A 3D Printed Model of Coronary Arteries to Investigate the Correlation Between Congenital Coronary Artery Disease and Cardiac Arrest in an Athlete

A 65-years old athlete referred to Fondazione IRCCS Policlinico San Matteo after cardiac arrest, presenting with a rare right coronary anomaly (right coronary artery ostium atresia) and no other causes of sudden cardiac death. A 3D Virtual model has been reconstructed from CT scan through image segmentation techniques. In CT imaging, the use of contrast medium highlights the blood flowing inside vessels, while their wall remains mostly invisible. To correctly resembles the morphological properties of coronaries, their actual size has been restored computing the vessels, wall relying on the correlation between vessels’ lumen diameter and their wall thickness. The model has been 3D printed in rigid photopolymeric resin exploiting Material Jetting technology. The model clearly shows the well extended circumflex artery into the right atrioventricular groove, till almost reaching the right coronary sinus.  It has been useful to discuss the eventual appropriateness of considering congenital right coronary artery atresia in the differential diagnosis after cardiac arrest.
