Perfection of precise ostial stent placement.
Ostial lesions, including aorta-ostial lesions and Medina 001 bifurcation lesions, are known to create difficulty in precise stent placement. There are many techniques used to help in precise ostial stent placement; these include using multiple angiographic views to assist in placement, the use of the Ostial Pro device, the aorta flowing wire technique, Szabo (anchor-wire) techniques, the T-stent and small protrusion (TAP) technique, the cross-over 1-stent technique, and new dedicated ostial stents. In this review, we summarize these different techniques and show that there is no universal technique that allows for perfect ostial stent placement.
