Severe cardiogenic shock due to acute onset of an aorto-to-right atrial shunt in a patient with aortic valve endocarditis.
BACKGROUND
Heart failure is the most common cause of death due to infective endocarditis. We report a case of a patient presenting with severe shock due to an infection-associated left-to-right cardiac shunt.


METHODS
A 62-year-old man, who underwent aortic valve replacement five years previously, was admitted to ICU due to acute hemodynamic deterioration. A few days earlier, he had a septic episode with blood cultures positive for Staphylococcus aureus and clinical features of infective endocarditis. In ICU, transthoracic echocardiography revealed shunting from the aortic root to the right atrium resulting in severe cardiogenic shock.


CONCLUSIONS
This case report describes a near fatal complication of infective endocarditis, detected by routine use of transthoracic echocardiography.


CONCLUSIONS
Our case outlines the relevance of early cardiac surgery strategies in patients with infective endocarditis and we briefly discuss the current literature.
