<p>Aim: Patient-specific fluid dynamic simulation of pulmonary arteries can be a valuable tool in preprocedural</p>
<p>planning. Materials & methods: For three patients, soft, deformable models of the pulmonary</p>
<p>arteries were 3D printed from cardiac magnetic resonance data. In vitro hemodynamics were replicated</p>
<p>using a gear flow pump, 40% glycerol solution and a physical Windkessel module. The pulmonary</p>
<p>pressures were compared with patient cardiac catheterization pressure. Results: The pulmonary artery</p>
<p>pressures and flow volumes had an adequate goodness of fit except for pulmonary pressures in patient 2.</p>
<p>Conclusion: Cardiac magnetic resonance angiogram and flow volume data can be leveraged to generate</p>
<p>a patient-specific 3D model and reproduce in vivo hemodynamics by means of in vitro simulation.</p>
