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

Single Ventricle

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
  • Fenestrated Fontan

Arch Anomaly

A type of congenital heart condition that involves the malformation of the aortic arch.

Tetralogy of Fallot

A condition that is a combination of four congenital heart defects. These four defects include: a ventricular septal defect, pulmonary stenosis, a misplaced aorta, and a thickened right ventricular wall.

  • Pulmonary Atresia with VSD and MAPCAs

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.

Fenestrated Fontan Physiology

This is a model of a patient with an unbalanced atrioventricular septal defect (AVSD) with a hypoplastic left ventricle who underwent a Fontan procedure as the final stage of the surgical palliation. This is a myocardial model, meaning that you are seeing the muscle of the heart rather than the blood inside the heart. This model has been coloured to demonstrate the presumed oxygen saturations within the different chambers and blood vessels of the heart in the setting of a Fontan fenestration. You can see that there is a small amount of deoxygenated (blue) blood that is able to travel from the Fontan conduit into the right atrium through the Fontan fenestration.

Right Aortic Arch with Aberrant Left Subclavian Artery

This model demonstrates the anatomy of a right aortic arch with aberrant left subclavian artery leading to a vascular ring, which can cause airway and esophageal compression. In this model, the right sided heart structures are depicted in blue, the left sided heart structures in red, the airway in white, and the esophagus in yellow.

Pulmonary Atresia with VSD and MAPCAs

This is a 3D model from a neonate with pulmonary atresia, ventricular septal defect (VSD), and major aortopulmonary collateral arteries (MAPCAs). This patient has 3 MAPCAs which are seen as the abnormal vessels arising from the aorta to supply the lungs. In this patient these vessels have areas of narrowing (stenosis). In this type of congenital heart disease, the patient is born without a pulmonary valve leaving no connection between the heart and the pulmonary arteries. The MAPCAs are formed by the body to supply blood to the lungs. The VSD allows blood to mix between the right and left ventricle.
