Valvular Heart Disease Affects Millions Worldwide
Valvular heart disease (VHD) occurs when one or more of your heart valves don't work properly. Often silent in early stages, VHD can lead to serious complications if left undetected. Understanding the condition is the first step toward prevention.
What is Valvular Heart Disease?
Your heart has four valves that keep blood flowing in the right direction. When these valves are damaged or diseased, it affects your heart's ability to pump blood effectively.
Aortic Valve
Left ventricle → Aorta
Controls blood flow from the heart to the body
Mitral Valve
Left atrium → Left ventricle
Regulates blood between upper and lower left chambers
Tricuspid Valve
Right atrium → Right ventricle
Controls flow between upper and lower right chambers
Pulmonary Valve
Right ventricle → Lungs
Manages blood flow from heart to lungs
Common Types of Valve Problems
Stenosis
Valve becomes narrowed and stiff, restricting blood flow
Regurgitation
Valve doesn't close properly, causing blood to leak backward
Prolapse
Valve flaps bulge or prolapse back into the upper chamber
Why VHD Deserves Attention
Valvular heart disease often develops slowly without obvious symptoms, making early detection critical for better outcomes.

Early Symptoms & Risk Factors
Recognizing early warning signs can lead to timely intervention and better health outcomes.
Common Symptoms
Shortness of Breath
Difficulty breathing during activity or when lying down
Fatigue
Unusual tiredness or weakness, especially with exertion
Heart Palpitations
Irregular heartbeat, fluttering, or racing heart
Dizziness or Fainting
Feeling lightheaded, especially during physical activity
Risk Factors
Age Over 65
Risk increases significantly with advancing age
History of Heart Disease
Previous heart conditions increase valve disease risk
High Blood Pressure
Chronic hypertension puts strain on heart valves
Rheumatic Fever History
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, reduce the need for emergency surgery, and significantly improve quality of life.
