Why the study?
Fulminant myocarditis mimicking catastrophic surgical failure after minimally invasive endoscopic mitral and tricuspid valve repair is rare.
Case Report (n=1)
Fulminant myocarditis can mimic acute surgical failure after mitral valve repair, and management with systemic glucocorticoids alongside temporary mechanical circulatory support (VA-ECMO and Impella CP) can achieve myocardial recovery.

Acute LV failure post-valve repair may reflect myocarditis; single case leaves open benefit of MCS plus steroids.
We report a rare case of a 43-year-old woman who developed severe acute left ventricular dysfunction after minimally invasive endoscopic mitral and tricuspid valve repair. Coronary angiography excluded an ischemic complication, while endomyocardial biopsy showed interstitial edema and sparse inflammatory infiltrates without definitive evidence of active myocarditis. Systemic glucocorticoid therapy was initiated after the biopsy result. Temporary mechanical circulatory support with venoarterial extracorporeal membrane oxygenation and Impella CP enabled myocardial recovery and a favorable clinical outcome.

Tomczyk et al. (2026) conducted a case report in Fulminant myocarditis with severe acute left ventricular dysfunction after mitral and tricuspid valve repair (n=1). Systemic glucocorticoid therapy and temporary mechanical circulatory support (VA-ECMO and Impella CP) was evaluated on Myocardial recovery and clinical outcome.
