Altered Right Ventricular Kinetic Energy Work Density and Viscous Energy Dissipation in Patients with Pulmonary Arterial Hypertension: A Pilot Study Using 4D Flow MRI
Fig 1
(A) Flow pattern of a healthy subject in the right ventricle and the pulmolnary artery. The flow is laminar and is of relatively high velocity. (B) Flow pattern of a PAH patient with severe PA dilation where the vortices form in the PA and the flow velocities are lower.
