Timely multidisciplinary management and advanced mechanical circulatory support (VA-ECMO) can result in complete recovery in pediatric patients with fulminant influenza B myocarditis and cardiogenic shock.
Influenza is a common viral infection associated with seasonal outbreaks; however, fulminant myocarditis secondary to influenza Type B represents a rare and life-threatening complication in the pediatric population, with poorly understood pathophysiology. Only a limited number of cases have been reported worldwide, and to our knowledge, this is the first published case in Mexico. We report the case of a previously healthy 13-year-old girl who presented with a five-day history of nonspecific symptoms and rapidly progressed to cardiogenic shock. Prompt recognition and a multidisciplinary approach were essential, involving the pediatric cardiology, cardiac surgery, intensive care, and cardiac imaging teams. Advanced mechanical circulatory support was initiated, including an intra-aortic balloon pump and extracorporeal membrane oxygenation. Medical management included antiviral therapy, corticosteroids, and intravenous immunoglobulin. Following 45 days of intensive management, the patient demonstrated complete recovery of cardiac function and was discharged with close outpatient follow-up. This case highlights the importance of early recognition of fulminant myocarditis in pediatric patients with influenza infection and demonstrates that timely multidisciplinary management and advanced mechanical circulatory support can result in favorable outcomes, even in severe presentations.
Gilles-Herrera et al. (Thu,) conducted a case report in Adolescent (13-year-old female) with fulminant myocarditis secondary to Influenza B infection leading to cardiogenic shock (n=1). Venoarterial extracorporeal membrane oxygenation (VA-ECMO) with inotropic and vasoactive support, intra-aortic balloon pump (IABP), oseltamivir antiviral therapy, corticosteroids (methylprednisolone), intravenous immunoglobulin (IVIG) was evaluated on Complete recovery of cardiac function defined by normalization of LVEF and clinical stability leading to hospital discharge. VA-ECMO combined with multidisciplinary care enabled complete recovery of cardiac function and survival in a 13-year-old girl with influenza B-associated fulminant myocarditis and cardiogenic shock.
