"Aortic root abscess occurs as a complication of infective endocarditis in 10-37% 9. Abscess formation in post-surgical patients (aortic root repair and/or aortic valve replacement) is most commonly encountered in the first 5 years following surgery, most of which occur in the first 2 years."
"Pathology 2"
"Early abscessation occurs within the first 2 months of surgery and is usually caused by perioperative contamination such as from skin, wound or prostheses. Staphylococcus epidermidis and S aureus the most frequent causative pathogens."
"Late abscessation occurs greater than 2 months following surgery and resembles native valve endocarditis. Streptococci species are the most common causative pathogens."
"Abscesses tend to be saccular in shape, range from 1-3 cm in diameter. Depending on the sinus of origin, they may extend beneath the pulmonary trunk, right pulmonary artery, interventricular septum or mitral annulus."
