COMPARATIVE ECHOCARDIOGRAPHIC EXAMINATION OF DOGS WITH MYXOMATOUS MITRAL VALVE DISEASE DEPENDING ON THE PRESENCE OR ABSENCE OF PULMONARY HYPERTENSION

Abstract

We found a lack of significant differences in the echocardiographic sizes LA/Ao, LVID-d/Aow and LVID-s/Aow in the examined dogs with myxomatous mitral valve disease (MMVD) after their division depending on the presence or absence of pulmonary hypertension. For the same echocardiographic sizes, we found a high degree of correlation with Mitral Valve E (m/sec). This shows that the echocardiographic M-mode sizes and Doppler measured speed Mitral Valve E rate, which depend on the left atrial pressure in dogs with MMVD prone to development of pulmonary hypertension, may be similar to the same parameters in dogs with MMVD without a tendency to develop pulmonary hypertension.
