3D Heart Animation: Cardiology and Human Heart Animation

As a proven and innovative medical animator, Elara has a proud tradition of taking complex anatomical processes and turning them into informative, educational, and realistic 3D animations.

One of our many areas of anatomical expertise is 3D human heart animation. Although many people have a general knowledge of how the heart works and functions, few people outside of physicians, researchers, and clinicians grasp how complex an operation of the heart is.

Elara is frequently tasked with explaining how medical devices, drugs, and other treatment modalities work in conjunction with the heart. These complex physiological and interventional cardiovascular mechanisms can be simplified, illustrated, and better explained through the use of refined, robust, and visually captivating heart anatomy animations. 3D animation is an essential tool for any company in explaining complex science and driving the sales process.

We’ve provided just a few of our samples below for you to see the variety of styles and techniques we employ when creating our work. Because while a heart is always a heart, each one is truly unique.

How The Heart Works

The heart is a fascinating organ. In this scientifically accurate 3D human heart animation, Elara explains the basics of how it functions and illustrates how the electrical impulses within the heart create a normal heart rhythm. The heart has two chambers (the atrium and ventricle) that work together to provide the body with the oxygen it needs to live. Oxygen-depleted blood from the body flows through the chambers’ valves to the heart where it is pumped to the lungs. The oxygen-rich blood then returns to the heart and is subsequently pumped back out to the body. This cycle repeats approximately 60-100 times per minute.

Atrial Fibrillation

Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of stroke, heart failure and other heart-related complications. During atrial fibrillation, the heart’s two upper chambers (the atria) beat chaotically and irregularly – out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness.

Ventricular Tachycardia

is a heart rhythm disorder (arrhythmia) caused by abnormal electrical signals in the lower chambers of the heart (ventricles). Abnormal electrical signals in the ventricles cause the heart to beat faster than normal, usually 100 or more beats a minute, out of sync with the upper chambers. In some cases, ventricular tachycardia can cause your heart to stop.

Device for Valve Replacement

This detailed interactive video was produced to educate physicians and surgeons on the process and implementation device by the name of Acurate TA. This minimally-invasive transcatheter aortic valve implantation (TAVI) device functions as a replacement valve to a damaged left ventricle in the heart. Cracking ones chest is no longer necessary when having this type of procedure.


are called cardiac muscle cells. These cells contain specialized organelles such as myofibrils, mitochondria, the sarcoplasmic reticulum for storage and release of calcium and the sarcolemma which is a membrane that encloses each muscle cell. Cardiomyocytes are very flexible as they shorten and lengthen to perform the mechanical function of a beating heart. They are connected by cellular bridges which allow the heart muscle to act as a single coordinated unit.

Photos or 3D Models?

Do these AED (automated external defibrillator) shots look like photographs? Products can look like photographs but are in fact Elara-built, custom 3D models! Check it out here with the Powerheart G5 Animation.

Cardiac Stress Test

Imagine completing this test on patients without using any wires. That’s what Cardiac Science asked Elara to show in this product feature of the Quinton 9550 Stress Testing System. A cardiac stress test is a cardiological test that measures a heart’s ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by drug stimulation. These tests compare the coronary circulation while the patient is at rest with the same patient’s circulation during maximum physical exertion, showing any abnormal blood flow to the myocardium. The results can be interpreted as a reflection on the general physical condition.
