Mechanical Circulatory Support for Cardiogenic Shock in the Critically Ill

Madeline L Fryer, Leora B Balsam
Chest 2019 July 30
Patients requiring mechanical circulatory support (MCS) constitute a heterogeneous group whose needs have guided the development of a broad range of MCS devices. Appropriate patient and device selection are important for maximizing the potential benefit of these therapies. Currently available devices can be deployed percutaneously or surgically implanted. They can also be configured for left, right, or biventricular support and remain in place for hours to years, offering varying levels of flow. In the critical care setting, patients with the highest acuity have the worst outcomes when receiving an implantable long-term ventricular assist device (VAD), so shorter-term devices should be considered for stabilization and optimization prior to implantation of a long-term device. In this focused review for the critical care clinician, we discuss important considerations for identifying VAD candidates, the range of devices available to support them, bridging strategies that may improve outcomes for critically ill patients, and areas of ongoing research.
