Key result
A 42-year-old man with influenza A myocarditis demonstrated discordance between echocardiographic ventricular wall thickening and electrocardiographic findings, which reversed upon resolution.
Case Report (n=1)
This case highlights the potential discordance between echocardiographic wall thickening due to myocardial edema and ECG findings in acute influenza myocarditis.
Discordant echo wall thickening and ECG in acute influenza myocarditis warrants multimodal caution; this case leaves open diagnostic validation needs.
A 42-year-old man presented with a viral prodrome and tested positive for influenza A. He rapidly deteriorated developing cardiogenic shock, rhabdomyolysis, and acute kidney injury. Patient improved 1 week later with supportive measures including vasopressors, inotropes, and an intraaortic balloon pump. We report this case as it highlights the discordance between echocardiographic ventricular wall thickening as a result of myocardial edema, and electrocardiographic findings at presentation, with a reversal in findings at time of resolution. Additionally, there was some suggestion of a regional pattern to the reduced longitudinal strain.

Hawwa et al. (2015) conducted a case report in Influenza myocarditis (n=1). Supportive measures (vasopressors, inotropes, intraaortic balloon pump) was evaluated. A 42-year-old man with influenza A myocarditis demonstrated discordance between echocardiographic ventricular wall thickening and electrocardiographic findings, which reversed upon resolution.
