Distal Protection Devices

  • David R. HolmesJr.


The role and importance of distal embolization in complications arising during percutaneous interventions are now considered well established; however, this is a relatively new concept [1]. Early in the evolution of interventional cardiology, distal embolization was not thought to be a significant problem [2,3]. Instead, the mechanism of dilatation was conceptualized as analogous to “stepping onto a layer of snow,” which was then compressed, with the procedure leading to larger lumen size without injuring the wall itself and without embolization.
