Why the study?
Does right ventricular isovolumic relaxation time measured by Tissue Doppler Imaging accurately predict systolic pulmonary artery pressure compared to right heart catheterization in patients with cardiac disease?
Does right ventricular isovolumic relaxation time measured by Tissue Doppler Imaging accurately predict systolic pulmonary artery pressure compared to right heart catheterization in patients with cardiac disease?
Right ventricular isovolumic relaxation time measured by Tissue Doppler Imaging is a highly sensitive and specific non-invasive parameter for predicting systolic pulmonary artery pressure and excluding pulmonary hypertension.

rIVRT' may aid non-invasive SPAP assessment; leaves open whether it can replace catheterization in practice.
