Abstract:

This case report describes a 22-year-old primigravida admitted at 40⁺¹ weeks of gestation for delivery. Due to arrest of labor, an emergency cesarean section was performed. Postoperatively, the patient developed recurrent high fever, respiratory symptoms, and manifestations of heart failure. Through multi-disciplinary team consultation, a definitive diagnosis was established: puerperal infection complicated by bacterial pneumonia, and peripartum cardiomyopathy with cardiac insufficiency induced by severe infection. Treatment consisted of antibiotic therapy with Piperacillin-Tazobactam combined with minocycline, and anti-heart failure management centered on Sacubitril-Valsartan, metoprolol, and diuretics. The patient's infection was effectively controlled, and her cardiac function along with related parameters returned to normal. The patient was discharged on postoperative day 15 following recovery. Severe infection is a significant risk factor for triggering perinatal cardiomyopathy. For pregnant women presenting with complex and critical postpartum complications, early recognition, timely initiation of the multidisciplinary collaborative approach, and implementation of individualized comprehensive treatment are crucial for successful management and improved prognosis.
