CTICasesPostoperative Fistula and Complications
Imaging findings
A patient with a complex history involving a fistula between the sinus of Valsalva and the left atrium, managed with a TEVAR/TAVR construct. Follow-up imaging while on VA-ECMO showed a dislodged and kinked coronary artery stent.
Key takeaways
Imaging patients on ECMO is challenging due to abnormal contrast kinetics; clinicians must carefully plan bolus tracking or consider briefly pausing ECMO flow for better visualization.
