Abstract
We present the case of a 18-year-old female with fulminant lymphocytic myocarditis caused by Parvovirus B19 (PVB19), successfully treated using temporary LVAD. In the literature there is no consensus on the surgical strategy. While some surgeons prefer to use a single device supporting only the LV, others prefer to start immediately with a biventricular supporting. At pre-procedural ultrasound evaluation, her anatomical features were not suitable for a percutaneous device such as the Impella. Thus, a temporary paracorporeal continuous flow LVAD was inserted. The heart recovery allowed LVAD removal 9 days after the implant.

Case presentationAcute myocarditis has various aetiologies, and clinical presentation and specific treatments could be very different [1]
We present a case of fulminant lymphocytic myocarditis caused by Parvovirus B19 (PVB19) infection, treated successfully by temporary left ventricle assist device (LVAD) implantation
The pathogenetic role of PVB19 genomes in myocarditis has not yet been sufficiently elucidated, Bock et al suggested that PVB19 viral loads of more than 500 ge per microgram in endomyocardial biopsy specimens are a clinically relevant threshold for the maintenance of myocardial inflammation [4]
Summary
Acute myocarditis has various aetiologies, and clinical presentation and specific treatments could be very different [1]. We present a case of fulminant lymphocytic myocarditis caused by Parvovirus B19 (PVB19) infection, treated successfully by temporary left ventricle assist device (LVAD) implantation
