Feasibility of Non-invasive Hemodynamic Assessment by 5D Flow in Congenital Heart Disease

Enrolling by invitation · Not applicable

Conditions studied: Pulmonary Hypertension, Right Ventricular Outflow Tract Dysfunction, Fontan Circulation

In brief

This study evaluates whether new flow parameters of the cardiac magnetic resonance imaging (MRI) allow evaluation of parameters for which usually invasive rigth-left heart catheterization are necessary. Patients who require a right-left heart catheterization will undergo the same day a heart catheterization in the MRI. Parameters obtained by MRI will be compared to the gold-standard, the right-left heart catheterization.
