Surgical revascularization for severe spasm in the left main coronary artery

A 46‐year‐old woman who presented with severe stenosis with endothelial damage caused by recurrent spasm in the left main coronary artery received medical therapy. However, she developed severe coronary artery spasm, resulting in circulatory collapse, which was successfully treated with coronary artery bypass grafting. Surgical revascularization is effective for repeated coronary artery spasms resulting in circulatory collapse. Spasms can sometimes occur in other coronary arteries and may also occur in arteries of other organs.
