We describe a case in which aortic insufficiency occurred after Impella insertion, required extra surgical intervention twice. A 33-year-old man with familial dilated cardiomyopathy was admitted to our hospital due to acute decompensation of heart failure. Despite intensive medical treatment, his hemodynamic status did not improve. Firstly, Impella was emergently implanted, and HeartMate III (Abbott, Plymouth, MN, USA) implantation was performed 2\u00a0weeks after. In the HeartMate III implantation, new aortic insufficiency had revealed and central aortic valve closure was performed concomitantly. However, on postoperative Day1, the coaptation stitch had untied, causing severe aortic insufficiency which led to another emergent operation of aortic valve replacement. We suggest that indications for Impella implantation need to be carefully discussed beforehand, especially with patients who may undergo implantation of left ventricular assist device.<\/jats:p>","DOI":"10.1093\/jscr\/rjab420","type":"journal-article","created":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T11:19:00Z","timestamp":1631099940000},"source":"Crossref","is-referenced-by-count":5,"title":["Aortic
