   en.wikipedia.org/wiki/Transcatheter_aortic_valve...

   Transcatheter aortic valve replacement (TAVR) is the implantation of the aortic valve of the heart through the blood vessels without actual removal of the native valve (as opposed to the aortic valve replacement by open heart surgery, surgical aortic valve replacement, AVR).

3. Aortic valve replacement - Wikipedia

   en.wikipedia.org/wiki/Aortic_valve_replacement

   Current methods for aortic valve replacement include open-heart surgery, minimally invasive cardiac surgery (MICS), surgical aortic valve replacement (SAVR) and percutaneous or transcatheter aortic valve replacement (TAVR; also PAVR, PAVI, TAVI). A cardiologist can evaluate whether a heart valve repair or valve replacement would be of benefit. [1]

   en.wikipedia.org/wiki/Valve_replacement

   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.

5. Aortic valve area calculation - Wikipedia

   en.wikipedia.org/wiki/Aortic_valve_area_calculation

   In cardiology, aortic valve area calculation is an indirect method of determining the area of the aortic valve of the heart. The calculated aortic valve orifice area is currently one of the measures for evaluating the severity of aortic stenosis. A valve area of less than 1.0 cm 2 is considered to be severe aortic stenosis. [1] [2]

   One animal trial combined the transcatheter aortic valve replacement (TAVR) procedure with tissue engineered heart valves (TEHVs). A TAVR stent integrated with human cell-derived extracellular matrix was implanted and examined in sheep, in which the valve upheld structural integrity and cell infiltration, allowing the potential clinical ...
