Structured PICO

Does magnetic resonance 3D Fourier encoding velocity imaging accurately quantify hemodynamics in patients with primary pulmonary hypertension compared to right heart catheterization?

Population

13 patients with primary pulmonary hypertension (PPH) confirmed by right heart catheterization and 10 volunteers (total n=23).

Intervention

Magnetic resonance (MR) 3D Fourier encoding velocity imaging

Comparator

Right heart catheterization (RHC) and healthy volunteers

Outcome

Pulmonary flow differences (antegrade velocities, acceleration time, arterial distensibility) and agreement between MR and RHC for right cardiac output and stroke volumesurrogate

MR 3D Fourier encoding velocity imaging is a reliable noninvasive method for quantifying right-sided hemodynamics in patients with primary pulmonary hypertension.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

MR metrics may support noninvasive PPH assessment; leaves open RHC replacement due to low absolute agreement.
