Peripartum cardiomyopathy (PPCM) is a rare cause of pregnancy-related heart failure, which affects a woman during the last months of pregnancy or first months of parturition. Its etiopathogenesis is still unclear. Coexistence of PPCM with human immunodeficiency virus (HIV) has been scarcely analyzed. A low CD4 count is proposed to be one of the predictors of dilated cardiomyopathy in HIV. Here, a pregnant woman with HIV presented with signs of congestive heart failure for the first time during her last trimester. Echocardiography revealed a dilated cardiomyopathy with ejection fraction of 34% which proved the diagnosis of PPCM. She underwent cesarean section for impending previous scar rupture. Her status deteriorated subsequently in spite of all efforts and she succumbed due to ventricular tachycardia. This case necessitates an awareness regarding coexistence of HIV with PPCM and dreaded clinical sequences. Patients suffering from HIV should be treated well and their CD4 count should be improved before conception to avoid such complications in pregnancy.
