Radial strain and strain rate assessed by Speckle-Tracking Echocardiography in Turkish Kangal Dogs

Abstract

Objectives: 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.

Materials and Methods: Study Groups of A and B consisted of 3 dogs with dilated cardiomyopathy and 4 dogs with valve disease, respectively. Control Group (C) consisted of 7 healthy dogs. These dogs were presented for cardiac screening at the Veterinary Medical Hospital of Ankara University in Turkey and were analyzed retrospectively

Results: It is revealed that for strain evaluation, Group A was significantly (P<0.05) different from Group C and Group B.

Discussion: According to the literature, this is the first study from Turkey where speckle tracking echocardiography is used to assess the left ventricular function of Turkish Kangal dogs with naturally occurring dilated cardiomyopathy and mitral valve disease. Two-dimensional speckle tracking echocardiography revealed decreased left ventricular myocardial systolic performance in dogs with dilated cardiomyopathy compared with strain levels of healthy dogs and dogs with valve disease.
