I am happy to note that the first of my papers with the Atrial Fibrillation Group at the University of Utah was published!  The full text can be found here.  While I know that I have an obvious bias, the paper is still very important.  It describes the University of Utah’s methodology for visualizing tissue damage following the ablation.  Further, it lays the groundwork for the next studies: the detection of low voltage tissue prior to ablation, and the determination of what ablation parameters will result in the induction of scar.  All in all, a nice little paper.

As an add on interest, we found that the degree of enhancement (or damage) seemed to relate to how well people did following the procedure.  There are a lot of theories flying around as to why this might be the case.  My own personal theory is that targeted ablation induces a change in diseased tissue.  I was also happy to notice that we aren’t the only people who see it as such.  Our study was of sufficient interest that it was accompanied by editorial comment, as a highlighted article.  Not bad, if I might be allowed a smug moment.

For those that care about such things, here is the citation:
