My big worry about this is stents. I guess i'm hoping any problems there proves to be will be fixable via angioplasty(s) because the word "stent" brings me out in a cold sweat.
Just how safe are they? I guess we've all read about the one that travelled disasterously, but not just that, the question of blockages (this seems quite common) and just how dangeous is it if that happens? How easy is it to get back into the clinic at Poland if it does? Is it even safe to fly if one does become blocked? How worried should you be? You get my gist

The fact that they can just slip and end up anywhere terrifies me but I have no idea what the chances of this are.
We seem to have heard a lot about problems in America, but is the Polish clinic so far squeaky clean on a problematic basis?
Information along this err... vein would be very much appreciated because right now my brain needs to have a grip of the facts in this area. And i'd like to stop worrying so much (but not blindly)!

Thank you wonderful people for any/all help xxx
