Interrupted aortic arch and VSD (case 3). (A) 3D model of a cardiac specimen with the right ventricle opened at the pathological examination; (B) the same model with the right ventricle closed by CAD, frontal view. The patient underwent a surgical attempt to reconstruct the continuity of the transverse aortic arch by interposing a polytetrafluoroethylene tube (*) between the ascending and descending aorta. At the time of pathological examination incisions were made in the right ventricle and ascending aorta. The latter incision is not closed by CAD. 3D virtual model accurately demonstrates segmental anatomy and the arterial structures. AAo, ascending aorta; LAA, left atrial appendage; LV, left ventricle; PDA, patent arterial duct; PM, papillary muscle of the tricuspid valve PT, pulmonary trunk; RAA, right atrial appendage; RV, right ventricle; SVC, superior vena cava; TV, tricuspid valve leaflet; VSD, ventricular septal defect.
