Key result
VA-ECMO and Impella 5.5 linked to fatal neurological injury in a fulminant myocarditis case.
Why the study?
The rare combination of refractory cardiogenic shock with acute severe mitral regurgitation from papillary muscle rupture illustrates therapeutic challenges with temporary mechanical circulatory support.

Warrants caution using tMCS for myocarditis with papillary muscle rupture; leaves open surgical intervention in profound cardiogenic shock.
Case Report (n=1)
This case illustrates the therapeutic challenges of managing fulminant myocarditis complicated by papillary muscle rupture and cardiogenic shock, demonstrating the use of VA-ECMO and Impella 5.5 for stabilization, though complicated by fatal neurological injury.
Lajoye et al. (2026) conducted a case report in Acute-on-recurrent viral myocarditis complicated by papillary muscle rupture and cardiogenic shock (n=1). VA-ECMO with left ventricular unloading using a micro-axial pump (Impella 5.5) was evaluated. In 1 patient with fulminant myocarditis and cardiogenic shock, management with VA-ECMO and Impella 5.5 ultimately led to severe neurological injury and withdrawal of life-sustaining therapies.
