Key result
Angiography safely identifies aortic root abscesses and fistulas in endocarditis with 0% complication rate.
Why the study?
Abscesses in the aortic root are a serious complication of infective endocarditis requiring accurate diagnosis for antibiotic and surgical management.
Observational (n=19)
Angiography can safely identify the anatomical characteristics, extensions, and fistulas of aortic root abscesses complicating infective endocarditis.
Angiography detects aortic root abscesses in endocarditis; leaves open its role versus contemporary cross-sectional imaging.
Abscesses in the aortic root are a serious complication of infective endocarditis and require accurate diagnosis for antibiotic and surgical management. Nineteen cases of endocarditis of a native valve or prosthetic valve and adjacent abscess cavities were identified with angiography. Of 6 patients with endocarditis of a native valve, 5 had bicuspid aortic valves and all had severe aortic regurgitation. Of 13 patients with endocarditis of a prosthetic aortic valve, all had paravalvular regurgitation. Abscesses in the aortic root were saccular, ranged from 1 to 3 cm in diameter, and, depending on sinus of origin, extended beneath the main and right pulmonary arteries or into the interventricular septum or mitral anulus. Fistulas were detected into the mitral anulus in 8 patients, and into the right ventricle in 3 patients. No complications from the catheterization were recorded during the 48-hour follow-up.
