An unusual problem associated with the use of left ventricular assist devices (LVADs) relates to malposition of the apical inflow cannula. From 2005 to 2010, we implanted 154 continuous-flow HeartMate II (Thoratec, Pleasanton, CA) LVADs at our institution. In 4 separate instances, patients appeared to have malposition of the inflow cannula that resulted in serious symptoms. All 4 patients underwent surgery to reposition the cannula. Successful outcomes were achieved for 3 of the 4 patients.
