Detailed Study Protocol Parameters |
Study Objectives |
Objectives: to assess long term safety and effectiveness of the MitraClip device in a broad patient population and to study how prohibitive risk is interpreted in real-world use of the MitraClip device to ensure the device is used in appropriate circumstances.
Study design: a prospective, single-arm, multi-center, observational study of a minimum of 2,000 MitraClip patients consecutively entered into the TVT Registry. A new enrollment study.
|
Study Population |
Patients who have been determined to be at prohibitive risk for mitral valve surgery by a heart team, and in whom existing comorbidities would not preclude the expected benefit from reduction of the mitral regurgitation; patients treated in accordance with the MitraClip Clip Delivery System labeling, formal protocol- specific inclusion and exclusion criteria will not be used.
Cohort A: Patients treated per the MitraClip Clip Delivery System indication approved on October 24, 2013 will comprise Cohort A. Patients will be identified as Cohort A for analyses if the data collected on the eCRFs identify symptomatic DMR ≥3+ and at least one reason for prohibitive risk.
Cohort B: patients from the PAS 1 Device Registry who are not included in Cohort A.
|
Sample Size |
Subjects: 2,000 MitraClip patients consecutively entered into the TVT Registry.
Sites: This study will include all sites participating in the STS/ACCF TVT Registry and trained by Abbott Vascular to implant the MitraClip device.
A minimum of 2,000 patients will allow detection of low frequency safety events and provide improved precision for the rates of safety events that have previously been characterized.
|
Key Study Endpoints |
Primary Safety/Effectiveness Endpoints: The following endpoints will be reported through 1 year follow-up from data extracted from the TVT-R: ¿ All-cause mortality at 30 days and 1 year ¿ Stroke at 30 days and 1 year ¿ NYHA Functional Class at 30 days and 1 year ¿ Hospitalizations (All-cause and HF-related) at 1 year ¿ The echo parameters of MR severity, left ventricular end-diastolic volume (LVEDV) and Left Ventricular Internal Dimension-Diastole (LVIDd) at baseline, 30 days and 1 year in all patients and in the subset of patients who undergo mitral valve (MV) surgery within the first year
The following endpoints will be reported for years 2 - 5 post-implant by linking data extracted from the TVT Registry to the Center for Medicare and Medicaid Services (CMS) Claims database: ¿ All-cause mortality ¿ Stroke ¿ Hospitalizations (All-cause and HF-related) ¿ Surgical interventions Secondary Safety/Effectiveness Endpoints: Interpretation of the definition of prohibitive risk status in commercial use will also be reported on. Prohibitive risk status will be audited by a qualified MitraClip Registry Audit Committee Charter (MRAC) that meets quarterly. The composition and the schedule for auditing is described in the MRAC Charter document (received on June 10, 2014).
