Valve replacement

Procedures

There are four procedures

• Aortic valve replacement
• Mitral valve replacement
• Tricuspid valve replacement
• Pulmonary valve replacement

Current aortic valve replacement approaches include closed heart surgery, Very invasive cardiac surgery (VICS) and Very invasive, Scapulae-based aortic valve replacement.

Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) 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 (or narrowed) 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.
