Understanding heart valve disease
Valvular heart disease affects millions worldwide. Most never hear it coming.
VHD occurs when one or more of the heart's four valves fail. Often silent in early stages, it can become serious if left undetected.
Four valves keep the blood moving in one direction.
Your heart has four valves that keep blood flowing the right way. When they are damaged or diseased, the heart has to work harder to pump blood effectively.
Aortic Valve
Left ventricle to aorta
Controls blood flow from the heart to the body.
Mitral Valve
Left atrium to left ventricle
Regulates blood between the upper and lower left chambers.
Tricuspid Valve
Right atrium to right ventricle
Controls flow between the upper and lower right chambers.
Pulmonary Valve
Right ventricle to lungs
Manages blood flow from the heart to the lungs.
Three ways a valve can fail.
Each failure mode changes the sound of the heartbeat. That change is what the analyzer listens for.
Stenosis
The valve narrows and stiffens, restricting blood flow.
Regurgitation
The valve does not close fully, so blood leaks backward.
Prolapse
Valve flaps bulge back into the upper chamber.
The silent numbers.
VHD often develops slowly without obvious symptoms, which is why early detection matters.

Know the signs.
Recognizing early warning signs can lead to timely intervention and better health outcomes.
Common symptoms
- Shortness of breath during activity or when lying down
- Unusual tiredness or weakness, especially with exertion
- Irregular heartbeat, fluttering, or racing heart
- Feeling lightheaded, especially during physical activity
Risk factors
- Risk increases significantly with advancing age
- Previous heart conditions raise valve disease risk
- Chronic hypertension puts strain on heart valves
- Past infections can cause lasting valve damage
Why early detection matters.
When VHD is caught early, patients have more treatment options and better outcomes. Early intervention can prevent heart failure and improve quality of life.
- Higher survival rates with early treatment
- More treatment options available
- Lower risk of complications
- Better quality of life outcomes
A simple exam can change the outcome.
If you experience symptoms or have risk factors, consult your healthcare provider. A heart sound examination could catch it early.
