Initial clinical experience using an ostial stent positioning system (Ostial Pro) for the accurate placement of stents in the treatment of coronary aorto-ostial lesions.

Objective: To evaluate the safety and efficacy of a new nitinol stent positioning system to assist in the placement of aorto-ostial coronary stents.

Background: The stenting of aorto-ostial lesions is technically challenging.

Methods: We report the first clinical series using the Ostial Pro to assist in the precise placement of stents in coronary aorto-ostial lesions.
