Coronary Stenting in Vessels with Marked Proximal Tortuosity Using a Sport Wire: Advantages and Pitfalls

In this report two patients are described in whom successful deployment of a coronary stent was achieved in a very tortuous coronary artery. Deployment was performed using a special extra-support wire that straightened the proximal segment of the artery and provided the support for stent advancement. The mechanical straightening of the artery induced marked narrowing that did not respond to intracoronary nitroglycerin but disappeared after withdrawal of the wire.
