The TITAN study met its endpoint and showed the Carillon device can significantly and safely reduce FMR severity in heart failure patients, resulting in significant favorable reverse LV remodeling over 12 months and improved measures of clinical outcomes over 24 months.
The TITAN study was a prospective, non-randomized multi-center European study. The objective of the study was to determine if the Carillon device could safely and effectively reduce FMR and yield a durable long-term clinical benefit. Follow-up included typical clinical and echo assessments through 1 year and implanted patients had an additional clinical follow-up assessment at 2 years. The study was rigorously conducted with oversight by independent parties including an echo core lab, clinical events committee, and a data and safety monitoring board. Key inclusion criteria included MR grade 2+ to 4+, NYHA Class II-IV and LVEF <40%.
Of the 53 patients enrolled in the study, 36 underwent permanent implant of the device. In 17 patients, the device was recaptured (due to transient coronary impingement (n=8) or <1 grade FMR reduction (n=9). These non-implant patients were followed as a comparator group.
