Normal Hearts

Pediatric heart models without any anatomical defects. These are a great resource to compare to any of the congenital heart defects

  • Teenage heart
Explore collection


Defects where the left or right ventricle of the heart is under developed, which affects to blood flow throughout the heart.

  • hypoplastic left heart syndrome (HLHS)
  • HLHS with mitral stenosis and aortic atresia
  • post-glenn repaired HLHS
  • post-Norwood/Sano repaired HLHS

Coming soon!!!

We are working hard preparing more heart models for the library!

All Models

Normal Teenage Heart

This is a model of a normal teenage heart with no defects. It has been coloured to show the two halves of the heart - blue representing the deoxygenated blood and red representing the oxygenated blood. In this model, you can also see the outline of the heart muscle (myocardium) around the ventricles and atria.

Hypoplastic Left Heart Syndrome Norwood/Sano

Hypoplastic Left Heart Syndrome (HLHS) with mitral stenosis and aortic atresia. This patient had a Norwood/Sano operation. This model is coloured to show the deoxygenated (blue) blood and oxygenated (red) blood, which mixes within the heart (indicated as purple). The colouring is meant to explain the physiology and blood flow in a heart after a Norwood/Sono procedure.

HLHS post Glenn Surgery

Hypoplastic Left Heart Syndrome (HLHS) post Glenn, pre-transplant assessment. This coloured bloodpool model shows the mixing of blue deoxygenated blood and red oxygenated blood. Colouring is not based on scientific data. In hypoplastic left heart syndrome, the left ventricle is very small. The Glenn surgery connects the superior vena cava (SVC) to the pulmonary arteries to allow the deoxygenated blood returning from the upper body to bypass the heart and travel to the lungs directly.

Unbalanced AVSD with Fontan Physiology

An unbalanced AVSD (the left ventricle is very small) and Fontan physiology. The Fontan procedure connects the inferior vena cava (IVC) to the right pulmonary artery. Now all the deoxygenated blood from the body bypasses the heart and directly enters the lungs. There is also a small hole between the Fontan conduit and the right atrium which is called a fenestration. The fenestration allows a small amount of the blue deoxygenated blood from the Fontan conduit to enter the heart where the red oxygenated blood is located. This fenestration is meant to relieve some pressure by acting as a "pop-off valve" until the lungs adjust to the new circulation.
