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.
与左心室辅助装置（LVAD）使用相关的一个不常见问题与心尖部流入管的错位有关。在 2005 年至 2010 年间，我们在本院植入了 154 个连续流 HeartMate II（Thoratec，加利福尼亚州普莱森顿）LVAD。在 4 个单独的情况下，患者似乎出现了流入管错位，导致严重的症状。所有 4 名患者均接受了重新定位管的手术。其中 3 名患者的手术取得了成功。
