The TITAN II study achieved its endpoint and showed significant improvements in echo parameters and patient function.
TITAN II was a single-arm study designed to assess the safety and efficacy of an updated version of the Carillon system. Inclusion and exclusion criteria were similar to those in TITAN. Patients had symptomatic congestive heart failure (NYHA class ≥2), MR grade 2+ to 4+, a dilated LV (LVEDD >55 mm) and an ejection fraction <40%. Quantitative assessments of MR were performed by an independent core echo laboratory, and MAE were reviewed by an independent data and safety monitoring board. In total, 36 patients were enrolled; 30 received a permanent implant.
