TEER reduces mitral leakage without open-heart surgery
A catheter-based device grasps portions of the mitral leaflets to improve their meeting point and reduce regurgitation. The procedure is guided by transesophageal echocardiography.
Primary degenerative and secondary functional regurgitation have different selection pathways. Anatomy, symptoms, ventricular size and function, pulmonary pressure and surgical risk must be assessed together.
For functional mitral regurgitation, guideline-directed heart-failure and rhythm treatment should be reviewed before TEER benefit is estimated.
Who may be considered?
Specialist review may help when the diagnosis, symptoms and previous treatment create a focused question about transcatheter edge-to-edge mitral repair.
- Severe symptomatic primary regurgitation with high surgical risk and suitable anatomy.
- Selected secondary regurgitation despite optimized heart-failure therapy.
- A patient requiring multidisciplinary comparison of TEER and surgery.
- Persistent symptoms where regurgitation is a major, treatable contributor.
What the specialist team must confirm
The structural heart team reviews transthoracic and transesophageal echo, leaflet anatomy, jet location, valve area and gradient, ventricular dimensions and function, pulmonary pressure, coronary disease, heart-failure treatment and surgical risk.
Key points for this treatment

From mechanism-based assessment to image-guided repair
TEER is used when the expected symptom or outcome benefit justifies residual leakage and procedural risk.
Follow both the valve result and the heart-failure pathway
Early echo evaluates residual regurgitation, valve gradient and pericardial or vascular complications.
Later care continues heart-failure treatment, rhythm and volume management, symptom review and interval echocardiography.

Risks, limits and realistic expectations
Risks include bleeding, vascular injury, stroke, cardiac perforation, device detachment, residual regurgitation, mitral stenosis, emergency surgery and death. TEER may reduce but not eliminate leakage.
New severe breathlessness, chest pain, fainting, stroke symptoms or rapidly worsening swelling needs urgent local care.
