Implantation of continuous-flow left ventricular assist device in a narrow lumen is technically challenging to secure an optimal support. We experienced a patient with the transposition of the great arteries after the Senning procedure who was initially implanted with Jarvik 2000®. She presented with worsening heart failure symptoms 2 years after implanting Jarvik 2000®. We assumed that the inflow cannula was stuck in the highly developed trabeculae on the interventricular septum, which disturbed the VAD to maintain an expected support. After converting to the EVAHEART® 2, we successfully obtained an adequate inflow. We consider that the tipless cannula of EVAHEART® 2 is the most suitable when there is no sufficient room to place a conventional inflow cannula in the systemic ventricle.
