A 75-year-old woman was referred to our hospital with sudden onset of chest and back pain. She showed ventricular fibrillation during transportation and shock vitals on arrival at the hospital. An electrocardiogram (ECG) showed ST segment elevation in aVR, and emergency coronary angiography (CAG) was performed. CAG revealed malperfusion of the left main coronary artery (LMT) due to type A aortic dissection. Emergency percutaneous coronary intervention (PCI) was performed and coronary revascularization was achieved. Strict blood pressure management was performed in the intensive care unit. She underwent ascending aortic replacement two days after onset of the disease. Although she required long-term postoperative ventilator management, she did not develop low output syndrome (LOS). In this case, emergency PCI minimized myocardial ischemia, and LOS could have been avoided by waiting for circulation to recover and then performing surgery.
