Angulated Lesions

 * Balloon angioplasty of highly angulated lesions is associated with an increased for risk coronary dissection.


 * In the settings of coronary stenting, angulated lesions represent a challenge due to the inability of delivering the stent to the stenosis and straightening of the arterial silhouette after stent implantation that may predispose to the presence of stent fracture.


 * Vessel curvature at the site of maximum stenosis should be measured in the most unforeshortened projection using a length of curvature that approximates the balloon length used for coronary dilation.
