NCT03988166

Brief Summary

The objective of this study is to evaluate angiographic confirmation of placement of any guidewire beyond the CTO, in the true vessel lumen, in patients undergoing CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Procedure Success

    Defined as angiographic visualization of any guidewire in a position either distal or proximal to the occlusion depending on the route of access and the absence of in-hospital major adverse cardiac events (MACE). • MACE defined as any serious adverse experience that includes cardiac death, target lesion revascularization, or post-procedural myocardial infarction (MI) (Q-wave or non-Q-wave, with creatine kinase (CK) with Muscle (M)-Brain (B) subunits \> 3 ULN).

    Through Discharge up to 24 hours post-procedure

Secondary Outcomes (5)

  • Number of Participants With Successful Recanalization.

    Through Procedure, up to 4 hours

  • Number of Participants With In-hospital MACE.

    Through Discharge up to 24 hours

  • Number of Participants With Clinically Significant Perforation.

    Through Procedure up to 4 hours

  • Number of Participants With Procedural Success According to Crossing Technique.

    Through Procedure up to 4 hours post-procedure

  • Number of Participants With Technical Success.

    Through Procedure up to 4 hours post-procedure

Study Arms (1)

Chronic Total Occlusion Percutaneous Coronary Intervention

OTHER

CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.

Procedure: Chronic Total Occlusion RevascularizationDevice: GuideLiner® V3 catheter, TrapLiner® catheter, Turnpike® catheter

Interventions

Teleflex's series of study guidewires and catheters will be used to facilitate the safe and effective crossing of de novo CTOs and placement of conventional guidewires beyond the lesion via either a true lumen or subintimal pathway.

Chronic Total Occlusion Percutaneous Coronary Intervention

GuideLiner® V3 catheter, TrapLiner® catheter, Turnpike® catheter

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • At least 18 years of age at the time of consent
  • Experiencing clinical symptoms considered suggestive of ischemic heart disease (e.g., chest pain or discomfort, heart failure) or has evidence of myocardial ischemia (e.g., abnormal functional study) attributed to the CTO target vessel and is scheduled for clinically indicated percutaneous revascularization
  • Participant is eligible and consents to undergo PCI procedure
  • Acceptable candidate for percutaneous transluminal coronary angioplasty (PTCA), stenting, and emergency coronary artery bypass grafting (CABG)
  • Willing and able to sign a study Informed Consent Form (ICF) approved by a local or central Institutional Review Board (IRB)
  • Female participants of childbearing potential must have a negative pregnancy test per standard of care for PCI and be practicing contraception
  • A minimum of one de novo lesion with at least one target segment in a native coronary vessel meeting the definition of CTO (any non-acute total coronary occlusion fulfilling the angiographic characteristics consistent with high-grade native coronary stenosis (Thrombolysis in Myocardial Infarction (TIMI) score of 0 or 1) and estimated to be in duration of ≥ 3 months by clinical history and/or comparison with antecedent angiogram or electrocardiogram)

You may not qualify if:

  • History of allergy to iodinated contrast that cannot be effectively managed medically
  • Evidence of acute myocardial infarction (MI) within 72 hours prior to the intended treatment defined as creatine kinase-muscle brain subunits (CK-MB) greater than 3 times the upper limit of normal (ULN)
  • Previous coronary interventional procedure of any kind within 30 days prior to the procedure
  • Any contraindication to cardiac catheterization or to any of the standard concomitant therapies used during routine cardiac catheterization and PCI (e.g., aspirin, clopidogrel, unfractionated heparin)
  • Target lesion requires treatment with another device, after successful crossing with a study device, other than PTCA devices prior to stent placement
  • Atherectomy procedure is planned for the target lesion
  • Known history of clinically significant abnormal laboratory findings ≤ 14 days prior to enrollment, including:
  • Neutropenia (\<1000 neutrophils/mm\^3)
  • Thrombocytopenia (\<100,000 platelets/mm\^3)
  • Aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase, or bilirubin \> 1.5 × ULN
  • Serum creatinine \>2.0 mg/dL
  • Evidence of current clinical instability including the following:
  • Sustained systolic blood pressure \<100 mmHg or cardiogenic shock
  • Acute pulmonary edema or severe congestive heart failure (CHF). Severe CHF is defined as New York Heart Association (NYHA) Class IV
  • Suspected acute myocarditis, pericarditis, endocarditis, or cardiac tamponade
  • +15 more criteria
