Background: The differential diagnosis of peripartum chest pain and cardiogenic shock is broad and includes pulmonary embolism, amniotic fluid embolism, peripartum and Takotsubo cardiomyopathy, myocardial infarction, and anaesthetic complications.
Case: A 31-year-old woman with Addison's disease underwent an elective caesarean section that was complicated by chest pain and cardiogenic shock. After initial resuscitation, she was transferred to a tertiary hospital, and urgent transthoracic echocardiography revealed severe systolic dysfunction.
Study Objective: To assess the usefulness of narrowband imaging (NBI) to detect additional areas of endometriosis not identified by standard white light in patients undergoing laparoscopy for the investigation of pelvic pain.
Design: A prospective cohort trial (Canadian Task Force classification II). Evidence obtained from a well-designed cohort study.
