This analysis showed that Carillon addresses FMR and, in as little as one-month, successful implantation results in left ventricular reverse remodelling and increased systolic performance. Mitral tenting area is an important baseline parameter in predicting treatment efficacy with Carillon.

• 35 patients were enrolled and 22 were successfully implanted with the Carillon device. Some patients were not implanted due to coronary sinus size (n=3), impaired access (n=2), compromised coronary flow (n=4), or insufficient mitral regurgitation reduction (n=4).
• At one-month follow-up, statistically significant reductions in the following parameters were observed: anteroposterior (AP) diameter, regurgitant volume (RV), vena contracta (VC), effective regurgitant orifice area (EROA), proximal isovelocity surface area (PISA), mitral tenting area, mitral tethering, and mean diastolic interpapillary distance.
• Patients with increased left atrial diameters saw greater improvement in ejection fraction, following implantation.
