| Zusammenfassung: | Atrial fibrillation (AF) is the most common persistent arrhythmia. It is associated with wide range of cardiac clinical conditions. Because of variable duration of cardiac cycle resulting in reduced image quality, AF has been considered relative contraindication for performing coronary computed tomography angiography (CCTA). However, recent reports have suggested that newer dual source scanner with higher temporal resolution can be used in patients with AF (Oncel et al., 2007; Wolak et al., 2008; Rist et al., 2009). Image quality can be maintained if heart rate is lowered to less than 70 beats per minute. However, high heart rate can still be challenging. Mapping systolic phase with the use of absolute delay reconstruction algorithm has been shown to provide better image quality. In this article, we present a case of patient with chronic AF and in whom coronary examination was required before going to repair of aortic root dissection. CCTA, with the use of absolute delay reconstruction algorithm, provided diagnostic image quality of the coronary arteries |
