Prognostic value of pulmonary vascular resistance estimated by echocardiography in dogs with myxomatous mitral valve disease and pulmonary hypertension.

ABSTRACT:

Background

Progression to combined post- and pre-capillary pulmonary hypertension (PH) provides prognostic information in human patients with post-capillary PH. Pulmonary vascular resistance estimated by echocardiography (PVRecho) is useful for the stratification of dogs with myxomatous mitral valve disease (MMVD) and detectable tricuspid regurgitation.

Objectives

To evaluate the prognostic value of PVRecho in dogs with MMVD.

Animals

Fifty-four dogs with MMVD and detectable tricuspid regurgitation.

Methods

Prospective cohort study. All dogs underwent echocardiography. The PVRecho was calculated based on tricuspid regurgitation and the velocity-time integral of the pulmonary artery flow. To evaluate the influence of echocardiographic variables on cardiac-related
