Pressure gradient before and after transcatheter pulmonary valve implantation for repaired tetralogy of Fallot: a new 4D flow MRI measurement
Motivation: Estimating pressure gradients due to valvular disease using 4D flow MRI in repaired TOFGoal(s): Identify the location and extent of the pressure gradientApproach: new 4D flow MRI software for pressure gradient measurementResults: In right heart catheter-defined pulmonary hypertension, this software showed a right ventricular outflow tract to pulmonary artery pressure gradient. Impact: Whereas pressure gradients used to require invasive catheterization, our method is a noninvasive test that does not use contrast media. It also has the advantage of being able to locate the site of the pressure gradient.
