Combination Tools for Calcium Modification from RASER to Orbitalshock

Jonathan Hinton et al. Interv Cardiol. .

Abstract

Coronary artery calcification is frequently encountered during percutaneous coronary intervention and its presence is associated with a higher risk of stent under-expansion which has been associated with long-term risk of stent failure. There are several different calcium modification strategies available, whether they be balloon-based devices (cutting/scoring and intravascular lithotripsy) or atherectomy devices (orbital atherectomy, rotational atherectomy, excimer laser coronary atherectomy) that are established for the modification of coronary calcification. Each strategy applies a different mechanism of action for calcium modulation and consequently the potential to combine modifying tools may offer synergistic advantages over device monotherapy. This article will focus on reviewing the evidence for the use of multiple calcium modification techniques and examine whether there really is any such synergistic effect of combining these tools.

Keywords: Calcium modification; coronary artery disease; coronary intervention.
