Study Details

Study Description

Brief Summary

The purpose of this study is to collect long term data of the Neovasc Reducer System in subjects with refractory angina pectoris.

Condition or Disease Intervention/Treatment Phase
  • Device: Neovasc Reducer System

Detailed Description

This study is a multicenter, multi-country three-arm prospective and retrospective investigation in up to 400 subjects conducted at a maximum of 40 investigational centers. Arm 1 will include eligible prospective subjects. Arm 2 will include subjects who were previously enrolled and treated with the Reducer during the COSIRA (Coronary Sinus Reducer for Treatment of Refractory Angina) study. Arm 3 will include subjects who received a Reducer under CE Mark (unrelated to the COSIRA study).

    Other Names:
  • Reducer
  • Outcome Measures

    Primary Outcome Measures

    1. Reduction in Canadian Cardiovascular Society (CCS) Grade [6 Months]

      The percentage of subjects who experience improvement in their angina symptoms defined as a reduction in CCS grade, at 6 months as compared to baseline

    2. Rate of Occurrence of Device and/or Procedure Related Peri-Procedural Serious Adverse Events (SAE)s [30 days post implant]

      The rate of occurrence of device and / or procedure-related periprocedural SAEs defined as a composite of death, Myocardial Infarction (MI), cardiac tamponade, clinically-driven re-dilation of a Reducer, life-threatening arrhythmias (Ventricular Tachycardia (VT) or Ventricular Fibrillation (VF)), and respiratory failure through 30 days post-implant

    3. Occurrence of Major Adverse Cardiac Events (MACE) [30 days post implant]

      Major Adverse Cardiac Events (MACE): a composite of cardiac death, major stroke, and MI through 30-days post-implant

    Secondary Outcome Measures

    1. Reduction in Canadian Cardiovascular Society (CCS) Grade [12 months and annually through 5 years]

      The percentage of subjects who experience improvement in their angina symptoms defined as a reduction in CCS grade at 12 months and annually through 5 years post implant as compared to baseline

    2. Occurrence of Major Adverse Cardiac Events (MACE) [6 months, 12 months, and annually through 5 years]

      Major Adverse Cardiac Events (MACE): a composite of cardiac death, major stroke, and MI at 6 months, 12 months and annually through 5 years post implant

    Other Outcome Measures

    1. Change in Exercise Tolerance Test (ETT) Parameters [6 and 12 months]

      The change in ETT parameters at 6 and 12 months post implant as compared to baseline: Total exercise duration (min), Time to 1mm ST-Segment Depression (min), METs, Double Product by ETT

    2. Improvement in Quality of Life (QoL [6 months, 12 months, and annually through 5 years]

      Improvement in QoL scores at 6 months, 12 months and annually through 5 years post implant as compared to baseline

    3. Reduction in Emergency Department Visits [12 months]

      Reduction in documented Emergency Department visits due to angina episodes at 12 months post implant as compared to 12 months prior to implantation of the Reducer

    4. Reduction in Angina Medication [6 months, 12 months, and annually through 5 years]

      Reduction in angina medication use at 6 months, 12 months and annually through 5 years post implant as compared to baseline
