Infective Endocarditis Involving Mitral and Aortic Valves With Interatrial Septal Abscess

Infectious endocarditis (IE) is an infection of the endocardial surface and frequently refers to the infection of one or more heart valves. The clinical manifestations of IE are highly variable, with fever being the most common symptom, along with other nonspecific symptoms such as chills, anorexia, malaise, and myalgias. IE is associated with various systemic complications including septic emboli, cardiac complications such as valvular vegetations and intracardiac abscess, neurologic complications, and systemic immune reactions. In this case report, we present a patient with an IE that involved both mitral and aortic valves as well as a unique pathology with an interatrial septal abscess.
