Finding out that your pet needs heart surgery can be overwhelming. It is a moment filled with anxiety and questions about what comes next. In veterinary cardiology, there are two primary approaches considered for treating severe valve issues: traditional open-heart surgery and the transcatheter edge-to-edge repair (TEER) procedure.

While both aim to restore your pet’s heart function, they differ fundamentally in their approach, invasiveness and recovery profiles. Knowing the mechanics and implications of each method can help you feel more prepared and informed about what to expect during your pet’s recovery journey.

What Is the TEER Procedure?

The TEER procedure is a minimally invasive treatment designed to treat mitral valve regurgitation (a leaky heart valve) without the need to open the chest or use a heart-lung bypass machine.

Instead, the surgeon accesses the heart through a small puncture in the chest wall to reach the apex (tip) of the heart. Using transoesophageal echocardiography (ultrasound) for guidance, a specialised device called a V-Clamp is advanced to the heart. This clamp brings the leaflets of the mitral valve together, reducing the backflow of blood (regurgitation) that causes heart failure.

When Is It Recommended?

The TEER procedure is often considered for older pets or those with underlying health conditions that make them higher-risk candidates for open-heart surgery and cardiopulmonary bypass. It is particularly effective in cases of advanced mitral valve disease, including myxomatous mitral valve disease (MMVD) in dogs, especially in Stage C or D, where symptoms are more pronounced.

However, not all pets are suitable candidates. The structure and condition of the mitral valve must allow for proper placement of the device. In cases where the valve is severely damaged or anatomically unsuitable, alternative treatment options may need to be explored.

Expected Recovery

The recovery profile for TEER is shorter than that of traditional surgery. Pets often experience less post-operative pain and may be discharged from the hospital within 2–3 days. While rest is still required, many owners report seeing an immediate improvement in their pet’s energy levels and breathing.

What Is Traditional Heart Surgery?

Traditional heart surgery, often referred to as open-heart surgery, involves a direct surgical approach to repair or replace damaged structures within the heart. This is a major surgical event that requires general anaesthesia and the use of a heart-lung bypass machine.

During the procedure, the veterinary surgeon makes a large incision through the chest bone (sternum) to access the heart directly. To operate on the heart while it is still, a cardiopulmonary bypass machine is typically used. This machine temporarily takes over the work of the heart and lungs, pumping oxygenated blood through the body while the surgeon repairs the valve or corrects the defect.

When Is It Recommended?

Traditional surgery is generally recommended for pets with complex congenital defects, for removing tumours, or for repairing structural issues that cannot be reached or fixed via a catheter. However, because of the physical toll it takes on the body, pets must be in relatively good overall health to withstand the use of anaesthesia and the bypass machine.

Expected Recovery

Because this is a major surgery involving a chest incision and heart bypass, the recovery period is extensive. Pets usually remain in the hospital for a week or more for close monitoring. The healing process for the chest bone can be painful and takes several weeks to months, requiring strict rest and restricted movement.

At A Glance: TEER Procedure vs. Traditional Heart Surgery

Invasiveness
TEER Procedure

Minimally invasive; performed through a small entry point without opening the chest

Traditional Surgery

Highly invasive; requires opening the chest and the use of a heart-lung bypass machine

Recovery Time
TEER Procedure

Shorter recovery; many pets are discharged within 2–3 days

Traditional Surgery

Longer recovery; may require hospitalisation for a week or more with extended rest

Risk Profile
TEER Procedure

Generally lower risk, especially for older pets or those with other health conditions

Traditional Surgery

Higher risk due to major surgery and use of cardiopulmonary bypass

Suitability
TEER Procedure

Best for specific conditions like myxomatous mitral valve disease (MMVD), depending on valve anatomy

Traditional Surgery

Suitable for complex structural defects or conditions not treatable via minimally invasive methods

The most suitable option depends on your pet’s condition, overall health and the recommendation of your veterinary team.

Choosing the Right Heart Treatment for Your Pet

Choosing between traditional surgery and the TEER procedure is a decision best made through collaboration between the pet owner and the veterinary team. This process often involves a comprehensive internal medicine evaluation to ensure the chosen treatment supports your pet’s overall heart health.

Here at Advanced Vetcare, we strive to offer holistic care for all pets to ensure the best possible outcomes. Led by Dr Nicholas Woo, our team is committed to guiding you through every step from diagnosis to treatment and recovery. If you are exploring heart treatment options for your pet, schedule a consultation with us for a comprehensive assessment and tailored care plan.
