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.
Interventions
Percutaneous mitral valve repair using MitraClip implant.

| Device Time | At 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.

| Percentage of Participants With New York Heart Association (NYHA) Class | Baseline | * 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. |

Percentage of Participants Experiencing Freedom From Death and Congestive Heart Failure (Kaplan-Meier Curve Analysis)
Death: Defined as all causes of death for the primary safety Major Adverse Event (MAE) Endpoint. Death is further divided into 2 categories: A. Cardiac death is defined as death due to any of the following: * Acute myocardial infarction * Cardiac perforation/pericardial tamponade * Arrhythmia or conduction abnormality * Stroke within 30 days of the procedure or stroke suspected of being related to the procedure * Death due to any complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery * Any death for which a cardiac cause cannot be excluded. B. Non-cardiac death is defined as a death not due to cardiac causes (as defined above). Congestive Heart Failure (CHF): Defined as a documented diagnosis of CHF on the hospital admission report or discharge summary.
Time frame: 6 months
Population: At 6 months, 55 patients were considered at risk because 17 had been censored, and 6 patients experienced an event (i.e. death or CHF event).

Percentage of Participants With New York Heart Association (NYHA) Class
* 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.
Time frame: 12 months
Population: NYHA functional class assessment is available for 40 patients at 12 months.Five patients died prior to the 12-month visit,1 patient missed the 12-month visit, 3 patients did not have a NYHA functional class assessment and finally 29 patients 12-month visits were either expected or not due at the time that the ANZ trial was terminated.
