In-hospital and late clinical outcomes of direct stenting strategy versus stenting after predilatation for the treatment of coronary artery lesions.

Background: Direct stenting without balloon dilatation may reduce procedural costs and duration, and hypothetically, the restenosis rate. This study was designed to compare the in-hospital and long-term outcomes of direct stenting (DS) versus stenting after predilatation (PS) in our routine clinical practice.

Methods: One thousand six hundred and three patients treated with stenting for single coronary lesions were enrolled into a prospective registry.
