About
Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS.
Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.
Full description
Study design:
Following pre-dilatation a BVS will be implanted and optical coherence tomography (OCT) will be performed in all patients. After OCT post-dilatation with non-compliant balloons might be performed if this is considered necessary by the treating interventionist. Final OCT will be performed in all patients. 1:1 Randomization of two strategies before the implantation of bioresorbable scaffolds:
OPN strategy (study group): pre-dilatation with OPN® NC (non-compliant) Super High Pressure PTCA (percutaneous transluminal coronary angioplasty) balloons standard strategy (control group): pre-dilatation with a standard (compliant) balloon
Enrolment:
Randomization of 50 patients
25 in the OPN strategy (study group) 25 in the standard strategy (control group)
