An In Vitro Circulatory Loop Model of the Pediatric Right Ventricular Outflow Tract as a Platform for Valve Evaluation

The aim of this study was to develop a robust in vitro system for quantifying flow conditions after various RVOT interventions. The MCL was developed around the ViVitro Pulse Duplicator System with the viscoelastic impedance adapter and ventricle chamber attachments. The 3D-printed RVOT anatomical model and in vitro pulmonary circulatory loop developed in this work provide platform for planning and evaluating surgical interventions in the pediatric population.
