The U.S. FDA has approved an expanded indication for the Sapien 3 Transcatheter Heart Valve (THV) for patients with symptomatic heart disease, due to failure of a previously placed bioprosthetic aortic or mitral valve whose risk of death or severe complications from repeat surgery is high or greater.
“For the first time, a regulatory agency is approving a transcatheter heart valve as a valve-in-valve treatment when bioprosthetic mitral or aortic valves fail in patients who are at high or greater risk of complications from repeat surgery,” says Bram Zuckerman, MD, director of the division of cardiovascular devices at the FDA’s Center for Devices and Radiological Health. “This new approval offers U.S. patients with failing surgical bioprosthetic aortic or mitral valves a less-invasive treatment option.”
The FDA originally approved the Sapien 3 THV for transcatheter aortic valve replacement (TAVR) as an alternative option to surgical aortic valve replacement for patients with native aortic stenosis whose risk for death or severe complications from surgery is high or greater. In 2016, the FDA expanded the approved the TAVR indication for Sapien 3 THV to include patients who are at intermediate surgical risk for death or complications.
Now, the FDA is the first to approve an expanded use of the Sapien 3 THV as a valve-in-valve treatment. Valve-in-valve procedures offer an alternative to repeat surgery, since the replacement valve is inserted inside the failing surgical bioprosthetic valve through a patient’s blood vessel or a small cut in a patient’s chest.
The FDA evaluated data from the Transcatheter Valve Therapy Registry, a partnership of the American College of Cardiology and the Society of Thoracic Surgeons. The registry collects clinical data on the safety and effectiveness of transcatheter valve replacement procedures performed in a real world setting. The outcome data used to support the marketing application consisted of 314 patients who had undergone aortic valve-in-valve procedures and 311 patients who had undergone mitral valve-in-valve procedures.
The FDA granted the approval of Sapien 3 THV to Edwards Lifesciences LLC.
