This review summarizes guideline recommendations and novel strategies for choosing between mechanical and biological prostheses for aortic valve replacement.
Aortic valve replacement (AVR) is the most frequently performed procedure in valve surgery. The controversy about the optimal choice of the prosthetic valve is as old as the technique itself. Currently there is no perfect valve substitute available. The main challenge is to choose between mechanical and biological prosthetic valves. Biological valves include pericardial (bovine, porcine or equine) and native porcine bioprostheses designed in stented, stentless and sutureless versions. Homografts and pulmonary autografts are reserved for special indications and will not be discussed in detail in this review. We will focus on the decision making between artificial biological and mechanical prostheses, respectively. The first part of this article reviews guideline recommendations concerning the choice of aortic prostheses in different clinical situations while the second part is focused on novel strategies in the treatment of patients with aortic valve pathology.

Reineke et al. (2015) conducted a review in Aortic valve pathology. Mechanical versus biological aortic valve replacement was evaluated. This review summarizes guideline recommendations and novel strategies for choosing between mechanical and biological prosthetic valves in patients undergoing aortic valve replacement.
