<p><span><span><span>The <a href="https://www.nhlbi.nih.gov/health/heart-valve-diseases/causes" rel="noreferrer">causes</a> of heart valve diseases vary from person to person. You may be born with a heart valve problem, or it may happen because of age or an infection. You may also have a heart valve problem but not experience any <a href="https://www.nhlbi.nih.gov/health/heart-valve-diseases/symptoms" rel="noreferrer">symptoms</a>. Or, your symptoms may develop over time. Extreme tiredness (fatigue) is often the first symptom. You may also feel faint or lose consciousness, have  breathing difficulty or <a href="https://www.nhlbi.nih.gov/health/angina" rel="noreferrer">chest pain</a>, or feel that your heart is skipping a beat, fluttering, pounding, or racing.</span></span></span></p>

<p><span><span><span>To <a href="https://www.nhlbi.nih.gov/health/heart-valve-diseases/diagnosis" rel="noreferrer">diagnose a heart valve disease</a>, your doctor may ask about your symptoms, listen to your heart, or order imaging tests to look at your heart. In newborns, <a href="https://www.nhlbi.nih.gov/health/heart-valve-diseases/diagnosis" rel="noreferrer">screening tests</a> can detect and help diagnose heart valve conditions. </span></span></span></p>

<p><span><span><span>Most heart valve conditions are treatable. <a href="https://www.nhlbi.nih.gov/health/heart-valve-diseases/treatment" rel="noreferrer">Medicine</a> may treat symptoms or prevent the condition from getting worse. Your doctor may also suggest surgery or another procedure to repair or replace a faulty heart valve. If not diagnosed and treated promptly, heart valve problems can lead to <a href="https://www.nhlbi.nih.gov/health/arrhythmias" rel="noreferrer">arrhythmia</a>, infection, <a href="https://www.nhlbi.nih.gov/health/pulmonary-hypertension" rel="noreferrer">high blood pressure in the lungs</a>, <a href="https://www.nhlbi.nih.gov/health/heart-failure" rel="noreferrer">heart failure</a>, or <a href="https://www.nhlbi.nih.gov/health/cardiac-arrest" rel="noreferrer">cardiac arrest</a>. </span></span></span></p></div>
