Abstract

Echocardiographic morphologic assessment of chordae tendineae- mitral valve system and mitral flow pulsed Doppler studies were carried out in dogs with mitral valve disease. Statistically significant increase in E/A ratio and thickening of anterior mitral valve leaflet was observed as predominant changes during pulse wave Doppler and 2-D echocardiographic studies in the mitral valvular diseased group of dogs when compared to the control group.
