Transcatheter Edge-to-Edge Repair (TEER)

Transcatheter Edge-to-Edge Repair (TEER), formerly known as Transcatheter Edge-to-Edge Clipping (TEC), is a minimally invasive procedure used to treat mitral valve regurgitation. This procedure is particularly beneficial for patients who are at high risk for traditional open-heart surgery. TEER involves the use of a catheter-based system to place a clip on the mitral valve, thereby reducing the backflow of blood and improving heart function.

Background

Mitral valve regurgitation is a condition where the mitral valve does not close properly, allowing blood to flow backward into the left atrium when the left ventricle contracts. This can lead to symptoms such as shortness of breath, fatigue, and heart palpitations. If left untreated, it can result in heart failure or other serious complications.

Traditional treatment for severe mitral valve regurgitation involves surgical repair or replacement of the valve. However, many patients, especially the elderly or those with comorbidities, may not be suitable candidates for surgery. TEER offers a less invasive alternative.

Procedure

The TEER procedure is performed in a cardiac catheterization laboratory. It involves the following steps:

1. Access: A catheter is inserted through the femoral vein in the groin and guided to the heart. 2. Positioning: Using echocardiographic and fluoroscopic guidance, the catheter is positioned at the mitral valve. 3. Clipping: A clip is deployed to grasp the leaflets of the mitral valve, creating a double orifice and reducing regurgitation. 4. Assessment: The effectiveness of the clip is assessed using echocardiography to ensure adequate reduction of regurgitation. 5. Closure: The catheter is removed, and the access site is closed.

Indications

TEER is indicated for patients with symptomatic, moderate-to-severe or severe mitral valve regurgitation who are considered high-risk for surgical intervention. It is particularly useful for patients with:

- Degenerative mitral regurgitation - Functional mitral regurgitation - Previous cardiac surgery

Outcomes

Clinical studies have shown that TEER can significantly reduce mitral regurgitation, improve symptoms, and enhance quality of life. The procedure has a lower risk of complications compared to open-heart surgery and offers a quicker recovery time.

Complications

While TEER is generally safe, potential complications include:

- Vascular complications at the access site - Residual mitral regurgitation - Device embolization - Need for subsequent surgical intervention
