  2. Transcatheter aortic valve replacement - Wikipedia

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

    The transfemoral approach requires the catheter and valve to be inserted via the femoral artery. Similar to coronary artery stenting procedures, this is accessed via a small incision in the groin, through which the delivery system is slowly fed along the artery to the correct position at the aortic valve.

  3. Aortic valvuloplasty - Wikipedia

    en.wikipedia.org/wiki/Aortic_valvuloplasty

    Aortic valvuloplasty relies on placing a catheter with a balloon at the tip in the aortic valve, which is then inflated to widen the narrowed valve. [1] In order to reach the aortic valve, a blood vessel is punctured to introduce the catheter and advance it into the aortic valve. The most common site of entry is the femoral artery in the groin ...

  4. Aortic valve replacement - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_replacement

    Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .

  5. Valve replacement - Wikipedia

    en.wikipedia.org/wiki/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.

    He returned to UBC to work as an interventional cardiologist at St. Paul's Hospital in 1990. [7] After the world's first transcatheter aortic valve implantation was performed using an antegrade transseptal approach by Prof. Alain Cribier in 2002 at the University of Rouen, Webb developed the transapical and retrograde transfemoral transcatheter aortic valve implantation in 2006 at St. Paul's ...

  7. Minimally invasive cardiac surgery - Wikipedia

    en.wikipedia.org/wiki/Minimally_invasive_cardiac...

    Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.
