This study was performed to assess the immediate and long‐term patency of stent‐associated side branches (SB) according to the types of stent. A total of 314 patients with 332 lesions (CrossFlex stent 86, NIR 100, GFX 146) had 365 SB (>1 mm) covered by coronary stents. Side branch occlusion (SBO) occurred in 7.7% of CrossFlex stent, in 10.5% of NIR stent and in 8.8% of GFX stent ( P = NS). SBO primarily occurred in SB with ostial disease, and the presence of SB ostial disease was the only independent predictors of SBO after stenting (OR 22.1, 95% CI 9.47–51.49, P < 0.001). At 6 months follow‐up, 11 of 31 SBO regained the patency, but the remaining SB had persistent SBO. Delayed SBO occurred in 8 SB, being associated with the presence of SB ostial disease and in‐stent restenosis. In conclusions, SBO was not associated with the types of stent design, but with the SB lesion morphology. Cathet Cardiovasc Intervent 2001;52:18–23. © 2001 Wiley‐Liss, Inc.
