This study showed that potential coronary artery compromise can be managed safely and effectively in all patients with 95% successfully implanted.

• 17 patients were implanted with the Carillon device in a prospective, single-center, non-randomized study.
• Patients experienced a mean one grade reduction of MR acutely (2.8 to 1.9, p<0.005) with an additional improvement at 3 months (1.5, p<0.005).
• In 41.2% of patients an acute reduction of coronary artery flow was detected intraoperatively and in all except one patient this could be easily managed such that the patients successfully received the implant.
