Heart problems related to valves, along with their corresponding therapies
Heart valves play a crucial role in regulating blood flow within the heart. Each of the four valves - the tricuspid, pulmonic, mitral, and aortic - connects to a chamber of the heart and ensures that blood flows in the correct direction. However, disorders can develop in these valves, which can have serious consequences for heart health.
A bicuspid aortic valve, for example, is a type of aortic valve with only two leaflets instead of the usual three. This can lead to conditions such as aortic stenosis or aortic regurgitation, where the valve does not function properly.
Ebstein's anomaly, on the other hand, affects the tricuspid valve, causing issues with its closure. This can result in conditions such as tricuspid regurgitation or tricuspid stenosis.
Mitral regurgitation is a disorder that affects the mitral valve, allowing blood to flow the wrong way into the left atrium from the left ventricle. Mitral stenosis, another condition, restricts blood flow from the left atrium to the left ventricle.
Pulmonary valve stenosis causes the pulmonary valve to thicken over time, narrowing its opening and making blood flow more slowly. This can lead to symptoms such as shortness of breath, chest pain, and fatigue.
Heart valve disorders can also be caused by rheumatic fever, an inflammatory condition that can develop after an infection and can lead to heart valve disorders. Additionally, calcification due to aging can lead to aortic stenosis.
Infective endocarditis, an infection of a heart valve, heart lining, or blood vessel, can also cause heart valve disorders. This is particularly a concern for individuals who have already had heart valve surgery or have certain heart conditions.
Treatment for heart valve disorders depends on the specific valve affected, the type of valve disorder (stenosis or regurgitation), and the severity. In mild or asymptomatic cases, regular check-ups may be enough to monitor the valve function. For more severe cases, medications such as diuretics for fluid overload or medications for arrhythmias may be prescribed.
In some cases, surgical repair or replacement of the damaged valve may be necessary. Traditional open-heart surgery is one option, but minimally invasive techniques such as transcatheter aortic valve implantation (TAVI) are also available. These techniques use smaller incisions and catheters, leading to quicker recovery and less pain than open surgery.
For example, aortic insufficiency causes blood to leak back into the heart, leading to volume overload that eventually weakens the heart muscle. Repair or replacement can restore valve function and prevent heart failure progression.
Mediastinal radiation therapy, especially in childhood cancer survivors, may increase the chance of valve disease later in life. It is important for individuals who have undergone this treatment to be monitored closely for signs of heart valve disorders.
In summary, heart valve disorders commonly present with symptoms such as shortness of breath, chest pain, palpitations, fatigue, dizziness or fainting, swelling in the ankles, feet, or abdomen, and a persistent cough. Management ranges from medication and close monitoring to surgical repair or replacement based on disease severity and patient factors. It is essential to seek medical attention if any of these symptoms are experienced to prevent complications and ensure proper treatment.
