Carillon® System

The Carillon Mitral Contour System® is a right-heart transcatheter mitral valve repair (TMVr) device designed to treat the main cause of functional mitral regurgitation (MR) in patients with MR grades 2+ to 4+.

MR in the context of heart failure is strongly associated with adverse patient outcomes,1 including one-year mortality rates up to 27% if left untreated.2

Designed to reshape the anatomy and improve function of the mitral apparatus from the coronary sinus, the Carillon System reduces regurgitant volume and induces favorable left ventricular remodeling without compromising the valve3, 4, 5 or future treatment options.6, 7

Using familiar catheter techniques, the device can be recaptured and retrieved prior to release.

Distal and proximal anchors, connected by a shaping ribbon, utilize the heart’s venous anatomy to cinch the mitral apparatus.

Simple Right-Heart Procedure

Easy to use with a short learning curve and no transseptal puncture


REDUCE FMR Clinical Trial

The Carillon System is the first TMVr therapy to demonstrate favorable left ventricular remodeling at one year and significant reduction in regurgitant volume in a blinded, randomized, sham-controlled trial (REDUCE FMR). The trial met its primary endpoint and results were consistent with the prior TITAN and TITAN II single-arm, multi-center studies.3, 4, 5

Key inclusion criteria

  • MR Grade* 2+ to 4+
  • NYHA Class II–IV
  • LVEF ≤50%

*assessed by site

Primary endpoint

Change in regurgitant volume at 1 year, as assessed by blinded echo core lab

120 patients in EU and Australia randomized 3:1

  • 87 randomized to treatment (Carillon System)
  • 33 randomized to sham control (guideline-directed medical therapy)

Significant Reduction in MR

Mean Change in RV at 1 Year (ITT)

Significant Favorable LV Remodeling

Mean Change in LVEDV at 1 Year (ITT)

Mean Change in LVESV at 1 Year (ITT)

Recurrent HF Hospitalizations and Total HF Admissions

Recurrent HF Hospitalizations (AT)

Rate of total HF Admissions (AT) (Per Patient Year)

AT = As-Treated Population (n=106)
ITT = Intention-to-Treat Population (n=120)

Positive Safety Profile

  • 98.9% freedom from device-related MAE through 1 year*
  • Low MAE rate at 30 days and 12 months in treatment-only group

*Events adjudicated by independent committee as related to device.

Additional Clinical Data

Increased mitral valve tenting is associated with an improvement in regurgitant volume with the Carillon System9
A retrospective analysis of 125 Carillon patients enrolled in the TITAN, TITAN II and REDUCE FMR clinical studies assessed the relationship between baseline tenting area and tenting height (coaptation distance) on percent regurgitant volume (RV) change and percent left ventricular end diastolic volume (LVEDV) change.

Quantitative analysis demonstrated acute effectiveness of the Carillon System in 83% of FMR patients8
A single-center study of 30 patients with moderate to severe FMR used transthoracic echocardiography (TTE) to measure regurgitant fraction (RF) by 2D-PISA method before and directly after Carillon implantation. Results showed a significant reduction in RF and acute MR benefit in 83% of patients.
