Imaging Diagnosis of Endomyocardial Fibrosis / 实用放射学杂志

ABSTRACT

Objective To investigate the value of imaging diagnosis of endomyocardial fibrosis(EMF).Methods Imaging findings of 28 cases of EMF were restrospectively analyzed.Results There were three typesright ventricle type(n=21),left ventricle type(n=1),and dual ventricle type(n=6).The misdiagnostic rate of EMF by X-ray plain films was high(18/28). On angiography and MRI right ventricle type presented as shortened,deformed inflow-tract,obliteration of apex and dilated outflow-tract,marked tricuspid valve regurgitation(TR) and enlarged right atrium,even dilated superior vena cava,left ventricle type presented as narrowiug and deformed inflow-tract,small and deformed left ventride,even no markedly volume changes in relaxation or contraction,obtuse cardiac apex and mitral regurgitation.Dual ventricle type owned manifestations in the two types mentioned above,but predominated by right ventricle type. Conclusion In diagnosis of EMF X-ray plain films are of less value while MRI and cardioangiography are significant,MRI is a valuable non-invasive method,it can substitutd for cardioangiography as the first choice in diagnosing EMF.
