ABOUT THE THERAPY TRANSCATHETER AORTIC VALVE IMPLANTATION (TAVI)

MINIMALLY INVASIVE ALTERNATIVE FOR SEVERE AORTIC STENOSIS

A changing paradigm in the management of patients with severe aortic stenosis, transcatheter aortic valve implantation (TAVI) is a minimally invasive, catheter-based procedure to replace the aortic valve. Prior to TAVI, treatment options were limited to:

• Temporarily improving valve function and easing symptoms by prescribing medication and performing a BAV procedure
• Replacing the diseased valve in an open-heart surgery (surgical aortic valve implantation)

TAVI does not require open-heart surgery. Instead, with TAVI, the heart is accessed via an artery. There are three access options:

1. Transfemoral
2. Subclavian
3. Direct aortic

Using imaging and a delivery system, the physician threads the compressed bioprosthetic heart valve through the catheter and positions it within the diseased valve.

After positioning the bioprosthetic valve, the physician begins deploying the valve; the middle image below shows a partially expanded valve. When deployment is complete, the bioprosthetic valve is fully expanded within the diseased native valve.

THE MEDTRONIC ADVANTAGE

Today, TAVI is a proven procedure that can prolong lives.  At Medtronic, we believe it is the choice for patients who can return to an active life.

We've designed the Evolut platform to achieve industry-leading hemodynamics, which are important to younger, more active patients.
