The CARILLON\u00ae mitral contour system (Cardiac Dimensions, Kirkland, WA, USA), a mitral annuloplasty device delivered percutaneously to the coronary sinus, is designed to reduce the mitral annular dimension by virtue of the close anatomic relationship between the coronary sinus and the posterior mitral annulus. We performed a comprehensive individual patient data meta-analysis of all studies that used CARILLON\u00ae device vs. control that have measured mitral regurgitation severity, left ventricular (LV) remodelling, functional status, and heart failure-related outcomes in heart failure with reduced ejection fraction patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>The Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE were searched in July 2020. Primary outcomes of interest were measures of MR severity, LV remodelling, New York Heart Association functional class and heart failure-related outcomes [mortality and heart failure hospitalization (HFH) during follow up]. All data were received as individual patient and individual time point data-points. Mean differences and 95% confidence intervals (CIs) were calculated for continuous data using a fixed-effects model. Three studies (REDUCE FMR, TITAN and TITAN II) enrolling 209 participants were identified and included. Pooled analysis showed that, compared with control, CARILLON\u00ae device significantly improved both MR volume (mean difference MD -9.20, 95% C.I. \u221216.11 to \u22122.29 mL, P = 0.009) and MR grade (MD -1.12, 95% CI \u22121.36 to \u22120.88, P &amp;lt; 0.00001) and this was associated with a significant reduction in LA volume, MD \u22127.54 mL, 95% CI \u221214.90 to \u2212 0.18, P = 0.04. Significant LV reverse remodelling was also seen in terms of EDV (MD \u221216.53, 95% CI \u221228.61 to \u221244.4 mL, P = 0.007), and a trend in ESV (MD \u22128.68, 95% CI \u221218.69 to \u22121.34 mL, P = 0.09) but no significant effect on LVEF (MD 0.88, 95% CI \u22121.52% to 2.38%, P = 0.47), due presumably to the greater residual MR in the control patients falsely elevating the LVEF. In addition, the CARILLON\u00ae device significantly improved New York Heart Association functional Class (MD \u22120.22, 95% CI \u22120.24 to \u22120.16, P &amp;lt; 0.00001), associated with a lower rate of HFH compared with controls (45.3% vs. 64%, respectively, P = 0.04). As a sensitivity analysis we also restricted the analyses to those patients with Class 3+\/4+ MR at baseline. In this cohort, the echocardiographic results were similar, and the reduction in HFH rates was even more marked (43.9% vs. 82.9%, respectively, P = 0.04).<\/jats:p>\n                  <\/jats:sec>\n
