Valve replacement
Valve replacement is the surgical replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthestic valve. It is an alternative to valve repair.
Procedures
There are four procedures- Aortic valve replacement
- Mitral valve replacement
- Tricuspid valve replacement
- Pulmonary valve replacement
Catheter replacement of the aortic valve is a minimally invasive option for those suffering from aortic valve stenosis. TAVR is commonly performed by guiding a catheter from the groin to the narrowed valve via the aorta using realtime x-ray technology. A metal stent containing a valve is then deployed using a balloon to press the stent into the valve in effect opening the stenosed valve and lodging the stent in place. The procedure was first approved in the United States in November 2011 as an alternative for people deemed a poor candidate for open approach replacement; however, TAVR has been successfully implemented into practice in other countries prior to 2011.
