ADA-307D Reviewed: A 3X Heart With Five Parts and One Published Price

Short answer: ADA-307D is a middle-sized heart model, enlarged three times and dissecting into five parts. The product page states it shows the external features and internal structures of the heart and the relation between the heart and the large blood vessels, quotes US $26.22, and states ISO and CE certification. It does not publish dimensions, weight or a part-by-part list, and it does not claim any pathology.

Key takeaways

• 3X is the practical middle: large enough for a seminar room, small enough to store in a drawer.
• Five parts is enough to open the chambers and the great-vessel roots without turning the model into a puzzle.
• US $26.22 is published, which is unusual in this catalogue and useful for budget lines.
• Normal anatomy only — no valve disease, no congenital defect, no conduction system claimed.
• Heart anatomy teaching is being rebuilt around visual tools, and a physical model is one input among several [1][2][3].

What five parts can and cannot do

Teaching objective	Supported by ADA-307D	Not supported
Name the four chambers and their walls	Yes — the model opens into five pieces	Myocardial thickness comparison is not quantified on the page
Trace aorta and pulmonary trunk from the heart	Yes — great-vessel relation is an explicit claim	No distal arch branches claimed
Show valve position	Implied by internal structure access	No separate valve leaflets listed
Explain a murmur or a defect	No	Pathology is out of scope for this SKU
Demonstrate the conduction system	No	Requires an innervation or conduction model
Run an auscultation drill	No	Requires an electronic or auscultation simulator

Why 3X rather than 1X or 4X

Scale is a compromise between visibility and storage. A life-size heart is anatomically honest but hard to read from the back of a room; a 4X model is dramatic but dominates a desk and is awkward to pass around. Three times enlargement sits in the middle: a student at two metres can still see the chamber walls, and the model fits in a standard cabinet.

The education literature is more interested in how the model is used than in its scale. A 2025 study in BMC Medical Education measured the learning curve of graded, progressive image-model teaching in echocardiography — the finding being that staged exposure shortens the curve [1]. A 2026 paper in Journal of Cardiothoracic Surgery tested hand-drawn schematic diagrams in congenital heart disease teaching, which is the cheapest possible visual aid and still beat passive slides [2]. A third paper, in Advances in Physiology Education, described freely accessible cardiac physiology and anatomy teaching tools [3]. Taken together, they argue for one physical reference plus structured drawing — not for a bigger model.

Where it fits in a course

Session	Use of ADA-307D	Time
Anatomy introduction	Open all five parts, name chambers, rebuild without a diagram.	20 min
Great vessels	Trace aorta and pulmonary trunk, then draw the relation from memory.	15 min
Clinical correlation	Point to where a valve sits and explain what a stenotic valve would change — on the model, not on a slide.	15 min
Assessment	Five parts shuffled; student reassembles and names each in 60 seconds.	10 min

What the product page does not publish

Not stated on the page	Why it matters
Dimensions and weight	Needed to judge shelf space and freight.
Part-by-part breakdown	Confirm the five pieces match your teaching sequence.
Material	Affects cleaning and lifespan in a shared lab.
Stand or base	Decides whether it can be displayed upright.
Volume price	US $26.22 is a unit price; class sets need a band.

FAQ

Q1. What is ADA-307D?
A middle heart model, enlarged three times and dissecting into five parts, showing external features, internal structures and the relation to the large blood vessels.

Q2. How much does it cost?
The product page publishes US $26.22 per unit. Volume pricing is not published.

Q3. Does it show pathology?
No. The page describes normal anatomy only.

Q4. Is it suitable for cardiology residents?
As a spatial reference, yes. For echocardiography or auscultation training, a dedicated simulator is required.

Q5. What are the dimensions?
They are not published. Ask before you plan storage or freight.

Q6. How do I order?
Email chinoncpr@adaanatomy.com with model ADA-307D, quantity and delivery city.
