Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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.

6 Months

Eligibility
Key inclusion criteria

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

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
