The exception will be made in case of planned staged PCI procedures for other coronary lesions (study or non-study lesion) lesions, whereby the timeframe between procedures shall be determined by the clinical stability of the subject as assessed by the treating investigator. The subject must re-meet the inclusion criteria and be free from any exclusion criteria before enrolment.

• Subject has a known allergy to contrast agents or medications used to perform a coronary intervention that cannot be adequately pre-treated, including, but not limited to, sirolimus, paclitaxel, aspirin, heparin, clopidogrel bisulfate, ticlopidine, prasugrel, ticagrelor.
• History of stroke/TIA within 60 days before enrollment.
• Target lesion is located within a previous implanted stent.

Más betegség

• Chronic total occlusion (CTO) of the target lesion(s) or Thrombolysis In Myocardial Infarction (TIMI) flow < 2.
• Subject requires treatment of a coronary lesion(s) involving a bifurcation with significant ostial / proximal disease within 5mm of a side-branch greater than 2.0mm.
• Subject on dialysis, or acute kidney failure (as per physician judgment).
• Subject has a known allergy to urethane, nylon, or silicone.
• History of thrombolytic therapy within two weeks of enrollment.
• Subject is a recipient of a heart transplant.
• Subject has symptomatic active COVID-19 or is asymptomatic within the past 2 weeks of a positive COVID test.
  • Angiographic Exclusion Criteria:
• Subject has a planned intervention in the left-main plus two separate major epicardial territories (left-main plus 2 vessel diseases).

Laborértékek

• The subject has a known coagulopathy or has a bleeding diathesis, thrombocytopenia (with platelet counts less than 100,000/microliter) or platelets > 450,000/microliter, or international normalized ratio >1.5. Subjects on chronic oral anticoagulation medications will be excluded of the study.
• Known renal insufficiency, estimated glomerular filtration rate (eGFR) ≤30 mL/min, by institutional calculation.
• LVEF less than or equal to 35%.

Egyéb

• General Exclusion Criteria:
• Subject has current problems with substance abuse.
• Subject has a planned procedure that may cause non-compliance with the protocol.
• Target lesion(s) within native or synthetic vessel grafts.
• Presentation and index admission with STEMI. An exception to this exclusion is the treatment of the non-culprit target lesion with study device during a staged PCI procedure which can be either during the index STEMI admission (but not at the time of primary PCI) or electively at another date.
• Type 2 NSTEMI
• Presentation with ACS and ongoing chest pain and/or hemodynamic instability despite treatment of the culprit lesion
• Subject is confined to bed.
• Subject is unwilling/not able to return for angiographic catheterization at 6-month follow-up.
• Women who are pregnant, breast-feeding or intend to become pregnant.
• Subject has other medical, social, or psychological problems and is unwilling or unable to comply with procedures specified in the protocol or may have difficulty returning for follow-up visits as specified by the protocol.
• Cardiogenic shock (SBP <80mmHg requiring inotropes, IABP, or fluid support).
• Target vessel size <2.00 mm or >4.0 mm
• Target lesion in the left main stem.
• Target vessel with high thrombus burden.
• Aorto-ostial target RCA lesion (within < 10 mm of the aorta junction)
• Moderate-severe tortuous, calcified, or angulated coronary anatomy of the target vessel that, in the opinion of the Investigator, would result in suboptimal imaging or excessive risk of complication from placement of an IVUS catheter following Clinical Decision.
• The lesion is located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft.

• The subject is ≥18 years and <90 years old.
• Subject (or legal guardian) understands the trial requirements and the treatment procedures and provides written informed consent before any trial-specific tests or procedures are performed.
• Subject has been diagnosed with a symptomatic stable angina, or acute coronary syndrome.
• Life expectancy > 1 year.
• The subject is planned to undergo a percutaneous coronary intervention for a known lesion meeting the angiographic criteria set out below.
• Women of child-bearing potential must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure. Men with a female partner of childbearing potential must agree to use condoms plus an additional reliable contraceptive method within 12 months after the index procedure.
• The subject is able and willing to comply with all assessments in the study, including dual antiplatelet therapy (DAPT), ASA indefinitely, and P2Y12 inhibitor for a minimum of 6 months for stable angina subjects, and 12 months for unstable angina and NSTEMI subjects.
• The subject shall be under optimal medical therapy for ASCVD, which includes at a minimum high-intensity statin therapy. If statin intolerant, the subject should be treated with a PCSK9 inhibitor, ezetimibe or bempedoic acid.
  • Angiographic Inclusion Criteria:
• Target lesion is located within a de-novo lesion located in a native coronary artery with a reference vessel diameter between and including 2.0 mm and 4.0mm by visual estimate, with an in-segment length <=36mm. Target lesions must have a visually estimated stenosis of ≥50% and be <100% in symptomatic subjects prior to lesion pre-dilation.
• Subject has one or two lesions that meet inclusion and exclusion criteria individually that could be treated with a study device.
  • If multiple lesions are treated, only two may be treated with the investigational device.
  • If two lesions are treated with the investigational device, they must be in different vessels.
  • Non-target lesions (lesion to be treated with something other than the investigational device) may be treated at either baseline or staged PCI but never in the same vessel as the target lesion.
• Successful pre-dilation with semi and/or non-compliant balloon of the target lesion(s) (defined as no major flow-limiting dissections (Grade C or higher) and <30% residual stenosis of the target lesion by a visual estimate on angiography). Adjunctive pre-dilation therapies such as scoring balloon, cutting balloon, and IVL are allowed. Rotablator or similar rotational atherectomy devices are restricted per protocol.
