Detecting the presence of pulmonary hypertension (PH) is important especially with unexplained dyspnoea and suspected thromboembolism. Although PH can be detected invasively by right ventricular (RV) catheterisation, accurate non-invasive assessment by echocardiography has many advantages. This however relies on the presence of tricuspid regurgitation (TR). We examined if the presence of PH can be predicted echocardiographically without relying on TR.

The use of the right ventricular diameter and tricuspid annular tissue Doppler velocity parameter to predict the presence of pulmonary hypertension
