#2 Percutaneous Aortic Heart Valves

Overview

For high-risk patients, a technique has been developed that involves inserting a new expandable wire mesh valve with internal valve leaflets. The valve is inserted through a groin or small chest wall incision and then fed up through a catheter into position with X-ray screening. The balloon is inflated to secure the new valve.
 
The percutaneous insertion of aortic valve prostheses are quickly becoming a viable treatment option for high-risk cases, while increasing experience and improved instrumentation will lead to its adoption in elective cases as well. Different versions of this technology are now undergoing clinical trials in the U.S., while the total worldwide experience now numbers in the thousands.

Where Are They Now

For high-risk patients, a technique has been developed that involves inserting a new expandable wire mesh valve with internal valve leaflets. These valves can be inserted through blood vessels in the groin and threaded into the heart or through a small chest wall incision.

There are now four aortic valve devices that are FDA approved for percutaneous repair or replacement, and the technology has expanded to percutaneous mitral valve repair with devices in clinical testing this year. In 2016 a new FDA trial for percutaneous aortic heart valves was approved with attention to large bore vascular closure. The trial aims to look at the safety of the procedure with the use of large bore vascular closing devices as developed by the medical device company leading the trial.
