Aortic valve insufficiency: how to recognize, treat, and live with this condition

Basics of aortic valve insufficiency

Aortic valve insufficiency is a condition in which the valve does not close completely during systole, leading to the backflow of blood from the aorta into the left ventricle. This can result in increased blood volume in the ventricle, disrupted blood flow, and deteriorated heart function. The main causes of aortic valve insufficiency include rheumatic fever, degenerative changes of the valve, and congenital anomalies. Treatment may involve monitoring, medication therapy, or, in some cases, surgical correction depending on the severity and symptoms of the condition.

Etiology of aortic valve insufficiency

Aortic valve insufficiency can be caused by various factors, including rheumatic valve disease, deformations of the valvular apparatus, aortopathies, congenital structural defects of the valve, infections, and other conditions. Rheumatic valve disease remains one of the main causes of aortic valve insufficiency, while deformations of the valvular apparatus may result from abnormal development or trauma. Understanding the causes of aortic valve insufficiency is crucial for selecting the optimal treatment and management strategy for this condition.

  • Rheumatic valve damage: as a result of rheumatic fever, damage to the aortic valve may occur.
  • Deformations of the valve apparatus: any anomalies or damage to the valve structure can lead to its insufficiency.
  • Congenital valve structure disorders: abnormal development of the aortic valve from birth can be the cause of its defect.
  • Aortopathies: diseases of the aorta, such as aortitis or Marfan aortopathy, can affect the function of the aortic valve.
  • Infections: infectious processes, especially endocarditis, can cause damage to the valve and lead to its insufficiency.

The clinical picture of aortic valve insufficiency

The clinical picture of aortic valve insufficiency may include symptoms related to hemodynamic disturbances, such as fatigue, shortness of breath with physical exertion, palpitations, and increased pulsation in the neck. Patients may also experience dizziness, chest pain, edema, recurrent pneumonia, or acute upper respiratory infections. These signs and symptoms may result from increased loading of the left ventricle and the resulting heart failure due to the regurgitation of blood through the insufficient aortic valve.

  • Fatigue and weakness: patients often complain of general weakness and fatigue, especially with physical exertion.
  • Shortness of breath: shortness of breath, especially with physical activity, is one of the most common symptoms of aortic valve insufficiency.
  • Palpitations: rapid heartbeat or the sensation of heartbeats in the neck may be noticed by some patients.
  • Syncope: instances of loss of consciousness or dizziness may occur due to insufficient blood supply to the brain.
  • Heart enlargement: patients with aortic valve insufficiency may exhibit heart enlargement due to overload.

Approaches of specialists to the treatment of aortic valve insufficiency

The treatment of aortic valve insufficiency depends on various factors, including the severity of the disease, the patient’s symptoms, the presence of complications, and comorbidities. Experts typically approach the choice of treatment method on an individual basis, considering all aspects of the specific clinical situation. Treatment options may include conservative treatment to manage symptoms and reduce the burden on the heart, as well as surgical interventions such as repair or replacement of the aortic valve, depending on the patient’s needs.

Some experts also consider the possibility of minimally invasive procedures or transcatheter interventions, which may be preferred in certain patients. A key aspect of treatment is the aim to improve the patient’s quality of life, reduce the risk of complications, and maintain optimal heart function. Expert opinion is essential for making individualized treatment decisions for aortic valve insufficiency, taking into account optimal outcomes and patient well-being.

Methods for diagnosing aortic valve insufficiency

Various methods are used for the diagnosis of aortic valve insufficiency, including echocardiography, which is the primary tool for assessing the severity and characteristics of valve insufficiency. This method allows for the determination of the volume of backward blood flow through the aortic valve, the sizes of the heart cavities, as well as the evaluation of left ventricular function. Additionally, magnetic resonance angiography, computed tomography, cardiac catheterization, and other techniques may be used for a more detailed identification of the characteristics of aortic valve insufficiency and the development of a treatment strategy.

  • Echo cardiography: The primary diagnostic method that allows assessment of the degree and characteristics of aortic valve insufficiency, the volume of backflow, and heart function.
  • Magnetic resonance angiography: This method provides detailed information about the structure of the valve, the sizes of heart chambers, and the overall condition of the heart.
  • Cardiac computed tomography: Allows visualization of the structure of the valve, aorta, and heart, which aids in the assessment of aortic valve insufficiency.
  • Cardiac catheterization: Used for precise measurement of pressure in the heart and aorta, as well as for evaluating backflow through the valve.
  • Stress echocardiography: A method that allows assessment of the behavior of aortic valve insufficiency under physical load, useful for evaluating the functional state of the heart.

Principles of treating aortic valve insufficiency

Treatment of aortic valve insufficiency may include conservative methods, such as medication therapy to manage symptoms or prevent complications, as well as surgical intervention. Surgical correction may involve repair or replacement of the valve depending on the clinical situation and individual characteristics of the patient. The decision on the treatment of aortic valve insufficiency is made after a thorough assessment of the degree of valve function impairment, the state of heart failure, and the overall clinical status of the patient.

  • Medication therapy: Includes the use of medications to control symptoms, improve heart function, and prevent complications.
  • Surgical intervention: If necessary, repair or replacement of the aortic valve may be performed to restore normal blood flow.
  • Dynamic monitoring: It is important to regularly monitor the condition and dynamics of aortic valve insufficiency through various diagnostic methods.
  • Physical activity: Moderate physical activity is recommended, taking into account individual characteristics and specialist recommendations.
  • Maintaining a healthy lifestyle: Includes healthy eating, giving up bad habits, regular medical check-ups, and following all doctor’s prescriptions.

Measures to prevent aortic valve insufficiency

Prevention of aortic valve insufficiency includes the following aspects: regular monitoring of the cardiovascular system, especially in the presence of risk factors such as rheumatic fever, congenital heart defects, or other pathologies that may lead to deformation or damage to the valves. Controlling blood pressure, maintaining a healthy lifestyle, including regular physical exercise and a balanced diet, also play an important role in the prevention of aortic valve insufficiency. Regular medical examinations and timely consultation with a doctor when experiencing discomfort will help identify any changes in heart function and initiate treatment in a timely manner, which contributes to the prevention of serious cardiovascular diseases.

  • Maintaining a healthy lifestyle, including moderate physical activity and proper nutrition, plays a key role in the prevention of aortic valve insufficiency.
  • Regular monitoring of blood pressure and keeping it at an optimal level contributes to the preservation of heart and vascular health.
  • Avoiding tobacco smoke and minimizing alcohol consumption also reduce the risk of cardiovascular diseases, including aortic valve insufficiency.
  • Regular medical check-ups and examinations allow for the detection of initial symptoms and changes in heart function, which facilitates early diagnosis and prevention of the development of pathologies.
  • Upon identifying risk factors such as rheumatic diseases, it is necessary to follow the doctor’s recommendations for heart disease prevention and systematically undergo prescribed examinations.

Unusual aspects of aortic valve insufficiency

Despite the fact that aortic valve insufficiency is a serious condition and requires medical intervention, patients with mild or moderate valve insufficiency may experience a prolonged asymptomatic period. This is because the heart is able to compensate for small volumes of backward blood flow through the valve. Such an asymptomatic period can mislead patients regarding the seriousness of their condition, and regular monitoring is important for the timely detection and management of aortic valve insufficiency.

In addition, some cases of aortic valve insufficiency may be congenital and manifest in childhood. This requires a specialized approach to treatment and long-term medical monitoring. Understanding these unusual aspects of aortic valve insufficiency allows for improved diagnosis, treatment, and prognosis of this condition.
