A patient with acute coronary syndrome and shock due to occlusion of both native coronaries and bypass grafts who was rescued by revascularization.

A 72-year-old male was admitted to our hospital because of chest pain in a pre-shock condition. He underwent coronary artery bypass grafting (CABG) 25 years prior. The most recent coronary angiography revealed total occlusion of both native coronaries and the saphenous vein graft (SVG) that was anastomosed to the right coronary artery. Emergency coronary angiography revealed that his SVG anastomosed to the left circumflex artery (LCX) and the distal left anterior descending artery (LAD) were also occluded. Emergency revascularization of the SVG anastomosed to the LCX and distal LAD restored blood flow and hemodynamic function. Subsequently, he received reoperative CABG to the LCX and LAD, and his angina and chronic heart failure improved. Careful follow-up is needed in patients having an old and deteriorated SVG. < We treated a patient with acute coronary syndrome in a pre-shock condition. His native coronary arteries and bypass graft were totally occluded. Due to the pre-shock condition, we selected emergency revascularization, and he recovered.>.
