Heart valve disorders can quietly develop over time, often producing subtle symptoms before becoming more serious. Patients throughout Los Angeles and the Inland Empire, including Chino, Inglewood, Sherman Oaks, Lynwood, San Dimas, and Pomona, frequently seek evaluation when experiencing unexplained fatigue, shortness of breath, or chest discomfort. Epic Cardiology often educates patients about valve conditions because early understanding can lead to timely diagnosis and better long-term outcomes. Knowing how the aortic and mitral valves function is the first step in recognizing when something may not be working properly.
Understanding the Role of the Aortic and Mitral Valves
The heart contains four valves that regulate blood flow, but the aortic and mitral valves play particularly vital roles. The mitral valve controls blood flow between the left atrium and left ventricle, while the aortic valve allows oxygen-rich blood to move from the left ventricle into the aorta and out to the body. When these valves open and close properly, blood flows efficiently in one direction.
Valve disorders generally fall into two categories: stenosis and regurgitation. Stenosis occurs when a valve becomes narrowed and restricts blood flow, forcing the heart to work harder. Regurgitation, also called insufficiency, happens when a valve does not close tightly, allowing blood to leak backward. Over time, either condition can strain the heart muscle and lead to complications such as heart enlargement or heart failure if not monitored and treated appropriately.
Common Causes and Risk Factors
Aortic and mitral valve disorders may result from age-related changes, congenital heart defects, rheumatic fever, infections, or degenerative conditions that cause the valve tissue to stiffen or weaken. In older adults, calcium buildup can narrow the aortic valve, leading to aortic stenosis. Mitral valve prolapse, where the valve flaps bulge backward into the atrium, is another common condition that may cause regurgitation.
Risk factors include high blood pressure, coronary artery disease, prior heart attack, and a family history of valve disease. In some cases, symptoms develop gradually and may include shortness of breath during activity, fatigue, palpitations, chest pain, or swelling in the legs. Because these symptoms overlap with other heart conditions, comprehensive testing is essential to determine the exact cause.
Diagnostic Testing and Monitoring
Evaluating suspected valve disease typically begins with a physical examination and imaging studies. An echocardiogram is one of the most important tools for visualizing valve structure and function. It uses ultrasound waves to create detailed images of the heart, allowing providers to assess the severity of stenosis or regurgitation. In certain cases, a transesophageal echocardiogram may be recommended for more detailed imaging, especially when surgical planning is being considered.
Additional tests may include an electrocardiogram to evaluate heart rhythm or an exercise treadmill test to see how symptoms change with exertion. If coronary artery disease is suspected alongside valve disease, a coronary angiogram can assess blood flow in the arteries. For patients who develop rhythm disturbances related to valve abnormalities, monitoring with a Holter monitor or loop recorder may help detect intermittent arrhythmias. In more advanced cases where electrical conduction is affected, pacemaker implantation may be considered.
When to Seek Evaluation
Residents across Los Angeles and the Inland Empire, including those in Chino, Inglewood, Sherman Oaks, Lynwood, San Dimas, and Pomona, should seek medical attention if they experience persistent shortness of breath, chest discomfort, unexplained fatigue, or swelling in the lower extremities. Sudden worsening of symptoms, fainting, or severe chest pain requires immediate care.
Epic Cardiology encourages patients to view heart valve disorders as manageable conditions when detected early. Regular monitoring and appropriate diagnostic testing can help prevent complications and guide decisions about medication, lifestyle adjustments, or potential procedures. By staying informed and attentive to changes in symptoms, individuals throughout Los Angeles and the Inland Empire can take proactive steps to protect their heart health.
