During coronary stent deployment there is a risk of compromising side branches, which can result in chest pain. Compromised side branches can be reopened by balloon angioplasty through the side of the stent. In a consecutive series of 10 patients with side‐branch compromise and chest pain, balloon angioplasty through the side of the stent resolved the ischemia in all cases. The stented segment showed no deterioration following side‐branch angioplasty. Six‐month follow‐up angiography showed a restenosis in the branch vessel of eight patients. The stented parent vessel restenosed in four patients. Therefore, side‐branch balloon angioplasty after coronary stenting for ongoing ischemia is technically feasible and immediately effective. Restenosis of the branch occurs in most cases. Cathet. Cardiovasc. Intervent. 46:421–424, 1999. © 1999 Wiley‐Liss, Inc.
