Mitral Valve Repair Surgery

Mitral Valve

What is Mitral Regurgitation?

The mitral valve prevents back flow and supports the function of the left ventricle (main pumping chamber of the heart). When it fails to close properly, it allows the blood to backward into the upper left chamber of the heart (left atrium). Leakage increases blood volume and pressure in the left atrium. If the regurgitation is severe, the increased pressure results in congestive heart failure (fluid build-up in the lungs).

Common clinical presentations of congestive heart failure include: cough, lethargy, exercise intolerance, shortness of breath, syncope and sometimes death.

What is Mitral Valve Repair Surgery?

Mitral valve repair is the gold standard treatment for mitral valve disease in human medicine. Due to its limited availability in veterinary medicine, dogs usually receive palliative medical treatment. However, surgery is the only option to improve/fix the disease and offer long-term survival. The aim of the surgery is to restore the mitral valve leaflets coaptation and reduce the regurgitation of blood, thus reducing the stress on the heart. The surgery involves a mitral annuloplasty and artificial chordal replacement.

Mitral Valve Repair surgery requires stopping the heart beating to allow its repair. In order to maintain the circulation and oxygenation of the other organs, a cardiopulmonary bypass (CPB) machine is used. The CPB machine circulates and oxygenates blood for the body while bypassing the heart and lungs. This surgery incorporates two components: mitral annuloplasty and artificial chordal replacement.

Is my dog a suitable candidate for mitral valve repair?

To evaluate your pet’s suitability for the surgery, a series of examinations will be performed. It includes a thorough physical examination, comprehensive blood tests, urinalysis, electrocardiogram, chest X-rays, echocardiography and an abdominal ultrasound. All those tests can be conducted by your local vet and cardiologist. Based on those test results and the staging of heart disease, we will determine if your pet is a suitable candidate for the surgery.
