Diagnostics Service

TeleCardiology by CVCA is a cardiac diagnostics service available for asymptomatic (stable) pets only, We do not have direct onsite veterinary supervision.

  • We cannot see highly anxious pets that require sedation administered by a veterinarian.

  • Please discuss with your primary care veterinarian if TeleCardiology by CVCA is right for your pet.

If your pet is experiencing symptoms or clinical signs, please take your pet to urgent care for immediate stabilization of their cardiac symptoms and condition.

Diagnostics Service

Get The Facts

Here are a few of the typical questions, with answers, that you may have about your upcoming appointment.

How long is a typical TeleCardiology by CVCA appointment?

A typical appointment is about 1 hour long. This allows us to get your pet checked in, take a blood pressure reading, and capture a series of high-quality echocardiogram images of your pet for detailed evaluation by our cardiologist.

What is an echocardiogram?

An echocardiogram is an ultrasound of the heart. It is considered the “Gold Standard” of diagnostics and is how our cardiologist obtains the best information regarding your pet’s heart. It is a painless procedure to your pet and gives a clear understanding of your pet’s heart function.

Will I get a treatment plan for my pet?

Yes. You will get a treatment plan through your primary care veterinarian. Our cardiologist will share a comprehensive report that provides thorough diagnostics, prognosis and treatment plan recommendations to your primary care within 48 business hours of your appointment. Your primary care will contact you and share this information as part of your pet’s holistic care plan.

What happens after the imaging appointment?

Your primary care doctor will contact you with the findings and care plan for your pet. If there are any medications, additional tests or therapies needed, your primary care veterinarian will help you get the information, any medications or additional tests to provide follow up care from the appointment.

Will the onsite TeleCardiology Imaging team be able to answer my medical questions about my pet’s cardiac care?

No. The TeleCardiology Imaging team is here to provide diagnostic testing (imaging and related information) to the CVCA Cardiologist to complete a full evaluation and assessment. The team providing the imaging onsite are available to help make your pet comfortable and to collect the information for the doctor. The team is not trained and qualified to provide medical assessments.

Think of this appointment as being similar to if you need to get an X-Ray image for a potential bone fracture, which is sent to your doctor for professional medical assessment and treatment care.

My pet is symptomatic and/or in distress. Can you provide care to their cardiac health?

No. If your pet is symptomatic and/or in great distress, you should seek immediate care at your local veterinary emergency clinic. This is a diagnostic service to provide insights and recommendations for care of cardiac issues, or to provide cardiac clearances for other procedures.

My pet is highly anxious, and may not remain calm for the echocardiogram. How should I handle that?

If your pet has mild anxiety that can be easily managed with sedatives, discuss options with your primary care veterinarian prior to the imaging appointment.

If your pet is very anxious and there is a risk that we cannot get the imaging successfully captured without full sedation, we cannot perform an echocardiogram. We do not have a doctor on premise who can provide that higher level of sedation management support to capture images.

Do you have the cardiologist on premise that I can speak with during the appointment?

No. The cardiologist is not on premise at our TeleCardiology by CVCA imaging center.

Can I be in the room with my pet during the echocardiogram?

No. This is simply a diagnostic imaging appointment to capture high-quality images for diagnostic and care recommendations. Our team is highly-trained to provide exceptional care to your pet and capture clear images efficiently. We will keep you apprised of progress and bring your pet to you as soon as we get the images the cardiologist will need.

How can I schedule appointments directly with TeleCardiology by CVCA (for other pets, for example)?

TeleCardiology by CVCA is a referral-based service. That means, we only accept patients who were referred to us by a primary care veterinarian.

If you think you need an appointment for a pet, please contact your primary care veterinarian for a potential referral to TeleCardiology by CVCA and we’ll get you set for an appointment.

When will I get information on a diagnosis and treatment plan for my pet's cardiac care?

In most cases, you leave the appointment with this information; or you will receive the detailed information in your email within 24 hours of the appointment.  We provide you with all the information you need for your pet's cardiac care so you can begin treatment plans and know more about your pet with the appointment.

How does my primary care veterinarian know what is going on with my pet's cardiac care?

We send them a detailed report and keep them completely in the loop regarding cardiac care -- often the same day of your appointment. CVCA works with our partners in primary care through a co-managed care philosophy: as expert specialists in cardiac care, we provide all the information you and your primary care need on your pet's cardiology care.  Your primary care is still the hub of your pet's healthcare and factors in this cardiology information with all the other healthcare your pet receives.
