title: Resolution of Intractable Ventricular Tachycardia After Surgical Repositioning of a HeartMate II Inflow Cannula.
abstract: Ventricular arrhythmias are common after left ventricular assist device implantation. Malposition of the inflow cannula is one of the few etiologies with a mechanically correctable defect. We present a case of intractable ventricular tachycardia that resolved after surgical repositioning of a HeartMate II inflow cannula. The diagnosis and management of this case demonstrate the utility of imaging studies for detecting inflow cannula malposition and the efficacy of inflow cannula repositioning for treatment.
