the cardiac syndrome is characterized grossly by cardiomegaly with hypertrophy , dilatation of ventricular chambers , and thinning of the apex of the left ventricle ( apical aneurysm ) and microscopically by focal areas of myocytolytic necrosis and myocardial degeneration with an inflammatory response composed of mononuclear cells ( predominantly macrophages and a few lymphocytes ) with concurrent interstitial fibrosis and occasional myofibers containing pseudocysts .
