[HSF] ATS valve

[hgrmd at aol.com]

Prasanna,

  I've been using ATS mechanicals for about the last 3 years.  No problems so far.  The thing I like about it is the ability to reliably rotate it.  In addition, I've had no problems with leaflet impingement which was a problem with the St. Jude Regent.  For small calcified mitral annuli, they have an AP valve that sits on top of the valve orifice.  This is a life saver if you are faced with an orifice smaller than 25 mm.

We implanted our units first ATS valve last week.(The so called advanced performance valve) Seemed OK and patient had low gradients etc (AVR) Can members who ave implanted it tell me about their experiences especially the good the bad and the ugly (More interested in the last two). 
One thing I noted when we were implanting the valve was that we had sized it to a 24 AP (actually 26 sizer went in but 24 was the largest size supplied) and it did take a bit of effort to get it in (though once in it fit well). I was a bit worried at that time that it may have been "oversized" wrt to the sizer. 
Is there any 'preferred " position in literature wrt bilealfet valves in the aortic position. (I am aware of the position wrt monoleaflet valves but could not really get any data for bileaflet valves).
