2D and color Doppler echocardiography in dogs with CMVI. (A) Mitral valve prolapse, which is characterized by one or both leaflets bent back into the left atrial chamber during systole, occurs commonly in dogs with CMVI. The severity of mitral valve prolapse was significantly correlated with MR severity. (B) The mitral valve lesions associated with CMVI are large and irregular in advanced stage of CMVI. Anterior leaflet of mitral valve is more commonly affected than posterior leaflet in dogs. (C) Color‐flow Doppler imaging in 2D echocardiography revealed severe regurgitant jets from left ventricle to left atrium during systole and is widely used for detection and assessment of MR in dogs with CMVI. (D) The MR can be also detected in color M‐mode echocardiography on the LV short‐axis view. LV, left ventricle; CT, chordae tendineae; AMV, anterior mitral valve; PMV, posterior mitral valve; RV, right ventricle; RA, right atrium.

2D and M‐mode echocardiography in dogs with CMVI. (A) Abnormal excursion (decreased EF slope) and thickening of anterior mitral leaflet can be detected in M‐mode echocardiography. (B) The eccentric hypertrophy, which is characterized by an increase in end‐diastolic left ventricular dimensions (EDV), occurs in dogs with CMVI. (C)–(D) Hemodynamically significant chronic MR can induce volume overload, which subsequently can increase LV and LA volume and can result in LA and LV dilation. The degree of left atrial enlargement that is assessed by the left atrium to aorta (LA/Ao) ratio in 2D and M‐mode echocardiography and is closely correlated with the severity of heart failure.

Pulse and continuous Doppler and tissue Doppler echocardiography in dogs with CMVI. (A) The transmitral flow profile consists of E and A and is affected by the pressure gradient between the LA and LV. Elevated E represents increased LA pressure and a worsening of heart failure. (B) Continuous Doppler echocardiography is useful to detect MR in dogs with CMVI. However, the degree of MR is not correlated with the severity of CMVI. (C) Pulse Doppler echocardiography in pulmonary venous flow is also useful to assess the progression of CMVI. The presence of pulmonary venous flow at atrial systole (PVa) indicates high LA pressure noticed in advanced stage of CMVI. (D) The early mitral inflow velocity to early mitral annular tissue velocity (E:Ea) ratio can be used to assess LV diastolic function. The E:E’ ratio is significantly correlated with left ventricular filling pressures.
