Key result
Stent barrier technique stabilizes large aortic root thrombus to prevent recurrent embolization before surgery.
Why the study?
Aortic root thrombus is a rare cause of acute coronary syndrome with limited treatment strategies, especially in centers with limited surgical facilities.
Case Report (n=1)
The stent barrier technique using a protruding drug-eluting stent can serve as an effective bridge to surgery for patients with aortic root thrombus causing acute coronary syndrome.
May stabilize select aortic root thrombus cases pending surgery; hypothesis-generating and should not yet change practice.
Aortic root thrombus is a rare cause of acute coronary syndrome, often linked to hypercoagulability or structural anomalies. A 58-year-old male presented with chest pain, hypotension, and Killip Class 3 findings. Electrocardiography suggested left main coronary artery (LMCA) occlusion, and coronary angiography revealed a large thrombus extending from the LMCA into the left anterior descending artery (LAD). Computed tomography identified an organized thrombus in the noncoronary sinus of Valsalva. A drug-eluting stent protruding 8 mm into the aorta was implanted from the LMCA to the LAD as a bridge to surgery. Surgical thrombectomy and coronary artery bypass grafting were performed, and pathology confirmed an organized thrombus. The stent barrier technique stabilizes aortic root thrombi and prevents recurrent embolization in repeated embolic events. It may serve as a bridging strategy in centers with limited surgical facilities.

Faideci et al. (2025) conducted a case report in Aortic root thrombus causing acute coronary syndrome (n=1). Stent barrier technique (drug-eluting stent protruding into the aorta) was evaluated on Stabilization of thrombus and prevention of recurrent embolization as a bridge to surgery. The stent barrier technique successfully stabilized a large aortic root thrombus and prevented recurrent embolization as a bridge to surgical thrombectomy and coronary artery bypass grafting.
