Evaluation of the diagnostic and prognostic potential of optical coherence tomography (OCT) of the pulmonary arteries during standardised right heart catheterisation in patients with pulmonary hypertension: a cross-sectional single-centre experience.

There were highly significant correlations between WT and WT/DM with the haemodynamic parameters mean pulmonary arterial pressure (mPAP) [Spearman correlation coefficient (r s ) =0.702, P<0.001; r s =0.621, P<0.001], systolic pulmonary arterial pressure (sPAP) (r s =0.668, P<0.001; r s =0.658, P<0.001) and WT and pulmonary vascular resistance (PVR) (r s =0.590, P=0.02).
