Dear Author,
you described a rare case of immediate clip detachment from one of the leaflet. Usually this happens in the first three months. It is difficult that this can happen in the lab, since, in my opinion, this was a simple case, not degenerative with favorable anatomy and, maybe, you did not pay enought attention to leaflet insertion. Secondly convertion to surgery is debatable. A second attempt with multiple clip was possible since the patient was stable.
Finally the article is not so well written.
