Brief summary

The primary objective of the MitraClip System Australia and New Zealand (ANZ) Clinical Trial is to gather real-world clinical and health-economic outcome data to support the long-term safety, efficacy and economic value of the MitraClip System in the continuum of therapies for treating MR. Specifically, the following clinical and economic data will be collected: New York Heart Association (NYHA) Functional Class, Six-Minute Walk Test (6MWT) distance, quality of life (QOL) information, echocardiographic measures of left ventricular size and function, and data associated with the index hospitalization, rehospitalizations, concomitant medications and discharge facility to support the MitraClip System economic analysis.

Detailed description

The MitraClip System ANZ Clinical Trial is a prospective, observational, single arm, multicenter trial to evaluate the MitraClip device for the treatment of mitral regurgitation (MR). Patients will be enrolled at up to 15 investigational sites throughout Australia and New Zealand. Up to 150 patients will be enrolled. Patients will be considered enrolled when local or general anesthesia is administered for the MitraClip procedure. Patients will be followed at discharge, 30 days, 6 months, 12 months and 24 months. Investigational sites will recruit consecutive patients who meet trial enrollment criteria. Until enrollment in the MitraClip System ANZ Clinical Trial is closed, all patients who undergo a procedure for placement of a MitraClip device at an investigational site should be enrolled in the MitraClip System ANZ Clinical Trial.

MeasureTime frameDescription
Percentage of Participants Experiencing Death (Kaplan-Meier Analysis)BaselineClinical Endpoint. * Cardiac death is defined as any death in which a cardiac cause cannot be excluded. (This includes but is not limited to acute myocardial infarction, cardiac perforation/pericardial tamponade, arrhythmia or conduction abnormality,cerebrovascular accident within 30 days of the procedure or cerebrovascular accident suspected of being related to the procedure, death due to complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery.) * Non-cardiac death is defined as a death not due to cardiac causes (as defined above).

Secondary

MeasureTime frameDescription
Number of Participants With Acute Procedural Success RateAt day 0 (on the day of index procedure)Defined as successful MitraClip implantation with resulting MR of 2+ or less.
Procedure TimeAt day 0 (on the day of index procedure)This is one of the Device and Procedure-Related Endpoints. Procedure Time is defined as the time elapsed from the start of the transseptal procedure to the time the Steerable Guide Catheter is removed.
Device TimeAt day 0 (on the day of index procedure)This is one of the Device and Procedure-Related Endpoints. Device Time is defined as the time the Steerable Guide Catheter is placed in the intra-atrial septum until the time the MitraClip Delivery System (CDS) is retracted into the Steerable Guide Catheter. Device Time is shorter in duration than Procedure Time because it does not include the time required to perform transseptal access into the left atrium.
Fluoroscopy DurationAt day 0 (on the day of index procedure)This is one of the Device and Procedure-Related Endpoints. Mean fluoroscopy duration during the MitraClip procedure.
Total Contrast VolumeAt day 0 (on the day of index procedure)This is one of the Device and Procedure-Related Endpoints.
Left Ventricle End Diastolic Volume (LVEDV)At Baseline and Discharge (≤7 days of index procedure)Left 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 Volume (LVESV)At Baseline and Discharge (≤7 days of index procedure)Left 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.
Left Ventricular Ejection Fraction (LVEF)At Baseline and Discharge (≤7 days of index procedure)Left ventricular ejection fraction is assessed by transthoracic echocardiography according to Simpson's rule (biplane method of disks).
Number of Participants With MR SeverityBaselineMitral regurgitation severity was determined based on the American Society of Echocardiography (ASE) Recommendations for Evaluation of The Severity of Native Valvular Regurgitation with Two-Dimensional and Doppler Echocardiography. MR severity was scored using the integrative method based on qualitative and quantitative echocardiographic parameters as described in the ASE guidelines.Site-assessed mitral regurgitation severity using echocardiography. MR severity was graded as follows: 0: None, 1+: Mild, 2+: Moderate, 3+: Moderate-to-Severe, 4+: Severe.
Left Ventricular Internal Diameter End Diastole (LVIDd)At Baseline and Discharge (≤7 days of index procedure)LVIDd is the measurements of the left ventricular internal dimension at end-diastole and normally corresponds to the largest cardiac dimension. LVIDd is measured by transthoracic echocardiography and the results are interpreted by the study's echocardiography core laboratory.
Left Ventricular Internal Diameter End Systole (LVIDs)At Baseline and Discharge (≤7 days of index procedure)LVIDs is the measurements of the left ventricular internal dimension at end-systole and normally corresponds to the smallest cardiac dimension. LVIDs is measured by transthoracic echocardiography and the results are interpreted by the study's echocardiography core laboratory.
Regurgitant VolumeAt Baseline and Discharge (≤7 days of index procedure)Regurgitant volume as determined by the core echo laboratory. In the presence of regurgitation of one valve, without any intracardiac shunt, the flow through the affected valve is larger than through other competent valves. The difference between the two represents the regurgitant volume.
Regurgitant FractionAt Baseline and Discharge (≤7 days of index procedure)Regurgitant fraction as determined by the core echo laboratory. Regurgitant fraction is defined as the regurgitant volume divided by the forward stroke volume through the regurgitant valve.
Mitral Valve Area (MVA) by Pressure Half-time (PHT)At Baseline and Discharge (≤7 days of index procedure)Measure of the area of the mitral valve orifice using transthoracic echocardiography. The pressure half time method is used to assess the presence and severity of mitral stenosis. Results are interpreted by the study's echocardiography core laboratory.
Number of Participants With 0, 1, 2, and 3 MitraClip Devices ImplantedDay 0 (On the day of procedure)This is one of the Device and Procedure-Related Endpoints. Implant Rate is defined as the rate of successful delivery and deployment of MitraClip device implant(s) with echocardiographic evidence of leaflet approximation and retrieval of the delivery catheter.
Left Atrial VolumeAt Baseline and Discharge (≤7 days of index procedure)Left atrial volume is assessed by echocardiography. Using the single plane method of disks, the left atrial volume is derived by planimetry in the 4-chamber view at end-systole.
Six Minute Walking DistanceBaselineThe six-minute walk test (6MWT) measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface. It is a measure of a patient's exercise capacity.
Percentage of Participants With New York Heart Association (NYHA) ClassBaseline* 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.

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.

Time frame: 30 days

Population: A total of 69 patients were included in analysis population because 6 patients had lost-to-follow up at 30 days and 3 patients did not have a NYHA functional class assessment.
