TriClipTM Device
DeviceTranscatheter TriClip placement in the tricuspid valve to repair the valve and correct regurgitation
NCT Number: NCT03904147
The primary objective of this trial is to demonstrate the safety and effectiveness of the TriClip device in improving clinical outcomes in symptomatic patients with severe tricuspid regurgitation (TR), who are at intermediate or greater estimated risk for mortality or morbidity with tricuspid valve surgery. This randomized controlled trial will compare the investigational device (TriClip device) to Control (Medical Therapy).

Transcatheter TriClip placement in the tricuspid valve to repair the valve and correct regurgitation
Time frame: 12 Months
Analysis of hierarchical composite of all-cause death or tricuspid valve surgery, heart failure hospitalizations, and KCCQ improvement of at least 15 points was performed in ITT population using Finkelstein-Schoenfeld method.
A win ratio was also calculated to descriptively quantify the magnitude of treatment benefits. The win ratio is calculated as the ratio of the number of wins in Device versus Control patients. The primary analysis population consisted of 175 Device patients and 175 Control patients, resulting in 30,625 Device-Control patient pairs (i.e., 175 × 175).
Time frame: 12 months
This outcome will be assessed as the percentage of subjects meeting the definition of the endpoint.
Time frame: 30 Days
Freedom from major adverse events (MAE) was assessed in the Attempted Procedure population (n=172). MAEs included cardiovascular mortality, new onset renal failure, endocarditis requiring surgery, and non-elective cardiovascular surgery for TriClip device-related AE post-index procedure.
Time frame: 12 months minus baseline
The mean change in KCCQ score between 12 months and baseline in the Device and Control groups will be compared, while adjusting for the baseline KCCQ score. The primary analysis for this endpoint imputed a KCCQ score of 0 at 12-month visit for all subjects who experienced a heart failure related cardiovascular death or received tricuspid valve surgery prior to completing 12-month follow-up. All KCCQ scores are scaled from 0 (worst) to 100 (best possible status), where the higher score reflects a better health status.
Time frame: 30 Days
The percentage of subjects with tricuspid regurgitation reduced to moderate or less at 30-day visit in the Device Group will be compared with that in the Control Group. Tricuspid regurgitation severity will be graded on a 5-point scale: trace/mild, moderate, severe (severe 3), massive (severe 4), and torrential (severe 5), which has frequently been used in recent interventional tricuspid studies to categorize tricuspid regurgitation severity. This grading system follows the 2017 ASE guidelines (Zoghbi WA, Adams D, Bonow RO et al. Recommendations for Noninvasive Evaluation of Native Valvular Regurgitation: A Report from the American Society of Echocardiography Developed in Collaboration with the Society for Cardiovascular Magnetic Resonance. J Am Soc Echocardiogr 2017;30:303-371.), and further stratifies the traditional "severe" category into severe (Severe 3), massive (Severe 4), and torrential (Severe 5).
Time frame: 12 Months
The primary analysis for this endpoint imputed a 6MWT distance of 0 meters for all subjects who experienced a heart failure related cardiovascular death or received tricuspid valve surgery prior to completing 12-month follow-up. Subjects who were unable to exercise due to cardiac reasons were also assigned a 6MWT distance of 0 meters at 12-month follow-up. Other subjects with missing 6MWT distance at either baseline or 12-month follow-up were excluded from the analysis.
Time frame: 30 days
Time frame: 30 days
Freedom from MAE occurring after procedure attempt (femoral vein puncture) at 30 days. Components of MAE consist of Cardiovascular Mortality, New Onset Renal Failure, Endocarditis Requiring Surgery, and Non-Elective Cardiovascular Surgery for TriClip device-related AE post-index procedure.
Time frame: 12 months
This analysis imputed a 6MWT distance of 0 meters for all subjects who were unable to exercise due to cardiac reasons. However, there were no subjects unable to exercise due to cardiac reasons and therefore no imputation was performed. Subjects with missing 6MWT distance at either baseline or 12-month follow-up were excluded from the analysis.
Time frame: 24 months
H0: HR(24M)>1; H1: HR(24M)≤1
Time frame: 24 months
H0: Survival curves of the two groups through 24 months are the same. H1: Survival curves of the two groups through 24 months are different.
