Right cardiac echinococcosis with coronary compression. Description of a clinical case

: An outstanding case of cardiac echinococcosis is described. Clinical symptomatology was characterized by typical nitroglycerin-responsive crisis of angina pectoris associated to an electrocardiographic pattern of negative T wave on anterolateral and inferior leads. The diagnosis was suspected on the basis of thoracic computerized tomography and coronary arteriography. The anatomical localization was mainly pericardial but the right ventricle was involved too. Left anterior descending artery was dislocated and squeezed.
