[Pulmonary edema occurring 2 days after elective cesarean section].

Two days after an elective Caesarean section, a 30-year-old woman suffered a pulmonary oedema. The diagnosis of cardiomyopathy was obtained with echocardiography, right heart catheterization and a myocardial biopsy. Peripartum cardiomyopathy is defined as a heart failure occurring in the last trimester of pregnancy or up to the third postpartum month and the lack of another etiology. The cause of myocarditis resulting in peripartum cardiomyopathy remains yet unknown. An immunosuppressive therapy can be associated with the treatment of the congestive heart failure.
