Atrioventricular Valve Endocardiosis (Chronic Heart Valve Inflammation) in Dogs
- Occurrence: common
- Location of illness: Chest
Atrioventricular valve endocardiosis, also known as chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. heart valve inflammation, is a common heart disease in dogs characterized by degenerative changes in the heart valves, particularly the mitral valve. This condition leads to inadequate valve closure, which can lead to heart murmurs and potential heart failure.
The most important facts at a glance
Atrioventricular valve endocardiosis is a heart disease in dogs in which the heart valves thicken and deform, mainly affecting the mitral valve. These changes lead to a backflow of blood into the atria and impair blood flow. The exact causes are unclear, but genetic factors and age play a role. Certain breeds such as Cavalier King Charles Spaniels and Poodles are more commonly affected. Symptoms include reduced resilience, respiratoryRespiratory refers to breathing or the process of breathing.

Causes
The heart valves play a crucial role in regulating blood flow in the heart by ensuring that blood flows in the right direction. In atrioventricular valve endocardiosis, the valves thicken and become deformed, mainly affecting the mitral valve, but can also affect the tricuspid valve. These structural changes lead to a backflow of blood into the atria, which is called regurgitationRegurgitation is the reflux of food or liquid from the stomach into the mouth without Vomiting or strong abdominal muscle contractions. It may be a sign of diseases of the esophagus or other gastrointestinal problems..
The exact causes of these degenerative changes are not yet fully understood, but genetic factors are believed to play a significant role. Certain dog breeds, such as Cavalier King Charles Spaniels, Poodles, Chihuahuas, and Dachshunds, show a higher predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. to this disease. Age is also a significant risk factor, as the likelihood of developing the disease increases in older dogs.
There is also evidence that hormonal and metabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. factors associated with the aging process may contribute to the development of the disease. In addition, environmental influences and dietary habits may play a role, although this has not yet been definitively researched.

The symptoms of atrioventricular valve endocardiosis can vary depending on the severity of the disease. In the early stages, dogs may be asymptomaticAsymptomatic means that there are no recognizable symptoms of a disease. An animal can have a disease or infection without showing visible signs, which can make diagnosis and treatment more difficult. or show only mild clinical signs. A typical first sign is the appearance of a heart murmur, which is detected by the veterinarian during a routine examination.
As the disease progresses, affected dogs often develop symptoms such as cough, which occurs especially at night or during exertion, respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, reduced resilience, and lethargy. These symptoms are due to the backflow caused by inadequate blood flow.
In advanced cases, heart failure may occur, which can manifest as severe breathing problems, abdominalThe term “abdominal” refers to anything that concerns the belly or the abdomen. It is an adjectival expression used to describe the location, symptoms, or conditions that occur in the abdominal area. swelling due to fluid accumulation (ascitesAscites refers to the accumulation of free fluid in the abdominal cavity, which can lead to visible abdominal distension. It can be caused by various diseases, including liver disease, cancer, or heart failure.), and weight gain due to fluid retention. Some dogs may also experience fainting spells or weakness.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of atrioventricular valve endocardiosis usually begins with a thorough clinical examination by a veterinarian. A heart murmur heard with a stethoscopeA stethoscope is a medical instrument used for auscultation, or listening to body sounds, such as heartbeats and lung sounds. It is a fundamental tool in medical diagnostics. is often the first indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. of the disease. However, further investigations are necessary to accurately determine the extent of heart valve disease.
An echocardiogram (heart ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow.) is the best method to assess the structure and function of the heart valves. This imaging technique allows the veterinarian to visualize the valve movements, measure the thickness of the valves, and assess the extent of regurgitationRegurgitation is the reflux of food or liquid from the stomach into the mouth without Vomiting or strong abdominal muscle contractions. It may be a sign of diseases of the esophagus or other gastrointestinal problems.. Chest X-rays can also be helpful in detecting enlargement of the heart and fluid accumulation in the lungs.
In addition, electrocardiograms (ECGs) can be performed to identify cardiac arrhythmiaAn arrhythmia is a heart rhythm disorder in which the heart beats irregularly, either too fast (tachycardia), too slow (bradycardia), or with an irregular pattern. Arrhythmias can be harmless or a sign of serious heart problems., which often occurs in advanced heart valve disease. In some cases, a blood testA blood test is a laboratory procedure in which blood is drawn and analyzed to obtain information about the body's health. It can include various parameters such as blood sugar, blood count, liver and kidney values. may also be performed to rule out other possible causes of the symptoms and to assess the dog’s general health.
Therapy
The treatment of atrioventricular valve endocardiosis aims to alleviate symptoms, slow the progressionProgression refers to the advancement or worsening of a disease over time. It describes an increase in the severity or extent of the disease symptoms. of the disease, and improve the quality of life of the affected dog. In the early stages of the disease, regular monitoring and lifestyle adjustments may be sufficient. These include a balanced diet, controlled exercise, and avoidance of stressful situations.
Diuretics can be used medically to reduce fluid accumulation in the body, and ACE inhibitors to control blood pressure and slow the progressionProgression refers to the advancement or worsening of a disease over time.

It is important that the medication is individually tailored to the dog and regularly checked by the veterinarian.
In severe cases, surgery may be considered, especially if drug therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. is no longer effective. However, heart valve surgery is complex and is only performed in specialized veterinary clinics. This option is usually more expensive and carries its own risks.
Prognosis and follow-up care
The prognosis for dogs with atrioventricular valve endocardiosis depends on several factors, including the extent of valve damage, the presence of symptoms, and the response to treatment. In the early stages of the disease, when there are few or no symptoms, dogs can often live a relatively normal life with regular veterinary monitoring and appropriate care.
However, in more advanced cases, the disease can lead to chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. heart failure, which significantly impairs the quality of life and shortens life expectancy.
