Aortic valve replacement is a procedure in which a patient's failing aortic valve is replaced with an artificial heart valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis). Current aortic valve replacement approaches include open heart surgery via a sternotomy, minimally invasive cardiac surgery (MICS) and transcatheter aortic valve replacement (TAVR).
