While some reports show the utility of repeat clipping for recurrent MR, the results are unsatisfactory. We describe a patient who underwent repeat clipping for MR that recurred from both sides of the original clip.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>An 89-year-old male was admitted to our hospital with congestive heart failure. Transthoracic and transoesophageal echocardiograms (TTE\/TEE) revealed severe MR due to A2 (middle segment of the anterior leaflet) prolapse. Because of his high operative risk, we performed TEER. An NTW clip was placed between A2 and P2 (middle scallop of the posterior leaflet), markedly reducing MR to mild. Six months after TEER, he complained of dyspnoea, and severe MR was evident from both sides of the clip. Although the risk of iatrogenic mitral stenosis was considered, we assessed that there might be a chance to succeed in repeat clipping if the additional two clips were placed only in the P2 beside the original clip following a careful review of TEE images. We challenged repeat clipping. After we placed NT clips on each side of the original NTW clip, MR was reduced to mild without creating iatrogenic mitral stenosis, and his symptoms subsequently improved.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Anatomical features such as no valve thickening at the leaflet\u2019s grasping site and the presence of posterior leaflet indentation may increase the likelihood of a successful repeat clipping outcome. Repeat clipping should be considered after careful anatomical assessment, even in patients with challenging anatomy.<\/jats:p>\n
