Tricuspid Valve Dysplasia in Dogs… Symptoms, expectations and cost!

One rare heart disease for dogs is known as tricuspid valve dysplasia, and while that’s a good thing, it doesn’t change the fact that if your dog ends up getting diagnosed with it, you’re going to have a lot of questions. This is why we here at IndulgeYourPet wanted to include Tricuspid Valve Dysplasia (TVD) on our list of diseases found in dogs so that if you ever find yourself dealing with a dog with the condition, you’ll have a better idea about what to expect.

So, without further ado, let’s dive right in.

What is TVD?

TVD is a congenital heart disease. The word congenital means “from birth”. It may be genetic because it’s seen much more in certain breeds of dogs like Great Dane, Irish Settler, Labrador Retriever, Golden Retriever, and German Shepherd.

Cats cannot get TVD.

Normal Blood Flow Through the Heart

First, the blood is supposed to move from the superior and inferior vena cavas. After that, it goes to the right atrium and the tricuspid valve. Next, it goes on to the right ventricle. From there to the pulmonary artery and the lungs. From the lungs, it then goes back to the heart and through the left side, the left atrium, and the mitral valve to the left ventricle before going to the aorta. Movement through the ventricles is thanks to the papillary muscles.

Here’s what happens…

The congenital malformation occurs in the tricuspid valve complex, and there is a problem with the septal leaflet. As a result, there is a disruption to the blood flow; the blood experiences regurgitation back to the right atrium instead of to the right ventricle like it’s supposed to.

Clinical Signs & Symptoms of Tricuspid Valve Dysplasia in Dogs

Your dog won’t be able to tell you if they are having a murmur, so how do you find out that something might be wrong with tricuspid leaflets? Well, first, start with some signs and symptoms.

Dogs with TVD are more likely to:

  • Have stunted growth/ not grow to size.
  • Show signs of exercise intolerance (doesn’t like to run or play to the level their breed should).
  • I have a swollen abdomen.
  • Heavy breathing.

If they have mitral valve dysplasia, the symptoms are similar, though they may not have stunted growth and faint occasionally.


There is another heart valve malformation known as atrioventricular valve dysplasia. This impacts the atrium of the heart, which makes it different from TVD. Sometimes, the mitral valve doesn’t function right, called mitral valve dysplasia. A dog can have TVD and other heart diseases. This is quite common. In addition to mitral valve dysplasia, they may suffer from interventricular septum, subaortic stenosis, pulmonic stenosis, Ebstein anomaly, stenosis, or septal defects.

Diagnosis of Tricuspid Valve Dysplasia in Dogs

The only way to know if your dog has a pulmonary disease or septal defect is to take them to the vet. The vet will diagnose it after giving a heart exam and hearing their history. You may also have to give your dog an echocardiography (ECG) to check atrial dilation. The ECG is a great tool to help determine heart irregularities like arrhythmia. It can also help the doctor know if the heart’s left or right side is the problem.

Treatment of Tricuspid Valve Dysplasia in Dogs

Veterinary medicine may be the only thing needed in some cases. However, in more severe cases, your dog may even require surgery. As mentioned, there are a lot of different things that can be secondary conditions. Because of this, the treatment will depend on that. One thing’s for sure: whenever a dog has a heart condition, there will be many vet visits. Also, a dog with a heart condition is strongly recommended to be spayed or neutered.

Which brings us to…

We want to remind folks that we at IndulgeYourPet are not doctors, veterinarians, or medical professionals. We are all a bunch of folks passionate about animals and only want what’s best for them. This is why if you feel like your pet may have tricuspid valve dysplasia(or any other health issue), you’ll want to have them checked out by a vet ASAP!


An early diagnosis will often lead to the “best” medical outcome for your pet regardless of what is bothering them, but beyond that, diagnosing a medical condition early could save you a bundle of medical costs!

Cost of Tricuspid Valve Dysplasia in Dogs

Since we can’t say the exact treatment plan, it’s hard to guess the cost. If your dog has minimal heart problems, he’ll, at the very least, need an annual check-up, which is much more than most pets. That alone will cost $100-200. Tests like X-rays and ECGs will be another couple hundred—your vet might recommend these annually.

If it comes time for heart surgery, that will cost upwards of $ 1,000, probably closer to $ 5,000. As you can see, this can be expensive. But is there a price for your love for a human’s best friend? This is also why we here at IndulgeYourPet also recommend that any new pet owner take a moment and see what it might cost for you to purchase a pet insurance policy for your new animal.

Now, will a pet insurance policy be suitable for everyone?

No, probably not. But until you fully understand what these policies “will” and “won’t” cover and how much these pet insurance policies cost, how will you know if one might be right for you?
