[HSF] ATS valve

[bbiocina at kbd.hr]

This is one  of key papers  that explain  orientation policy in 
mechanical prostheses. According to Laas , bileaflet prosteses should be
implanted  with one  opening  underneath  the previous right coronary 
sinus, and thet allegedly produces best  hemodynamic results ( we do the
same in Dubrava  since 1999)


Orientation of tilting disc and bileaflet aortic valve substitutes for
optimal hemodynamics.
Laas J, Kleine P, Hasenkam MJ, Nygaard H. Ann Thorac Surg.
1999;68:1096-1099.
