Lesson

For heart sounds listen to the synthetic sound while reviewing this lesson.

This is an example of severe tricuspid regurgitation which is caused by degeneration of the tricuspid valve leaflets.

The first heart sound is normal. The second heart sound is unsplit.

There is a loud, rectangular, pansystolic murmur.

There is a brief, rumbling, diamond-shaped diastolic murmur.

In the anatomy tab you can see the enlarged right atrium and right ventricle.

You can see the turbulent blood flow from the right ventricle into the right atrium. This is the systolic murmur.

You can see the brief turbulent blood flow from the right atrium to the right ventricle in diastole. This is caused by too much blood in the right atrium which forces blood back into the ventricle during diastole producing the flow rumble.

To differentiate tricuspid regurgitation from mitral regurgitation, the maximum intensity of the tricuspid murmur is heard at the left lower sternal border. In addition, the murmur intensity increases with inspiration.

The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis.


Listening Tips

A summary of the key aspects of this heart or lung sound.
Systole: Loud, pan-systolic murmur, louder during inspiration.
Diastole: Brief, rumbling diamond shaped murmur may follow pan-systolic murmur in some cases.

Auscultation Method

maneuver
The recommended patient position is supine
torso
For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is tricuspid

If you wish to review a complete mobile concerning Tricuspid Regurgitation - Severe Auscultation Reference and related heart sounds, the modules(s) listed below may be useful. Each lesson includes text that explains the auscultatory sound and its clinical significance. The lesson also includes an audio track for playback. A waveform provides a great way to visualize the sounds. Finally, we also include an animation video. For heart sounds, the video illustrates heart muscle and valve movements along with blood flow. For lung sounds, the primary source of the sounds can be seen. Each module also includes a quiz.
