Abstract

The study was carried out to assess the echocardiographic parameters in dogs with mitral valve insufficiency. Dogs presented to University Veterinary Hospital, Kokkalai and Teaching Veterinary Clinical Complex, Mannuthy with cardiac ailments were screened and eighteen dogs with confirmed mitral valve insufficiency were selected for the study. B -mode, M –mode, colour flow and pulsed wave Doppler examinations were done and compared with that of apparently healthy animals. The left atrium to aorta ratio, ejection fraction, fractional shortening and E point to septal separation values of diseased animals were 1.96±0.14, 59.33±3.60 per cent, 31.83±2.51 per cent and 5.36±0.50 mm respectively.
