Extensive Myocardial Calcification in a Heart Transplant Patient

A 33-year-old female patient underwent heart transplantation (Tx) for valvular heart disease, where the surgical procedure was uneventful. Post-Tx, she developed with acute graft dysfunction, acute renal failure (ARF) requiring dialysis and septic shock. Bloodstream infection confirmed by treatment for carbapenemase-producing Klebsiella pneumoniae. Non-contrast-enhanced computed tomography (CT) of the chest and abdomen was done for investigation of the infectious focus and distention of the abdomen and melena, with extensive left ventricular myocardial calcification (MC) not previously found in CT (, and ). A diagnosis of cytomegalovirus (CMV) infection was also confirmed by upper digestive endoscopy findings with diffuse gastroduodenal ulcers and quantitative detection of positive CMV DNA, and the patient received ganciclovir. The patient became refractory to treatment and died.
