A 42-year-old male patient with a history of chest pain presented to the emergency room our hospital. MSCT angiography was performed using a 256-slice computed tomography (CT). The MSCT angiographic analysis showed a total occlusion of the medial left anterior descending artery (LAD) after the 2nd diagonal branch. An urgent coronary angiography performed later the same day, it excluded a significant coronary artery disease. Conclusion: In patients with tachykardia and arrhythmias, image quality is frequently affected by motion artefacts, limiting ist utility. Ventricular Extrasystoles can decrease image quality of coronary computed tomography.
