End of life care and decision making

Interesting editorial in JAMA here:
jama.ama-assn.org/content/307/9/917.full

PFO and Cryptogenic Stroke

I read this with interest, having seen more and more PFOs closed in the absence of trial evidence, I am glad to see such an editorial hammer home the key point -- not without more study.
