This 2-times life size heart model is based on CT scan data of a healthy, adult male and is anatomically correct inside and out. Reproduced sections: (external & luminal surfaces) right atrium, left atrium / right ventricle, left ventricle / aorta /superior & inferior vena cava / pulmonary vein / coronary artery, veins (luminal) mitral valve, tricuspid valve, aortic valve, pulmonary valve / papillary muscle / coronary sinus. The model is pliable which allows seeing all internal structures. For easy examination a scalpel can be used on the model for opening requested areas.Uses of the model:- A simulator for practice in coronary artery bypass grafting or other surgery- A catheterization simulator (Coronary arteries are hollow)- Educational model for learning surgery skills- Stent placement
