Summary

Coronary arterial disease is a risk factor for bariatric surgery and might be a predictor for later major adverse coronary events. Diagnosis of coronary arterial disease would thus be desirable for obese patients, however percutaneous angiography is an invasive procedure and associated with a certain morbidity in obese patients. In this study the investigators would like to assess whether dual source CT angiography can be used for diagnosis of coronary arterial disease in severely obese patients and which settings yield the best image quality.
