Visualization of HeartMate 3 Outflow Graft Twisting by Selective Graft Angiography

A 55-year-old male patient presented with a history of left ventricular assist device (LVAD) implantation due to ischemic cardiomyopathy. Low-flow alarms were detected on the LVAD, which was temporarily stopped to demonstrate retrograde flow from the aorta through the outflow graft. Selective visualization was performed after engagement of a pigtail catheter in the outflow graft. Twisting at the beginning of the outflow graft was clearly depicted. The patient underwent surgery to correct the twisting. After correction, flow increased immediately back to normal levels.
