It is possible to implant the Carillon device prior to a CRT device in HF patients with low ejection fraction, wide QRS and FMR.

• Three patients meeting current guidelines for cardiac resynchronization therapy (CRT) included in the AMADEUS trial underwent CRT implantation 7-8 months after implantation of a mitral valve annuloplasty device.
• Access to the coronary sinus and placement of the left ventricular lead into a posterolateral cardiac vein was not at all compromised by the mitral valve annuloplasty device in any patient.
