6. The AMADEUS ™ Trial  Study Design: Prospective, single-arm, 30 patient, Six month, multi-center trial  Inclusion Criteria Dilated Ischemic or Non-ischemic Cardiomyopathy (LVEDd > 55mm) NYHA Class II – IV FMR moderate to severe EF < 40% 6 MWT distance between 150m & 450m Stable on heart failure meds  Primary Endpoint: Thirty day rate of Major Adverse Events  Secondary Endpoints: Long-term safety; Hemodynamic and functional changes NYHA Class Exercise (6 minute walk test; Maximum Exercise Time) QOL (KCCQ) Change in MR 6

19. AMADEUS ™ Study Conclusions  AMADEUS ™ study achieved its safety endpoint with an acceptable MAE profile. 13% MAE rate @ 30 days was primarily non-device related.  At-risk coronary arteries were successfully managed in AMADEUS ™ with the CARILLON ™ “recapture” feature.  MR was reduced by 27% out to 6 months.  Statistically significant improvements in functional parameters out to 6 months (e.g., exercise, NYHA, QOL).  Short, simple procedure is important for this unstable HF patient population. 19
