Mechanical Circulatory Support -

By using PV loops as a feedback mechanism, one can optimize a patient’s hemodynamic state resulting from acute or long-term mechanical circulatory support. Quantitative measures of ventricular energetics, diastolic function, and dyssynchrony provide a comprehensive assessment of hemodynamic function tailored specifically to that patient.

This video showcases left ventricular unloading caused by an intra-aortic balloon pump (IABP). The LV PV loops begin at a “baseline” state, with the IABP being turned on at (0:09).

This video showcases left ventricular unloading by a percutaneous left ventricular assist device (pVAD).
