Severe aortic regurgitation masked as sepsis-induced ARDS in a patient with endocarditis.

Septic shock is the most common type of shock in the intensive care unit with an associated mortality close to 50%. Infective endocarditis (IE) is a rare cause of septic shock but carries significant morbidity and mortality. Group B IE (GBS-IE) is an invasive infection with an incidence of approximately 1.7%. It affects immunocompromised patients such as intravenous drug users, alcoholics, those with HIV and elderly among others. IE with severe acute valvular heart disease challenges physicians when assessing fluid status during the early resuscitation in patients with septic shock. We present a case of GBS-IE complicated by severe acute aortic regurgitation with rapidly progressive acute respiratory failure in the setting of septic shock management.
