• Patient-related:

‣ Patient must be ≥ 18 years of age

⁃ Patient is able to verbally confirm understanding of the study aim, risks, benefits, and treatment alternatives of receiving DCB or DES and he/she or his/her legally authorized representative provides written informed consent prior to any study-related procedure

⁃ (i) Clinical evidence of angina, and/or (ii) an abnormal functional study demonstrating myocardial ischemia due to the target lesion(s), or (iii) acute coronary syndrome \[unstable angina or non-ST-elevation myocardial infarction (NSTEMI) or uneventful STEMI (≥ 48 hours after primary PCI and no sign of thrombus in lesion(s) to treat)\]

⁃ Patient with lesions suitable for PCI with a DCB (and/or DES) according to the Instructions for Use

⁃ Patient is able to comply with the study protocol and agrees to undergo the clinical follow-up of 30 days, 6 months, 12 months, 24 months, and 36 months

• Lesion-related:

‣ Presence of significant de novo large vessel coronary artery disease (reference vessel diameter ≥3.0 mm by visual estimation) with either ≥ 70% diameter stenosis or intermediate ≥ 50% to \<70% diameter stenosis with abnormal functional test or symptom of ischemia

⁃ Successful lesion preparation. For randomisation, the lesion must satisfy the following criteria after optimal balloon angioplasty: no flow-limiting dissection (TIMI=3), and residual stenosis is ≤ 30%

• Multivessel disease with two or more vessels showing diameter stenosis of 50% or more is not an exclusion as long as it fulfills all study's eligibility criteria.

• In diffuse lesion, inclusion is possible if the proximal reference vessel diameter is 3.0 mm or more.
