CTICasesLeft Atrial to Left Ventricular Shunt
Imaging findings
Chest radiograph showed an unusual wavy marker on a sewing ring in a non-anatomic location. Contrast-enhanced CT confirmed a surgical bypass graft with a one-way valve connecting the left atrial appendage to the left ventricular apex.
Key takeaways
This extra-anatomic shunt was created to manage severe mitral stenosis in a patient who could not undergo standard valve replacement. It serves as a reminder to consider non-standard surgical plumbing in patients with a history of complex cardiac procedures.
