Multi-center Prospective Study to Evaluate Outcomes of the Moderate to Severely Calcified Coronary Lesions (MACE) (MACE)

The objective of this study is to assess the current standard of care treatment outcome in none/mild, moderate and severely calcified coronary lesions using:

• A composite of MACE at 30-day and one (1) year post procedure, and
• Procedural and lesion success

Study Overview

• Status: Completed
• Conditions: Coronary Artery Disease
• Intervention / Treatment: Device: Percutaneous Coronary Intervention

Detailed Description

This prospective, non-randomized, multi-center study includes subjects who meet all of the inclusion and none of the exclusion criteria and sign the ICF. This study may treat up to approximately 500 subjects at up to 50 active sites in the U.S. Subjects may be followed up to three (3) years. Subjects will be stratified into one (1) of three (3) arms based on the degree of calcification in the coronary lesion as defined by this protocol. The duration of the study is expected to be approximately four (4) years.

Inclusion Criteria:

1. Subjects must be at least 18 years of age.
2. Subjects must be scheduled for percutaneous coronary revascularization involving stent deployment in de novo coronary lesions. Percutaneous coronary revascularization is defined as treatment with commercially available devices that may include but not limited to balloon angioplasty, cutting balloon, rotablation, etc. followed by the stent placement.
3. Subjects CK-MB must be less than or equal to the upper limit of lab normal value within eight (8) hours prior to procedure. If CK-MB results are not yet available prior to initiating procedure, subjects Troponin I or Troponin T must be less than or equal to the upper limit of lab normal value within eight (8) hours prior to the procedure.
4. The target lesion must be a de novo coronary lesion that has not been previously treated with any interventional procedure.

5. The target vessel must be a native coronary artery with:

   1. A stenosis ≥ 70% and < 100%, or
   2. A stenosis ≥ 50% < 70% with evidence of clinical ischemia
6. The target vessel reference diameter must be ≥ 2.5mm and ≤ 4.0 mm.
7. The lesion length must not exceed 40 mm.
8. The target vessel must have a Thrombolysis In Myocardial Infarction (TIMI) flow three (3) at baseline.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MACE at 30 Days	A Kaplan-Meier analysis was performed to determine the percent probability that a study participant experienced a major adverse cardiac event through 30 days. 30-day MACE is composed of: Cardiac death; Myocardial Infarction (MI) - defined as a Creatine Kinase Myocardial-Band Isoenzyme (CK-MB) level greater than three (3) times the Upper Limit of Lab Normal (ULN) value with or without new pathologic Q wave; Target Vessel Revascularization (TVR) - defined as a revascularization at the target vessel (inclusive of the target lesion) after the completion of the index procedure	30 days post procedure

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MACE at One (1) Year	A Kaplan-Meier analysis was performed to determine the percent probability that a study participant experienced a major adverse cardiac event through 1 year. 1-year MACE is composed of: Cardiac death; Myocardial Infarction (MI) - defined as a Creatine Kinase Myocardial-Band Isoenzyme (CK-MB) level greater than three (3) times the Upper Limit of Lab Normal (ULN) value with or without new pathologic Q wave; Target Vessel Revascularization (TVR) - defined as a revascularization at the target vessel (inclusive of the target lesion) after the completion of the index procedure	One (1) year post procedure
Procedural Success	Procedural success is defined as success in facilitating stent delivery with a residual stenosis of <50% and without the occurrence of an in-hospital MACE.	Participants were followed from baseline procedure through hospital discharge, an expected average of 24 hours
Lesion Success	Lesion success is defined as success in facilitating stent delivery with a post-procedural result of <50% residual stenosis for a given lesion treated during the procedure without severe angiographic complications.	During the procedure
