Reduced and translucent cardiac model with the retinal system

This transparent heart model is slightly smaller than a natural heart. It is ideal for understanding the conduction system and the heart's blood supply from the aorta. The front part of the model is removable and the entire model is supplied on a removable base. 

Anatomically, the following is shown on the model: 

1) The conduction system

2) Coronary arteries and veins

3) The large vessels that carry blood to and from the heart

The four chambers of the heart are also illustrated, but they appear less clear. Smaller anatomical structures are not seen. 

The conduction system is shown in a very educational way, so you can see how the impulses are conducted from the sinus node through other important structures such as the atrioventricular node, the bundle of His and the Purkinje fibers. 

The model shows the major coronary arteries first and foremost. Arteries are shown in red and veins in blue. The right coronary artery (a. coronaria dexter or RCA) runs on the right side of the heart to the back and gives off the posterior interventricular branch, which is also seen. The left coronary artery (a. coronaria sinister) divides into the two major vessels, the anterior interventricular branch (LAD) and the circumflex branch (CX). Most of the venous blood collects in the coronary vein (sinus coronarius), which empties into the right atrium. Smaller veins are also shown. 

The major vessels that carry blood to and from the heart are the aorta (great artery of the body), the superior vena cava (superior vena cava) and the pulmonary trunk (pulmonary artery). The openings to the inferior vena cava (inferior vena cava) and the pulmonary veins (pulmonary veins) are also seen. 

Clinically, the model does not show any pathology (disease-related) but it is perfect for illustrating conduction defects such as atrial fibrillation, AV block and bundle branch block. In addition, this model can be used as a starting point to describe atherosclerosis, blood clots in the coronary arteries, as well as medical treatment or invasive cardiology such as balloon angiography (PCI) and coronary angiography.
