简要总结

The objective of this post market study is to examine the safety and performance of the Shockwave Coronary Intravascular Lithotripsy System for the treatment of narrowed coronary arteries before the doctor places a stent.

详细描述

The study will be conducted at 15 sites in Europe and up to 120 participants will be followed for 30 days post procedure.

Patients ≥18 years of age scheduled for stent procedure with evidence of significant calcified stenosis of left main, or left anterior descending, right coronary artery or left circumflex will be eligible to enroll in the study. The primary endpoint of the study will evaluate major adverse cardiac events post procedure including 1) cardiac related death, 2) heart attack, and 3) intervention to treat the coronary artery that was previously treated at the procedure visit.

  • Troponin must be less than or equal to the upper limit of lab normal value within 24 hours prior to the procedure OR if troponin is elevated, concomitant CK must be normal
  • The target vessel must have a TIMI flow 3 at baseline
  • Patients with significant (≥ 50% diameter stenosis) native coronary artery disease including stable or unstable angina and silent ischemia, suitable for PCI
  • Ability to tolerate dual antiplatelet agent (i.e. aspirin, clopidogrel, prasugrel, or ticagrelor) for 1 year and single antiplatelet therapy for life
  • Single lesion stenosis of protected LMCA, or LAD, RCA or LCX artery ≥50% in a reference vessel of 2.5 mm - 4.0 mm diameter and ≤ 32 mm length
  • Presence of calcification within the lesion on both sides of the vessel as assessed by angiography
  • Planned treatment of single lesion in one vessel
  • Ability to pass a 0.014" guide wire across the lesion
  • Patient, or authorized representative, signs a written Informed Consent form to participate in the study, prior to any study-mandated procedures
  • Patient is able and willing to comply with all assessments in the study

排除标准

  • Concomitant use of Atherectomy, Specialty balloon, or investigational coronary devices
  • Prior PCI procedure within the last 30 days of the index procedure
  • Patient has planned cardiovascular interventions within 30 days post index procedure

结局指标

主要结局

Number of Participants With In-hospital Major Adverse Cardiac Events (MACE)

时间窗: Post-procedure through hospital discharge

The primary endpoint is the frequency of in-hospital major adverse cardiac events (MACE). MACE is defined as the following: * Cardiac death * Myocardial Infarction - defined as a CK-MB level \> 3 times the upper limit of lab normal (ULN) value with or without new pathologic Q wave * TVR - defined as revascularization at the target vessel (inclusive of the target lesion) after the completion of the index procedure

次要结局

  • Number of Participants With Clinical Success(During procedure through hospital discharge)
  • Number of Participants With Angiographic Success(During procedure)
  • Number of Participants Which Experienced Cardiac Death(30 days post-procedure)
