Study summary

The COAPT Continued Access Study (CAS) is an extension of the COAPT RCT under the same IDE (G120024). COAPT CAS was a single-arm, prospective, multicenter continued access registry that enrolled heart failure patients with secondary mitral regurgitation who remained symptomatic despite optimal guideline-directed medical therapy (GDMT). The objective of the COAPT CAS is to continue the evaluation of safety and effectiveness of the MitraClip NT System under more "real world" conditions in patients who meet the COAPT inclusion/exclusion criteria and who have national Medicare coverage by the Centers for Medicare and Medicaid Services (CMS).
