Summary A mitral valve stenosis was diagnosed in a 2‐year‐old female Bull Terrier by use of two‐dimensional (2‐D) and M‐mode echocardiography, colour‐flow imaging and spectral Doppler examinations. Tissue Doppler Imaging was also performed to assess the segmental radial myocardial motion. The mitral valve stenosis was characterized by a decreased mitral orifice area/left ventricle area ratio (0.14), an increased early diastolic flow velocity (E wave = 1.9 m/s), a prolonged pressure half‐time (106 ms) and a decreased E‐F slope (4.5 cm/s) on pulsed‐wave Doppler examination. This mitral stenosis was associated with an immobile posterior leaflet, as seen on 2‐D and M‐mode echocardiography. Immobility of the posterior mitral leaflet is considered to be a rare finding in humans and, to our knowledge, has not been precisely documented in dogs with mitral valve stenosis.
