Abstract

The study was conducted to record the various clinical, electrocardiographic, radiographic and echocardiographic changes in dogs with Pulmonary Hypertension (PH) due to mitral valve disease (MVD). Among the MVD, dogs 15.5 per cent, 8.7 per cent and 4.8 per cent had mild PH, moderate PH and severe PH respectively. A highly significant increase in tricuspid regurgitation velocity (>2.5 mm/Hg), tricuspid regurgitation peak gradient (>25 mm Hg), was recorded in dogs with mild, moderate and severe PH due to MVD when compared to their disease control. A highly significant increase in of MPA/Ao (>0.8)  ratio was recorded in dogs with various degree of PH (mild, moderate and severe) when compared with dogs without PH. According to the severity tricuspid regurgitation flow pattern in the right atrium during systole was recorded in all these dogs. In dogs with MVD, moderate to severe PH worsens outcome.
