Vorticity for the assessment of pulmonary vascular hemodynamics in pulmonary arterial hypertension


Background 4D flow CMR analysis of main pulmonary artery (MPA) flow in pulmonary arterial hypertension (PAH) has demonstrated vortical formations whose existence time correlates with mean pulmonary arterial pressure (MPAP). Vorticity can quantitate the rotation of these vortices and may represent a novel way to assess pulmonary arterial hemodynamics. We… (More)
