Adenosine‐induced temporary block to improve accuracy of ostial coronary stent implantation: Adenosine to improve stent implantation accuracy

Implantation of coronary stents should be performed with high precision to ensure optimal clinical results. In some clinical conditions, during the cardiac cycle, significant movement of the predeployed stent may impact its implantation accuracy. We describe a case in which a patient had a short ostial left anterior descending artery stenosis and hyperkinetic left ventricle, resulting in significant movement of the stent inside the vessel lumen during the cardiac cycle. Intracoronary adenosine was used to create temporary heart block to enable accurate stent implantation.© 2013 Wiley Periodicals, Inc.
