Acute ST Elevated Myocardial Injury due to Coronary Thrombosis during Thoracic Endovascular Aortic Repair in Patient with Protein S Deficiency

ABSTRACT

A 71-year-old woman who had suffered from pulmonary thromboembolism with deep vein thrombosis for 12 years presented the hospital with a huge thoracic aortic aneurysm. During thoracic endovascular therapy, she had a sudden coronary artery occlusion without having organized stenosis or plaque rupture even under the dual antiplatelet treatment and heparinization. She turned out to be having a protein S deficiency. A procedure related thrombotic adverse event in patient with protein S deficiency is very rare, so we report a case with literature review.
