Cardiology access in Maine
We have verified exactly one board-certified veterinary cardiologist practising in Maine, in Portland. A single specialist for an entire state has practical consequences: appointment books fill weeks out, there is no in-state second opinion available, and if that practice is not taking new referrals you are looking at a drive across the state line rather than a wait.
The single Maine practice listed below was accepting new patients when we last checked. Check by phone before you drive: availability changes faster than any directory can track, and a cardiologist listed as accepting referrals may still have a six-week wait for a non-urgent echo.
Context for those numbers: fewer than 400 board-certified veterinary cardiologists (DACVIM-Cardiology) practise in the entire United States. Board certification requires a veterinary degree, a one-year internship, a three- to four-year cardiology residency, and passing the ACVIM cardiology examination. Scarcity, not indifference, is why the wait lists look the way they do.
Maine has one listed cardiologist, in Portland, and no veterinary college. For owners north of Bangor, greater Boston is realistically the nearest concentration of cardiology capacity.
The nearest veterinary teaching hospital to Maine
Maine does not have an accredited college of veterinary medicine. That matters because teaching hospitals are frequently cheaper than private specialty practice, run most of the veterinary cardiology clinical trials, and often have capacity when private referral centres do not. The closest options for Maine owners are:
- Cummings School of Veterinary Medicine at Tufts University — North Grafton, Massachusetts
Before you drive there, call and ask three things: whether the hospital currently runs a small-animal cardiology service (not every veterinary college does, and services open and close with staffing); whether they require a referral letter from your primary vet, which most teaching hospitals do; and whether any cardiac clinical trial is currently enrolling that your dog might qualify for — trial enrolment can cover the cost of echocardiograms and Holter monitoring that you would otherwise pay for.

What a cardiology workup costs in Maine
Prices are set practice by practice, so nobody can quote you a Maine figure that holds everywhere. As a working range in the United States, a specialist cardiology consultation with an echocardiogram typically runs somewhere around $300–$600, and a 24-hour Holter monitor somewhere around $200–$500 including the analysis fee. Expect the top of those ranges in high-cost metros and the bottom in smaller markets.
Veterinary teaching hospitals are usually the cheaper end of the market — worth weighing against the extra mileage if you are driving out of Maine anyway. Ask for an itemised estimate when you book, and ask specifically whether the echocardiogram fee includes the consultation or is charged on top of it. That single question accounts for most of the surprise on the invoice.
If cost is the blocker, read our guides on financial help for cardiac treatment and pet insurance and heart disease, and ask the practice about clinical trial enrolment before you decline the test.
Crossing the state line from Maine
Referral cardiology does not respect state boundaries, and for a lot of Maine owners the shortest wait is over the border rather than across the state.
Of the states bordering Maine, Massachusetts (3 cardiologists), New Hampshire (2 cardiologists) and Connecticut (2 cardiologists) havethe most listed capacity. If you live within an hour or two of the line, call across it before you accept a long wait at home — and bring a referral letter, since many specialty practices will not book an out-of-state first appointment without one.
What happens at a cardiology consultation
A first cardiology visit in Maine typically includes a physical exam with auscultation, an echocardiogram (heart ultrasound), sometimes a Holter monitor fitting for 24-hour rhythm analysis, and a review of any prior imaging or bloodwork. The cardiologist will stage your dog's disease (typically using the ACVIM staging system) and outline a treatment and monitoring plan. Budget 45–90 minutes depending on which tests are done, and arrive 15–20 minutes early for paperwork if you are a new patient.
The diagnoses that bring most dogs to a cardiologist are dilated cardiomyopathy (DCM), myxomatous mitral valve disease (MMVD), and arrhythmogenic right ventricular cardiomyopathy (ARVC). Depending on diagnosis and stage, the cardiologist may prescribe pimobendan or furosemide, and will usually set a recheck interval before you leave.
Preparing for your visit
- Bring any previous test results (Holter reports, echocardiograms, bloodwork)
- Write down all current medications and dosages
- Note any symptoms you've observed and when they started
- Track your dog's resting respiratory rate for a few days before the visit
- Print our 10 questions to ask your cardiologist
