Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS (Bioresorbable Vascular Scaffold).

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 ® 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)
