title: Treatment of a giant coronary aneurysm with a novel technique: scaffolding (tunnel) stenting to support PTFE-covered stents: insights from intravascular ultrasound.
abstract: This report describes a patient with progressive angina and a giant coronary aneurysm in the right coronary artery. Percutaneous treatment was performed using a novel technique consisting of implantation of a long stent that provided  scaffolding  or bridge for the subsequent implantation of two polytetrafluoroethylene-covered stents. Complete closure of the aneurysm was successfully achieved. In the angiogram performed 3 months later for recurrent angina, a localized narrowing at the distal stent edge (corresponding to severe underexpansion of the stent struts on intravascular ultrasound) was observed. This was successfully treated with balloon angioplasty. The technical details of this new technique are described.
