Congestive Heart Failure 3D Animation
Congestive Heart Failure 3D Animation
This video in 30 seconds
A one-minute narrated 3D animation explains congestive heart failure. It describes how a prior heart attack, high blood pressure or coronary artery disease can weaken the left ventricle, and how the kidneys retaining water and salt adds congestion and swelling that strain the heart further.
Key points
- The animation identifies the left ventricle as the main pumping chamber
- Prior heart attack, high blood pressure and coronary artery disease are named as causes
- The ventricle enlarging and pumping less effectively is described
- Kidney retention of water and salt is shown causing congestion and swelling
Video Transcript
A one-minute narrated 3D animation explaining congestive heart failure. It describes how a prior heart attack, high blood pressure, or coronary artery disease can weaken the left ventricle, and how the kidneys' response — holding on to water and salt — adds the congestion and swelling that strain the heart further.

A healthy heart, as seen here, beats approximately 60 to 100 times a minute, providing oxygen-rich blood to the rest of the body. The lower left chamber of the heart called the left ventricle is the main pumping chamber. There are many different conditions that can lead to congestive heart failure, including a prior heart attack, high blood pressure, and coronary artery disease. Any of these can prevent the heart from efficiently pumping blood to the rest of the body. As a result, the heart may be faster, and the ventricle may increase in size, becoming an
even less effective pump. When the kidney sends the reduced blood flow, they attempt to compensate by retaining more water and salt. This excess fluid retention often causes congestion in the tissues, and results in swelling and an increased strain on an already weak heart. The progressive effect of the heart failing to properly circulate blood, and congestion due to fluid retention, is known as congestive heart failure.
