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.
