Recurrent STEMI After Surgical Aortic Valve Replacement.

ABSTRACT:

Background

A 63-year-old man underwent surgical aortic valve replacement with an On-X valve using COR-KNOT suturing to facilitate a mini-sternotomy approach.

Case summary

The patient presented with recurrent inferior ST-segment elevation myocardial infarctions over a few-year period, despite optimal anticoagulation therapy. Repeated coronary angiography showed no obstructive coronary artery disease or thromboembolic occlusion. Intravascular ultrasound showed a filling defect in the ostium of the right coronary artery (RCA). A cardiac computed tomography confirmed the interference between a COR-KNOT and the RCA. Percutaneous coronary intervention of the RCA ostium was performed with good outcomes.

Discussion

This is the first case to report a ST-segment elevation myoca
