Left ventricular assist device is an established therapeutic option for the patient with end-stage heart failure. Recently, durable continuous-flow devices have replaced earlier generation of pulsatile devices and their desirable features are accelerating the utilization of these devices. However, their powerful performance could sometimes induce unfavorable complications such as sucking, especially in not so dilated left ventricle. Special maneuvers such as cannula position and lower pump speed may be reasonable for patients with non-dilated left ventricular, however, those managements have not been established yet to date. Right ventricular failure is also another concern in these devices. We experienced a patient who got a HeartMate II in spade-shaped, non-dilated left ventricle concomitant with right ventricular dysfunction, and successfully managed her.
