Acute coronary syndrome on non-electrocardiogram-gated contrast-enhanced computed tomography

Figure 9 Corresponding invasive coronary angiography and sestamibi single-photon emission computed tomography in acute coronary syndrome of right coronary artery. Same patient as Figure 8. A: Invasive coronary angiography showed total occlusion in the proximal site of the right coronary artery (arrow); B: Subsequent percutaneous coronary intervention was performed by balloon angioplasty and stent implantation. His laboratory data showed elevation of cardiac biomarkers (creatine kinase 1620 IU/L, creatine kinase MB 239 IU/L). Short axis (C) and vertical long axis (D) views and a bull’s eye polar plot (E) of rest technetium-99m sestamibi single-photon emission computed tomography myocardial perfusion imaging showed perfusion defect in the basal to mid inferior, inferolateral and inferoseptal wall of the left ventricle (arrows).
