Canine Tricuspid Valve Dysplasia (TVD) is a congenital heart defect that affects the heart’s tricuspid valve, which is located between the right atrium and right ventricle. The condition can cause a variety of signs and symptoms in affected dogs, depending on the severity of their disease.
TVD is typically diagnosed through a combination of physical examination, chest X-rays, echocardiography (heart ultrasound), and electrocardiogram (ECG ).
The outcome for dogs with TVD is generally good if their condition is diagnosed and treated early. With proper medical care, many dogs can live a normal long life. Some dogs will need lifelong care to manage their condition.
Symptoms of Canine Tricuspid Valve Dysplasia (TVD)
The most common symptom of TVD is a heart murmur, which is an abnormal sound heard through a stethoscope. Other signs and symptoms can include:
- Exercise intolerance
- Coughing
- Difficulty breathing
- Abdominal swelling due to fluid accumulation (ascites)
- Fainting or collapsing
- Weakness or lethargy
- Weight loss
- Pale gums
- Rapid heart rate (tachycardia)
- Abnormal heart rhythms (arrhythmias)
- Heart failure
Diagnosing Canine Tricuspid Valve Dysplasia (TVD)
TVD is typically diagnosed through a combination of physical examination, chest X-rays, echocardiography (an ultrasound for the heart), and electrocardiogram (ECG). During the physical exam, your veterinarian will listen to your dog’s heart for heart murmurs. Chest X-rays can help give an overall picture of the size and shape of their heart, as well as any fluid accumulation in their lungs or abdomen.
Stages of the Canine Tricuspid Valve Dysplasia (TVD)
TVD is typically split into three stages based on the severity of their disease.
Stage 1
Mild tricuspid valve dysplasia is associated with a mild leak in the tricuspid valve.
Stage 2
Moderate tricuspid valve dysplasia is associated with a moderate leak in the tricuspid valve.
Stage 3
Severe tricuspid valve dysplasia is associated with a severe leak in the tricuspid valve.
Treatment for Canine Tricuspid Valve Dysplasia (TVD)
Treating TVD depends on the severity of their disease, but can include medications to reduce fluid accumulation and improve heart function, as well as surgery to repair or replace the affected valve.
Medications
Medications are often used to reduce fluid accumulation in their chest and improve heart functions. Commonly prescribed medications include diuretics, ACE inhibitors, beta blockers, and antiarrhythmic drugs.
Surgery
In some cases, surgery will be necessary to repair or replace the affected valve. Surgery is typically recommended for dogs with severe TVD that are not responding to medical treatment.
Preventing for Canine Tricuspid Valve Dysplasia (TVD)
There is no known way to prevent TVD. It’s important to have your dog screened for heart disease during routine veterinary visits.
Early diagnosis and treatment can help improve the life of affected dogs.
Additional Information
Canine Tricuspid Valve Dysplasia (TVD) is a serious condition that can have serious consequences if left untreated. It’s important to work closely with your veterinarian to ensure your dog receives the best possible care.
