A Kit of Hearts: Life-sized, physical models of real hearts with CHD
Our physical models feel like a real heart and are at the center of our educational tools
Built from real imaging
Derived from echo, CT and MRI, then reviewed and signed off by cardiologists.
Three-dimensional and haptic
Life-sized and tactile. Pick it up, turn it, look inside.
Ready to travel
Cut-foam case, labelled by condition, built for the ward round and the lecture theatre.
Choose from three kits – Most Common, Most Critical, or the Complete set.
Each model is a three-dimensional, haptic reproduction of a real heart, derived from clinical imaging and then simplified with clinicians so the defect reads clearly to someone seeing it for the first time. They are life-sized, soft to the touch, and colour-coded so the anatomy is legible in the hand.
Three kits are available: Most Common and Most Critical, each covering the conditions a team encounters most often, and Complete, which spans the full range of malformations. Every kit ships in a foam-cut protective case, labelled condition by condition, so nothing is lost and the right model is found in seconds.
[ For families ]
Holding the model is the point. Instead of a sketch or a scan, you can see where the hole is, how big the chamber really is, and what the surgeon is describing – and turn it over yourself until it makes sense.
[ For clinical teams ]
Designed for daily use, not display: the case goes to the bedside, into clinic, into a lecture or training session, and back. Clinicians use the models in consent conversations, in family updates, and to teach nurses, trainees and new staff conditions they may rarely see.

[ Most Common ]
10-model kit with 9 CHD models + normal baby heart.
Focused on the congenital heart conditions most frequently encountered in clinical practice. This kit covers 85%* of patients diagnosed with structural congenital heart disease globally. The kit supports everyday communication, teaching, and counselling by providing tangible models that help families understand common cardiac diagnoses and interventions.

KATE HENDERSON
Nurse, Royal Children’s Hospital, Melbourne
“There is only so much a family can take away from a 2D drawing. When they hold the 3D version of their child’s heart in their hands and are spoken through the different parts – a true understanding comes across their faces. It has been incredible to watch.”
GREG KELLY
Intensivist at Sydney Children's Hospital
“I find it incredibly encouraging that we can now develop such beautiful and educational models from modern imaging data, and that these models offer massive advantages over real preserved specimens in terms of ethics, reproducibility and ease of storage and use.”
DARREN HUTCHINSON
Head of Fetal Cardiology at The Royal Women's Hospital
“We currently rely on simple 2D drawings that cannot communicate the complexity of the 3D heart and its multiple possible malformations. These models enhance communication during complex prenatal consultations, helping families visualise cardiac anatomy and potential surgical pathways with greater clarity and confidence”
GORAN
Father
“Seeing the heart and the scale – it helped me understand. I felt calmer after.”
TAMINA
Mother
“Being able to hold the 3D model and see just how small the left ventricle is took my understanding of Lili’s heart condition to a whole new level.”
