We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Devices - Carillon Mitral Contour System

Experimental: Implanted - Subjects successfully implanted with the Carillon Mitral Contour System


Treatment: Devices: Carillon Mitral Contour System
Eligible subjects will be implanted with the Carillon Device, utilizing the Carillon Mitral Contour System. The device is a permanent implant in the coronary sinus/great cardiac vein, designed to cinch the mitral annulus. The implant procedure is minimally invasive, conducted via catheter placement.

Eligibility
Key inclusion criteria
1. Moderate-to-severe non-primary Mitral Regurgitation (as assessed by qualitative,
semi-quantitative and/or quantitative echocardiographic assessment in the setting of
all of the following:

a. Severe left atrial (LA) dilatation as defined by at least two (2) of the following:
i. LA area = 41cm2 ii. Indexed LA volume > 48mL/m2 iii. LA diameter = 52 mm for men
and = 46 mm for women b. Preserved left ventricular contractility (Left Ventricular
Ejection Fraction =50% by Simpson's biplane technique) c. No more than mild left
ventricular dilatation as defined by: i. LV diastolic volume/BSA (mL/m2) <90 mL/m2 for
men and <71 mL/m2 for women ii. LV systolic volume/BSA (mL/m2) <39 mL/m2 for men and
<33 mL/m2 for women

2. New York Heart Association (NYHA) Class II, III or ambulatory IV heart failure

3. Stable heart failure medication regimen for at least 30 days prior to index procedure
including antihypertensives and/or diuretics to achieve controlled BP (< 140 mmHg
systolic) and adequate heart rate control (<100 bpm resting HR)

4. Patient deemed appropriate candidate for transcatheter mitral valve repair by the
local multidisciplinary heart team

5. Subject meets anatomic screening criteria as determined by angiographic screening at
the time of the index procedure to ensure that implant can be sized and placed in
accordance with the Instructions for Use

6. Female subjects of child-bearing potential must have a negative serum BHCG test

7. Age = 18 years old

8. The subject has read the informed consent, agrees to comply with the requirements, and
has signed the informed consent to participate in the study
Minimum age

bypass graft surgery, and/or unstable angina

2. Evidence of transient ischemic attack or stroke within three (3) months prior to
intervention

3. Percutaneous coronary intervention in the last 30 days

4. Subjects expected to require any cardiac surgery, including surgery for coronary
artery disease or for pulmonic, aortic, or tricuspid valve disease within one (1) year

5. Subjects expected to require any percutaneous coronary intervention within 30 days of
the index procedure.

6. Pre-existing device (e.g., pacing lead) in coronary sinus (CS) / great cardiac vein
(GCV), or anticipated need for cardiac resynchronization therapy (CRT) within twelve
(12) months

7. Presence of a coronary artery stent under the CS / GCV in the implant target zone

8. Presence of left atrial appendage (LAA) clot.

9. Presence of primary renal dysfunction or significantly compromised renal function as
reflected by a serum creatinine > 2.2 mg/dL (194.5 µmol/L) OR estimated Glomerular
Filtration Rate (eGFR) < 30 ml/min

10. Poorly controlled atrial fibrillation or flutter, with poor ventricular rate control
(> 100 bpm resting HR), or other poorly controlled symptomatic brady- or
tachy-arrhythmias

11. Uncontrolled hypertension (BP > 180 mmHg systolic and/or >105 mmHg diastolic) or
hypotension (BP < 90 mmHg systolic) at baseline

12. Presence of severe mitral annular calcification

13. Prior mitral valve surgery

14. Presence of a mechanical mitral heart valve, mitral bio-prosthetic valve or mitral
annuloplasty ring

15. Echocardiographic evidence of intracardiac mass, thrombus, or vegetation

16. Active endocarditis
