Summary

In this study, study team aim to i) evaluate the accuracy of 3D IVS curvedness for prediction of RV systolic pressure (RVSP), mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) with RHC; ii) evaluate the usefulness of 3D IVS curvedness for predicting the response to vasodilator challenge with RHC, in patients clinically suspected or known to have primary PH.

Conditions

  • Pulmonary Hypertension

Interventions

OTHER

6MWT

Each patient will also receive 6MWT at cardiovascular rehabilitation and preventive cardiology laboratory. Besides the distance covered in meters or converted measure (such as feet) over 6 minutes, a portable metabolic system is used to measure oxygen uptake during exercise (VO2 testing) for each patient.

OTHER

Cardiovascular Magnetic Resonance Imaging (CMRI)

MRI uses interaction of the magnetic properties of body tissues with strong magnetic fields to create images; for about 1 hour. Several sets of images are needed. No injection of drug or dye will be used for this procedure.
