Myocardial recovery after mechanical support for acute myocarditis: is sustained recovery predictable?
Background. At present, myocardial recovery with mechanical support for acute myocarditis is a more frequently observed issue. However, predictive parameters of a sustained myocardial recovery are still under investigation. Methods. Two recent cases of mechanical support for acute lymphocytic myocarditis with two different outcomes are reported. Literature about this disease and predictability of a sustainable myocardial recovery are reviewed. Results. Acute lymphocytic myocarditis is an individual entity whose outcome is associated with the importance of healed cell damage. Unfortunately, there are no available means of quantifying the fibrotic scar and endomyocardial biopsy has a high percentage of false-negative results. Echocardiographic assessment of systolic and diastolic cardiac function is difficult while under mechanical support and its significance is not obvious. Forthcoming development of Doppler could better correlate myocardial contractility and histology to be predictive
