Mitral valve disease and dilated cardiomyopathy are common acquired cardiac diseases in dogs. Standard echocardiography is commonly used on dogs to non-invasively evaluate myocardial function. The aim of this prospective study was to provide results about variabilities of peak systolic radial strain and strain rate at the level of the papillary muscles using two-dimensional speckle tracking echocardiography in a population of healthy and dogs with cardiologic disorders. Study Groups of A and B consisted of 3 dogs with dilated cardiomyopathy and 4 dogswith valve disease, respectively. Control Group (C) consisted of 7 healthy dogs. These dogs were presented forcardiac screening at the Veterinary Medical Hospital of Ankara University in Turkey and were analyzedretrospectively. It is revealed that for strain evaluation, Group A was significantly (P<0.05) different from Group C andGroup B. According to the literature, this is the first study from Turkey where speckle trackingechocardiography is used to assess the left ventricular function of Turkish Kangal dogs with naturally occurringdilated cardiomyopathy and mitral valve disease. Two-dimensional speckle tracking echocardiography revealeddecreased left ventricular myocardial systolic performance in dogs with dilated cardiomyopathy compared withstrain levels of healthy dogs and dogs with valve disease.
