Aortic valve replacement successfully treated a 49-year-old man presenting with cardiac arrest and ECG changes mimicking left main coronary occlusion due to critical bicuspid aortic valve stenosis.

Severe stenosis of a bicuspid aortic valve can present as cardiac arrest with an ECG mimicking left main coronary artery occlusion.
Consider severe aortic stenosis in cardiac arrest with left main ECG mimic; extends differential awareness but leaves open prevalence and mechanisms.
A 49-year-old man presented to the emergency room after a cardiac arrest. On arrival, the patient's ECG showed ST-segment elevations in the aVR and anteroseptal leads with diffuse ST depression suggestive of left main coronary artery occlusion. Subsequent coronary catheterisation showed normal coronaries but revealed severe stenosis of his bicuspid aortic valve. A surgical replacement of the aortic valve was performed, and the patient recovered successfully.

Saxena et al. (2018) conducted a case report in Cardiac arrest due to critical bicuspid aortic valve stenosis (n=1). Aortic valve replacement was evaluated. Aortic valve replacement successfully treated a 49-year-old man presenting with cardiac arrest and ECG changes mimicking left main coronary occlusion due to critical bicuspid aortic valve stenosis.
