ABSTRACT
ObjectiveTo evaluate the feasibility of CT coronary angiography (CTCA) in patients with arrhythmia using 320-detector row CT.MethodsThirty-one patients with persistent atrial fibrillation and 8 patients with premature ventricular contraction were enrolled in this study.All patients underwent 320-detector row CTCA.CT image quality was evaluated with 4-point grading scale by two radiologists.Interobserver agreement was evaluated by Kappa statistics.The radiation dose was calculated.ResultsIn total510 coronary segments,496 (97.2%) segments met diagnostic standard.The mean effective dose was (12.7 ± 4.8) mSv in this study.There was a good agreement in image quality scoring between the two reviewers (Kappa =0.72 ).Conclusion 320-detector row CTCA is feasible in patients with atrial fibrillation and premature ventricular contraction.Arrhythmia may not be considered as a contraindication to CTCA.
