The murmur is usually high-pitched, but oftentimes, not easily heard. This is because the sound is best perceived at the left lower chest, when the patient is either standing or sitting upright.
To better understand this, we must take a closer look at how the heart works.
How does the heart work?
The heart is the center of the circulatory system. It is made up of four chambers. These chambers are connected. Two upper chambers called atria receive blood, while two lower chambers called ventricles, which pump blood.
Four valves open and close to regulate blood flow between the chambers and in and out of the heart. Think of it as a faucet that either opens up to let blood flow spontaneously or closes up to entirely stop the flow.
Tricuspid Valve vs Mitral Valve
For the most part, people have given more consideration to the mitral valve. This is the valve located at the left side of the heart, between the upper and lower left chambers. This primarily because most rheumatic heart diseases are related to abnormalities in the mitral valve.
On the other hand, the tricuspid valve is located between the right atrium and right ventricle. It separates the two right chambers, flapping open to let the blood flow, and immediately closing to prevent blood from flowing backwards.
Tricuspid valve regurgitation basically means that the valve did not close as tightly as it should. This causes blood to flow back into the right atrium when the heart beats.
If a tricuspid regurgitation murmur is not detected immediately, it could lead to a weakened heart.
