Aortic Valve Staphylococcus Aureus Endocarditis Complicated by Sinus of Valsalva-Right Atrial Fistula

Abstract

Infective Endocarditis is an extremely rare etiology of sinus of Valsalva-right atrial fistulas, abnormal connections between the aorta and the right atrium. We report the case of a 21-year-old female patient with native aortic valve Staphylococcus aureus endocarditis complicated by sinus of Valsalva abscess perforation associated with an acute heart block, an aorto-right atrial fistula, severe heart failure, and cardiogenic shock. The patient underwent emergent aortic valve replacement and complex sinus of Valsalva fistula pericardial patch reconstruction and repair. Choice of valve and patient-prosthesis mismatch are discussed.
