Detailed description

Phase I evaluation of the safety and effectiveness of an endovascular approach to the repair of mitral valve regurgitation using the Evalve Cardiovascular Valve Repair System. The study is a prospective, multi-center, Phase I study of the Evalve Cardiovascular Valve Repair System (CVRS) in the treatment of mitral valve regurgitation. A minimum of 20 patients will be enrolled (an additional maximum of 12 roll in-patients, a maximum of 2 per site, may be enrolled and analyzed separately). Patients will undergo 30-day, 6 month and 12 month clinical follow-up. Up to 12 clinical sites throughout the US may participate. The primary endpoint is acute safety at thirty days, with a secondary efficacy endpoint of reduction of MR.

Primary

MeasureTime frameDescription
Mitral Regurgitation SeverityAt baselineAll patients were screened and determined eligible by Investigators who utilized transthoracic echocardiograms (TTE) to determine MR severity grades based on the American Society of Echocardiology recommendations for the determination of native valvular regurgitation. MR severity was assessed by an independent Echocardiography Core Laboratory (ECL).
Major Adverse Events (MAE)Through 30 daysDefined in the Protocol as a combined clinical endpoint of death, myocardial infarction, cardiac tamponade, cardiac surgery for failed MitraClip device, single leaflet device attachment, stroke and septicemia.

Intra-procedural Major Adverse EventsAt day 0 (on the day of index procedure)Significant intra-procedural Major adverse events are defined as Major Adverse Events that occurred on the day of the procedure
Post-procedure Intensive Care Unit (ICU)/Critical Care Unit (CCU)/Post-anesthesia Care Unit (PACU) DurationPost index procedure within 30 days
Post-procedure Hospital StayPost-index procedure until hospital discharge (1 to 19 days)
Second Intervention to Place a Second MitraClip DevicePost index procedure through 5 years
MitraClip Device Embolizations and Single Leaflet Device AttachmentPost index procedure through 5 yearsMitraClip device embolizations means the detachment from both mitral leaflets. Single Leaflet Device Attachment (SLDA) is defined as the attachment of a single leaflet to the MitraClip device.
Mitral Valve Surgery Post-MitraClip Device Implant Procedure (Kaplan-Meier Freedom From Mitral Valve Surgery)At baselineFreedom from mitral valve surgery required to treat mitral regurgitation and/or mitral stenosis and/or for Cardiac Surgery for Failed Clip following the MitraClip device procedure.
Death (Kaplan-Meier Freedom From Death)Within 30 days of the procedure
Procedure TimeAt day 0 (on the day of index procedure)Procedure Time, defined as the time of start of the transseptal procedure to the time the Steerable Guide Catheter (SOC) is removed, averaged 255 minutes, or just over 4 hours. The reported Procedure Time includes the time required to collect Protocol required hemodynamic data pre- and post-implantation of the MitraClip device.
Other Secondary Safety EventsThrough 30 daysOther safety event includes Endocarditis, MitraClip DeviceThrombosis, Hemolysis, Mitral Valve Injury (major).
Left Ventricular End Diastolic VolumeBaselineLeft Ventricular end-diastolic volume (LVEDV) as determined by the core echo laboratory. Left Ventricular end-diastolic volume (LVEDV) measured using 2-dimensional echocardiography. The endocardium is traced at end-diastole (frame before mitral valve closure or maximum cavity dimension) in the 2- and 4-chamber views to calculate volumes.
Left Ventricular End Systolic VolumeBaselineLeft Ventricular end-systolic volume (LVESV) as determined by the core echo laboratory. Left Ventricular end-systolic volume (LVESV) measured using 2-dimensional echocardiography. The endocardium is traced at end-systole (frame prior to mitral valve opening or the minimum cavity area) in the 2- and 4-chamber views to calculate volumes.
Mitral Valve Area - Single OrificeBaselineMitral valve area measured by planimetry. Using a cineloop acquired at the mitral valve leaflet tips, the point in diastole corresponding to the maximal opening is identified. The area pre-device as well as post-device are planimetered. Post-device, the mitral valve orifice area is the sum of the area of each of the two orifices.
Mitral Valve Area (MVA) by Pressure Half-TimeBaselineThe pressure half time (PHT) measurement for assessing the severity of mitral stenosis is a widely accepted echocardiographic method. The decline of the velocity of diastolic transmitral blood flow is inversely proportional to mitral valve area (MVA), and MVA is derived using the empirical formula: MVA (cm\^2) = 220/PHT PHT is calculated automatically by tracing the deceleration slope of the E-wave of transmitral flow, obtained with continuous wave Doppler echocardiography.
Mitral Valve GradientBaselineDefined as the mean and peak pressure gradients across the mitral valve as measured by echocardiography.
Cardiac OutputBaselineCardiac output as measured by core lab echocardiography. Cardiac output is the product of forward stroke volume and heart rate.
Cardiac IndexBaselineCardiac index is defined as cardiac output divided by body surface area. Cardiac Index is measured by core lab echocardiography.
New York Heart Association (NYHA) Functional ClassBaselineDefined as assessment of NYHA functional class status at follow-up compared to baseline NYHA functional class status. Class I: Patients with cardiac disease but without resulting limitations of physical activity. Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain. Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain. Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.
Major Vascular and Bleeding ComplicationsThrough 30 daysMajor bleeding complications is defined as transfusion of \>=2 units of blood due to bleeding related to the index procedure
Device TimeAt day 0 (on the day of index procedure)Device Time, defined as the time of insertion of the Steerable Guide Catheter (SGC) to the time the MitraClip Delivery Catheter is retracted into the SGC.

Mitral Valve Area (MVA) by Pressure Half-Time

The pressure half time (PHT) measurement for assessing the severity of mitral stenosis is a widely accepted echocardiographic method. The decline of the velocity of diastolic transmitral blood flow is inversely proportional to mitral valve area (MVA), and MVA is derived using the empirical formula: MVA (cm\^2) = 220/PHT PHT is calculated automatically by tracing the deceleration slope of the E-wave of transmitral flow, obtained with continuous wave Doppler echocardiography.
