During a full day of presentations on TADs, world experts will present their systems, their concepts, their cases, and their data, almost certainly with impressive results. But at the end of the day, there are bound to be more questions than answers. This presentation will summarize the day's presentations and recent literature with regard to the presentations. In particular, factors that appear to be important to TAD success, that is, factors that allow a TAD to be placed and used for the entire duration of which it was intended without coming loose, or failing, will be outlined and summarized.
