Summary

This study explores whether a cardiac MRI can safely and effectively gather the same heart pressure and flow measurements normally obtained through right heart catheterization, a more invasive procedure. Researchers will attempt to perform the catheterization inside the MRI machine using a special probe visible on the scan. If it works, patients with conditions like pulmonary hypertension or cardiomyopathy could avoid a separate invasive procedure.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Cardiac MRI with Swan Ganz probe navigation using gadolinium
What this could lead to
If successful, this approach could replace invasive right heart catheterization with a safer, MRI-based procedure for diagnosing certain heart conditions.
What could go wrong
This is a small feasibility study with only 35 participants, so results may not apply broadly. The procedure still requires a catheter and contrast agent, carrying some risk.
