Key result
Impella 5.5 support was evaluated using a novel approach to assess biventricular pressure-volume loops in a 50-year-old man with heart failure and cardiogenic shock.
Why the study?
Identifying patients with cardiogenic shock and RV dysfunction needing biventricular versus isolated LV support remains challenging, requiring rigorous hemodynamic evaluation of biventricular contractility and load.

Single-case biventricular PV loop assessment during LV support is feasible; hypothesis-generating and requires prospective validation before clinical adoption.

This case report describes a novel approach to assess biventricular pressure-volume loops in a patient receiving Impella 5.5 support for cardiogenic shock.
Everett et al. (2021) conducted a case report in acute decompensated heart failure and cardiogenic shock (n=1). Impella 5.5 was evaluated on biventricular pressure-volume loops. Impella 5.5 support was evaluated using a novel approach to assess biventricular pressure-volume loops in a 50-year-old man with heart failure and cardiogenic shock.
