment monitoring. A total of 35 dogs, 28 of which were infected with L. infantum and 7 of which were healthy, constituted the material of study. VL diagnosis was confirmed with test kit positivity with fast ELISA on blood samples. VL dogs eligible for inclusion into study were evaluated in 4 different groups (n = 7, each group), according to "LeishVet Working Group". ECHO, studies were performed on the right parasternal short axisand EF and FS parameters were detected. In control group, EF values (%) was found between 48 and 74, FS(%) value between 24 and 38. EF value was found between 59 and 74,FS valuewas between 31 and 42 in group I. EF value was found between 58 and 93, FS value was between 29 and 63 in group II. EF value was foundbetween 35.3 and 93.8, FS value wasbetween 16.4 and 50 in group III. EF value was between 52 and 82, FS value was between 27 and 50 in group IV. As a result, when we considered the LWG, it can be said that echocardiographic evaluation [reduction in FS, EF (systolic dysfunction)] should be performed into account in CVL dogs. It may be beneficial to focus on cardiac changes contributing to the intravital diagnosis in CVL dogs and to apply the necessary additional treatment protocols.
