Echocardiography as a definitive diagnostic tool for dilated cardiomyopathy in dogs
2012
Singh, A.P. | Singh, N. | Mahajan, S.K.
Seven clinical cases of dogs of different breeds and ages, showing anorexia, exercise intolerance, lethargy and weight loss, were subjected to thorough physical, haematological, serum biochemical, radiographic, and 2-D mode, M-mode and Doppler echocardiographic examinations. In late dilated cardiomyopathy (DCM) (n=5), both systolic and diastolic left ventricular dimension, EPSS and LA/Ao ratio were increased with reduced fractional shortening (FS). Mild mitral regurgitation was observed in three cases of late DCM. In early DCM (n=2) there was normal diastolic dimension (LVIDd) but increased systolic left ventricular dimension (LVIDs) and hence reduced FS was found.
