Safety and efficacy of 2.5-mm sirolimus-eluting stent implantation at lower deployment pressures in very small vessels (<2.5 mm).

Implantation of 2.5-mm SES in vessels with reference diameters less than 2.5 mm using lower deployment pressures and predilatation and postdilatation may lead to reduced risks of restenosis and MACE without an increased risk of stent thrombosis up to 1 year.
