We experienced a rare case of intraoperative type A aortic dissection during HeartMate II (Abbott, Chicago, IL) implantation and subsequently performed emergent total aortic arch replacement. Periodic follow-up computed tomography confirmed that the residual false lumen after the aortic repair had gradually thrombosed over time regardless of sufficient antithrombotic therapy. We analyzed the chronologic changes in the false lumen morphology, showing transient enlargement of the aortic diameter 1 year postoperatively and then a reduction at 3 years postoperatively. We report on the fate of residual false lumen after aortic repair under continuous-flow left ventricular assist device circulation.
