Short- and long-term outcome of balloon angioplasty for compromised side branches after intracoronary stent deployment.
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.
