Pregnant intravenous drug user tricuspid valve infective endocarditis treated with a successful simultaneous valve replacement and Cesarean section.

A 30-year-old female patient known to be an intravenous drug user (IVDU) was admitted to Bajcsy-Zsilinszky Hospital Cardiology Intensive Care Unit at 29-week gestation with severe sepsis and right heart failure. She had methicillin-sensitive Staphylococcus aureus on blood culture. Echocardiography confirmed the diagnosis of tricuspid valve infective endocarditis (IE). She had acute deterioration and hemodynamic instability for which an emergency tricuspid valve replacement (TVR) with a simultaneous Cesarean section (CS) was performed simultaneously. Medical management is the standard treatment in IE of IVDU pregnant patients, but in case of life-threatening complications, emergency TVR and CS are to be considered. This is the first reported case of IVDU IE treated with simultaneous TVR and CS.
