Infective endocarditis of an aorto-right atrial fistula caused by asymptomatic rupture of a sinus of Valsalva aneurysm: a case report
Abstract
Asymptomatic rupture of a sinus of Valsalva aneurysm is rare. A fistula following rupture of a sinus of Valsalva aneurysm may cause infective endocarditis. Here, we report a case of infective endocarditis of an aorto-right atrial fistula caused by asymptomatic rupture of a sinus of Valsalva aneurysm. A 45-year-old male, who was first diagnosed with a heart murmur at the age of 37 years, presented with fever. Blood culture was positive for Streptococcus gordonii. Ultrasound echocardiography revealed an aorto-right atrial fistula caused by rupture of a sinus of Valsalva aneurysm. After the infective endocarditis was healed by antibiotics, we successfully performed surgical repair of the aorto-right atrial fistula. Although asymptomatic rupture of a sinus of Valsalva aneurysm is uncommon, it should be recognized as a possible cause of infective endocarditis.
