Deficiency of mannose-binding lectin, myopathy, calcified endomyocardial fibrosis, and left ventricular noncompaction

In a patient with mannose-binding lectin deficiency and metabolic myopathy with recurrent respiratory infections, left ventricular hypertrabeculation/noncompaction was diagnosed by echocardiography and confirmed at autopsy. In contrast with previously described cases, extensive endocardial calcifications were found, possibly as a result of recurrent endomyocarditis during the recurrent infections.
