Key result
Improper placement of the Impella LP 2.5 device can cause severe hemolytic anemia, emphasizing the need for ultrasound guidance during insertion to avoid this complication.
Case Report (n=1)
Highlights the critical importance of using echocardiographic guidance during Impella placement to prevent severe hemolytic anemia.
Raises caution for Impella malposition causing hemolysis; hypothesis-generating and should not yet change practice.
The Impella LP 2.5 (Abiomed, Danvers, MA) has been a tool of use for high risk coronary procedures and for cardiogenic shock. As with any invasive or intracardiac device, improper placement can result in disastrous complications. Hemolytic anemia secondary to Impella implantation is one of the documented complications. However, cases of severe hemolytic anemia are rare in the literature. Proven imaging modalities like ultrasound need to be used to guide proper placement. We present a case of device induced severe hemolysis due to Impella insertion and the need to use ultrasound guidance to avoid such an unnecessary complication.

Cardozo et al. (2015) conducted a case report in Impella-induced severe hemolytic anemia (n=1). Impella LP 2.5 was evaluated. Improper placement of the Impella LP 2.5 device can cause severe hemolytic anemia, emphasizing the need for ultrasound guidance during insertion to avoid this complication.
