Cytomegalovirus myocarditis following liver transplantation

Cytomegalovirus (CMV) infections are commonly found in patients on immunosuppressive therapy following liver transplantation. However, acute myocarditis is an extremely rare manifestation of CMV infection in this setting. We report the case of a patient who developed acute myocarditis with severe biventricular failure with a cardiac ejection fraction of less than 10%, 6 weeks following orthotopic liver transplantation. Systemic CMV infection was diagnosed on the basis of a clinical viraemia, the presence of CMV antigen in urine, blood, and throat swab, and an associated four-fold rise in serum antibody titres to CMV. A full recovery ensued following treatment with standard anti-cardiac failure therapy and a 10 day course of intravenous ganciclovir.
