Peripartum cardiomyopathy(PPCM) is a relatively rare form of acute heart failure, which may result in severe cardiac failure and death. In part this may be due to late diagnosis and inappropriate treatment. Also diagnosis in the last trimester is complicated by the fact that the early symptoms of this disorder may mimic the symptoms of normal pregnancy. We experienced and reported a 35-year-old primigravida who was diagnosed with PPCM and undertaken emergency cesarean section with epidural anesthesia. PPCM must be considered in any patient who presents with newly onset of peripheral edema, dyspnea on exertion, or paroxysmal nocturnal dyspnea during late pregnancy or up to 5 months postpartum. We suggest that early and precise diagnosis is associated with a better outcome.
