TDI was recorded from the apical four-chamber view. The pulsed-wave Doppler volume was placed on the septal corner of the mitral annulus. Care was taken to ensure that the ultrasound beam was parallel to the direction of the mitral annulus motion. Filters and gains were set to exclude high-frequency signals and to obtain clear tissue signals.

A decrease in e-peak at mitral annulus indicates impaired relaxation.
WebMyxomatous mitral valve disease (MMVD) is the most common chronic heart valve disease, leading to the eccentric hypertrophy. Recently, the leaflet-annulus index (LAI), which focuses on the mitral valve apparatus, has been considered a prognostic factor for human mitral regurgitation (MR); however, it has not been reported in veterinary medicine.
