Key result
Early supportive care and pericardiocentesis enable recovery in fulminant influenza A myocarditis with tamponade.
Why the study?
Recognizing subtle echocardiographic findings like preserved ejection fraction and diffuse left ventricular wall thickening facilitates early identification of fulminant myocarditis, prompting this report to highlight early diagnosis and supportive management.
Case Report (n=1)
Highlights the importance of early recognition and aggressive supportive management for fulminant influenza myocarditis presenting with cardiogenic shock and tamponade.
Early supportive management may aid recovery in fulminant influenza myocarditis with tamponade; single case leaves generalizability and echocardiographic patterns open.
Myocarditis is an infrequent complication of influenza infection that is most often diagnosed clinically in the setting of confirmed influenza infection and elevated cardiac enzymes. Pericarditis can also occur in cases of influenza myocarditis and may require pericardiocentesis for tamponade. Patients with fulminant myocarditis have cardiogenic shock; however, echocardiographic findings may be subtle, showing a preserved ejection fraction and diffuse left ventricular wall thickening (compared to baseline) due to inflammatory edema. Recognizing these echocardiographic findings in the appropriate clinical setting facilitates the early recognition of fulminant myocarditis. Therefore, we report a case of fulminant influenza A myocarditis in healthy 37-year-old women complicated by transient left ventricular wall thickening and tamponade, highlighting the importance of early diagnosis and supportive management for a successful outcome.

Radovanovic et al. (2022) conducted a case report in Fulminant Influenza A Myocarditis (n=1). Supportive management and pericardiocentesis was evaluated. A 37-year-old woman with fulminant influenza A myocarditis complicated by transient left ventricular wall thickening and cardiac tamponade successfully recovered with early diagnosis and supportive management.
