Potential of the EVAHEART 2 Double-Cuff Tipless Inflow Cannula for Prevention of Thromboembolic Events

研究成果: ジャーナルへの寄稿学術誌査読


A 32-year-old man, who had developed fulminant myocarditis leading to asystole, underwent implantation of an EVAHEART 2 left ventricular assist system with a double-cuff tipless inflow cannula and a concurrent Fontan operation. Approximately 2 years after the simultaneous EVAHEART 2 implantation and the Fontan operation, the patient underwent heart transplantation. There was no device-related thromboembolism or pump malfunction under adequate antithrombotic management during the postoperative support period. Computed tomography showed no malposition of the inflow cannula irrespective of the left ventricular chamber size. Macroscopically, the left ventricular cavity of the excised heart revealed a smooth inflow ostium with appropriate intimal proliferation and without pannus or wedge thrombus formation. These findings suggest the utility of the double-cuff tipless inflow cannula for long-term clinical applications, which may lead to favorable outcomes during long-term patient management. The double-cuff tipless inflow cannula, which does not protrude into the left ventricular cavity, potentially contributes to the prevention of suction events and the collision of the inflow cannula with the interventricular septum and left ventricular free wall. Further investigation is required to confirm the role of the unique EVAHEART 2 inflow cannula in reducing thromboembolic events.
