Aorto-left atrial fistula diagnosed with computed tomographic angiography: A case report


      • Aorto-Left Atrial fistulas are a rare complication of valve replacement procedures
      • While this entitiy can be evaluated with echocardiography, Cardiac CT has advantages in assessing for closure planning
      • Aorto-Left Atrial fistulas can present in patients with heart failure type symptoms due to a left-to-left shunt.
      • Percuatenous closure of aorto-atrial fistulas can be achieved with ventricular septal defect occlusion devices


      Aorto-atrial fistulas are a rare diagnosis with limited reports in the clinical literature. These findings are often characterized by echocardiography alone; however, the advent and increased availability and use of CT angiography to diagnose cardiac abnormalities provides improved anatomic visibility of potential defects. We are reporting a case of a 76-year-old male with decompensated heart failure secondary to a fistula between the aorta and left atrium after remote history of bioprosthetic aortic valve replacement.
