Maintenance of coronary guidewire position during guide catheter exchange.
Maintaining the position of a guidewire across coronary artery lesions during angioplasty is important to permit rapid and reliable access. This article describes a technique which enables a guide catheter to be replaced while maintaining coronary guidewire position by using an additional, larger guidewire for support to prevent dislodgment of the coronary guidewire.
