Aortic Stenosis

Understanding Aortic Stenosis in Pets: A Complete Parent’s Guide

Aortic Stenosis (AS) is a serious, often inherited, heart condition that can affect any small animal, though it is most common in dogs, especially large breeds like Golden Retrievers, Boxers, and Newfoundlands. In cats, a similar but rare condition can also occur. AS happens when the passage just below the aortic valve—the main blood vessel carrying blood from the heart to the body—becomes narrowed.

This narrowing forces your pet's heart to work much harder, like trying to force water through a kinked hose. Over time, this extra strain causes the heart muscle to thicken (a condition called left ventricular hypertrophy), which can lead to heart failure or a shortened lifespan if left untreated.

Symptoms of Aortic Stenosis

Many pets with mild AS show no obvious signs, making early detection crucial during routine vet check-ups. When symptoms do appear, they can include:

• A heart murmur (often the first sign, detected during a vet exam).
• Lethargy or unwillingness to exercise.
• Fainting (syncope) or sudden collapse.
• In severe cases, sudden death.

If your vet hears a heart murmur in your pet, it's essential to seek further diagnostic testing.

How We Diagnose Aortic Stenosis at MaxPetZ

At MaxPetZ, our veterinary cardiology team uses advanced diagnostic tools to confirm and assess the severity of AS in both dogs and other small animals. These tests are vital for creating the best treatment plan.

• Echocardiogram (Heart Ultrasound): This is the most important diagnostic tool. It allows our specialists to see the heart in real-time, visualizing the narrowing, measuring blood flow velocity, and assessing the extent of muscle thickening.
• Electrocardiogram (ECG): This test checks for any irregular heart rhythms that might be present.
• Chest Radiographs (X-rays): These images help us evaluate the overall size of the heart and check for any fluid buildup in the lungs, which can be a sign of heart failure.

Treatment Options for Aortic Stenosis

The treatment approach for AS depends on the severity of your pet’s condition.

• Medical Management: For mild cases, we may only need to monitor your pet and use medications to help their heart work more efficiently and reduce its workload.
• Balloon Valvuloplasty: The Gold Standard: For severe AS, Balloon Valvuloplasty is the most effective and a minimally invasive procedure we offer. This non-surgical procedure involves inserting a tiny catheter with a balloon on its tip into the heart. Once in the narrowed area, the balloon is gently inflated, stretching the passageway and allowing for better blood flow. The balloon is then deflated and removed, leaving the valve more open and relieving the strain on your pet's heart.

This advanced procedure provides immediate relief and significantly reduces the risk of life-threatening events, offering a chance at a much longer, healthier life.

After the Procedure: Recovery and Long-Term Care

Following the procedure, your pet will be closely monitored in our Critical Care Unit to ensure a smooth recovery. A follow-up echocardiogram will be performed to confirm the procedure's success. We will then work with you on a long-term care plan, including regular check-ups, to ensure your pet’s continued heart health.
