Pulmonic Stenosis In Cats: Symptoms, Causes, & Treatments

Pulmonic stenosis in cats is a medical condition that causes issues with the way blood can flow through a cat’s pulmonary valve in the heart. The valve thickens and narrows, slowing blood flow through the valve and into the pulmonary artery.

This might be an uncommon condition, but it can also lead to congenital heart failure in certain circumstances.

If you see signs that your kitty might be developing heart or circulation issues, then you must consult your veterinarian for a proper diagnosis and advice. Here’s what you should know about the symptoms, causes, and treatments of pulmonic stenosis in cats.

Symptoms Of Pulmonic Stenosis In Cats

Pulmonic stenosis in cats can produce different symptoms depending on which exact type a feline is diagnosed with. In general, some of the most common symptoms include:

  • Reluctance to exercise
  • Breathing issues
  • Swollen abdomen (also known as abdominal distention)

The cause of pulmonic stenosis in cats is congenital, which means that kittens are born with the condition.

Veterinary Treatments

If you suspect that your cat might be suffering from pulmonic stenosis, your veterinarian will want to ask about your cat’s full medical history and then carry out a physical examination. They’ll take blood and urine tests, which can also be useful in ruling out other conditions.

The vet will likely also recommend the use of X-rays and other imaging techniques to properly examine your kitty’s heart and abdomen.

When it comes to treatment, the precise course will often be related to the extent of the condition and how badly a cat’s heart valve is being obstructed. Severe cases might require a period in hospital, and vets may consider a surgical procedure called a valvuloplasty to help alleviate any obstruction to the valve.

While your cat recovers at home, your vet might suggest medication to help the process. As always, if your vet prescribes your cat any medicine, it is vital that you stick to the precise frequency and dosage instructions and complete the full course of medication.
