Key clinical point: “It may be prudent for less experienced operators to be cognizant of where they sit on the ‘learning curve’ and to pay particular attention to case selection,” investigators said.
Major finding: It took about 50 MitraClip cases for operator outcomes to start improving in a review of almost 14,923 cases in the United States, and outcomes were still improving at 200 cases.
Study details: Review of almost 15,000 MitraClip registry cases from Nov. 2013 to March 2018.
Disclosures: The work was supported by the ACC/STS TVT Registry. The lead and other investigators disclosed numerous ties to industry, including Abbott, the maker of MitraClip
