The diagnosis of pulmonary hypertension (PH) in dogs and cats can be very challenging. In humans, the gold standard in the diagnosis of PH is to perform right heart catheterization (RHC). However, in dogs and cats, the RHC is limited to research and cannot be practically performed in a clinic.  Echocardiography can then be a useful diagnostic tool for PH in dogs and cats. In this session, echocardiographic views and Doppler measurements used in the diagnosis of PH will be discussed with some case-sharing experiences.
