AB ESSENTIALS  OF  DIAGNOSISPredominant  biventricular  diastolic  dysfunction  with  lesser  impairment  of  systolic  performance.Symptomatic  presentation:Chronic  biventricular  “backward  failure”  manifest  as  dyspnea  and  peripheral  edema  (often  hepatomegaly  and  ascites).Reduced  preload  limits  cardiac  output  (fatigue).Echocardiography:  small  stiff  ventricles,  preserved  systolic  function  (until  late  stages),  dilated  atria,  and  diastolic  dysfunction  by  Doppler.Many  disorders  manifest  restrictive  “physiology”  and  must  be  excluded  (eg,  hypertrophic  cardiomyopathy  and  constrictive  pericarditis).Cardiac  magnetic  resonance  imaging  powerful:  delineates  myocardial  infiltration,  inflammation,  and  fibrosis  and  assesses  pericardium,  thereby  helping  establish  underlying  disorder.Tissue  biopsy  may  be  necessary  for  definitive  diagnosis  in  some  disorders  (eg,  amyloidosis).
