Understanding the Signs and Treatment Options
Heart valve disorders can range from mild conditions requiring minimal intervention to severe problems necessitating immediate medical attention. Knowing how to recognize the signs and symptoms is crucial for seeking proper treatment. Keep reading to learn what to look for, and what to ask your doctor about regarding heart valve disorders.
Common Signs and Symptoms of Heart Valve Disorders
Heart valve problems can manifest through various symptoms. Recognizing these warning signs early can lead to faster diagnosis and more effective treatment outcomes. Below are the most common indicators that a heart valve may not be functioning properly.
Shortness of Breath (Dyspnea)
One of the earliest and most common symptoms of heart valve disorders is shortness of breath, which may occur during physical activity, when lying flat or even at rest in advanced cases. This breathlessness happens because a malfunctioning valve causes blood to back up in the lungs or prevents efficient blood circulation, reducing oxygen delivery throughout the body.
Fatigue and Weakness
Persistent fatigue that doesn't improve with rest often indicates a heart valve problem. When valves don't open or close properly, the heart must work harder to pump the same amount of blood, leading to inefficient circulation and reduced oxygen delivery to muscles and tissues. This inefficiency manifests as general weakness, decreased exercise tolerance and exhaustion even after minimal physical effort.
Heart Palpitations
Heart valve disorders frequently cause noticeable palpitations—sensations of irregular, rapid or forceful heartbeats. These occur because the heart attempts to compensate for the valve dysfunction by beating harder or developing rhythm abnormalities. Patients often describe palpitations as "fluttering," "pounding" or feeling like their heart is "skipping beats."
Heart Murmur
Though not a symptom patients can feel, heart murmurs—unusual sounds detected during a stethoscope examination—often provide the first clue to valve problems. These sounds result from turbulent blood flow through narrowed or leaking valves. Different valve disorders produce distinctive murmurs that trained medical professionals can identify.
Not all murmurs indicate disease; some "innocent" murmurs occur in healthy hearts. However, new or changing murmurs always deserve medical investigation, especially when accompanied by other symptoms.
Swelling in Extremities
Edema—fluid accumulation causing swelling in the ankles, feet and legs—commonly occurs with advancing heart valve problems. When the heart cannot pump efficiently due to valve dysfunction, blood backs up in the veins, forcing fluid into surrounding tissues. This swelling typically worsens throughout the day and improves somewhat after a night's rest.
Chest Pain or Discomfort
Some valve disorders, particularly aortic stenosis, can cause chest pain similar to angina pectoris. This discomfort typically occurs during physical exertion and subsides with rest. The pain results from the heart muscle receiving inadequate oxygen due to the increased workload caused by the valve abnormality.
Treatment Options for Heart Valve Disorders
Treatment approaches for valve disorders vary based on the specific valve affected, disorder severity, symptoms, overall health and other factors. Below are the primary treatment strategies currently available.
Medication Management
While medications cannot repair damaged valves, they play crucial roles in managing symptoms and preventing complications. Common medications include:
Diuretics help reduce fluid buildup and swelling by increasing urine production, relieving symptoms of congestion in the lungs and extremities. These "water pills" provide significant symptom relief but require monitoring for electrolyte imbalances.
Beta-blockers and calcium channel blockers help control heart rate and reduce the heart's workload, improving efficiency despite valve abnormalities. By slowing rapid heart rates, these medications allow more complete heart filling and can reduce symptoms like palpitations and shortness of breath.
ACE inhibitors and ARBs may help control blood pressure and reduce strain on damaged valves while protecting heart function over time. These medications expand blood vessels, making it easier for the heart to pump blood forward despite valve abnormalities.
Surgical Valve Repair
When possible, repairing the native valve offers advantages over replacement. Common repair techniques include:
Annuloplasty reinforces the valve ring with a prosthetic band to improve closure and prevent leakage. This technique frequently resolves mitral regurgitation by restoring proper alignment of valve leaflets.
Commissurotomy separates fused valve leaflets in stenotic valves, improving opening and blood flow. This approach works well for certain mitral stenosis cases, particularly those caused by rheumatic fever.
Valve Replacement Surgery
When repair isn't possible, replacing the damaged valve becomes necessary. Two main types of replacement valves are available:
Mechanical valves offer exceptional durability, often lasting a lifetime without deterioration. However, they require lifelong anticoagulation therapy to prevent blood clots from forming on the valve surface. These valves make an audible clicking sound that some patients find noticeable.
Biological (tissue) valves made from animal tissue (typically porcine or bovine) or human donor tissue don't require long-term anticoagulation but have limited durability, typically lasting 10-15 years before needing replacement. They're often preferred for older patients or those unable to take blood thinners.
