Clinical Trial 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.

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.

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.	Baseline

Secondary	Change in Minnesota Living With Heart Failure (MLWHF) Quality of Life (QOL) Score From Baseline to 30 Days	The Minnesota Living with Heart Failure Questionnaire(MLHFQ) is comprised of 21 questions.The response for each question ranges from 0(no affect on the patient's living) to 5(affected the patient's life very much during the past month).The total score for the 21 items can range from 0-105.A lower&higher MLHFQ score indicates less effect of heart failure&the worse impact of heart failure on a patient's QOL,respectively.Although the MLHFQ incorporates relevant aspects of the key dimensions of QOL (physical and emotional),the questionnaire was not designed to measure any particular dimension separately.The total score should be taken as the best measure of how heart failure and treatments impact QOL.; The total score is the sum of a)the physical dimension,measured using 8 questions (possible subscale score range 0-40) b)the emotional dimension,measured using 5 questions(possible subscale score from 0-25)&c) other factors,measured using 8 questions (possible subscale score from 0-40).	30 days
