Shockwave Coronary Lithoplasty® Study (Disrupt CAD II)

Not Applicable

Completed

• Conditions: Coronary Artery Disease
• Interventions: Device: IVL Coronary Lithotripsy System

• Registration Number: NCT03328949
• Lead Sponsor: Shockwave Medical, Inc.

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
IVL Coronary Lithotripsy System	IVL Coronary Lithotripsy System	All enrolled patients will receive treatment from the IVL coronary lithotripsy system prior to coronary stent placement.

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Clinical Success	During procedure through hospital discharge	Performance will be assessed by the ability of the Lithotripsy System to produce acceptable residual stenosis (\<50%) after stenting with no evidence of in-hospital MACE. Each patient that achieves both of these requirements will be considered a "clinical success", and the rate of clinical success among subjects will be evaluated.
Number of Participants With Angiographic Success	During procedure	Angiographic success defined as success in facilitating stent delivery with \<50% residual stenosis and without serious angiographic complications. Serious angiographic complications defined as severe dissection (Type D to F), perforation, abrupt closure, and persistent slow flow or persistent no reflow.
Number of Participants Which Experienced Cardiac Death	30 days post-procedure	Number of patients who experienced a cardiac death at 30 days post-procedure.
