Aortic root abscess with fistula is rare in native valves after dissection repair. Transesophageal echocardiography is better than transthoracic for diagnosis, but cardiac MRI

Area of Science:

  • Cardiology
  • Medical Imaging
  • Cardiac Surgery

Background:

  • Aortic root abscess is a known complication of aortic valve endocarditis.
  • Previous repair of aortic dissection with a Dacron graft can alter aortic anatomy.
  • Fistula formation from the aortic root to the right ventricular outflow tract is uncommon.

Observation:

  • A rare case of aortic root abscess and fistula formation in a patient with a native aortic valve and prior aortic dissection repair is presented.
  • Transesophageal echocardiography demonstrated superior diagnostic capability compared to transthoracic echocardiography for aortic root abscess.
  • The diagnostic accuracy of cardiac MRI versus transesophageal echocardiography for this specific condition has not been previously studied.

Findings:

  • The study highlights an uncommon presentation of aortic root abscess and fistula.

  • Transesophageal echocardiography is confirmed as a valuable diagnostic tool for aortic root abscess.
  • A knowledge gap exists regarding the comparative diagnostic utility of cardiac MRI and transesophageal echocardiography in such cases.

    • Implications:

    • This case underscores the importance of considering rare complications even after aortic dissection repair.
    • Further research is warranted to compare the diagnostic performance of cardiac MRI and transesophageal echocardiography for aortic root abscess.
    • Improved diagnostic strategies may lead to earlier detection and better management of complex cardiac conditions.
