Key result
A 61-year-old female developed a 99% left main ostial coronary artery occlusion presenting as an NSTEMI 4 months after undergoing surgical aortic valve replacement.
Why the study?
Iatrogenic ostial coronary artery obstruction post-aortic valve replacement is rare but potentially catastrophic, making prompt investigation and early management crucial.

Coronary ostial stenosis is a rare but potentially fatal complication that can present months after surgical aortic valve replacement, requiring a high index of suspicion and prompt revascularization.
Post-AVR ACS warrants consideration of iatrogenic ostial occlusion; case reports leave open optimal prevention and screening strategies.
Iatrogenic coronary artery obstruction is one of many life-threatening complications associated with aortic valve replacement. Although very few cases of ostial coronary artery occlusion following cardiac surgery are reported, the consequences can be catastrophic due to increased risk of mortality. Due to the rarity, prompt investigation and early management are crucial to manage this catastrophic sequelae. We report a case in which a 61-year-old female presented with acute coronary syndrome 4 months after surgical aortic valve replacement and was found to have 99% left main ostial coronary artery occlusion.

Daniel et al. (2025) conducted a case report in Ostial left main stenosis post surgical aortic valve replacement (n=1). Surgical aortic valve replacement (SAVR) was evaluated on Ostial left main coronary artery occlusion. A 61-year-old female developed a 99% left main ostial coronary artery occlusion presenting as an NSTEMI 4 months after undergoing surgical aortic valve replacement.
