Abstract

Background: The most frequent arrhythmia is atrial fibrillation (AF), whereas the most prevalent cardiovascular disease is coronary artery disease (CAD). Aim of the work: To evaluate diagnostic accuracy of multislice computed tomography (MSCT) coronary angiography in assessment of CAD in patients with controlled AF. Patients and methods: This study was conducted on 43 patients attended to Cardiology clinic of Al-Azhar University Hospitals, Air Forces Specialized Hospital and National Heart Institute. All patients had AF and subjected to MSCT angiography and any patient with any degree of stenosis will be subjected to invasive coronary angiography. Results: Image quality was evaluated, 33 patients (76.7%) as good, 10 patients (23.3%) as moderate, and no patients (0%) as poor image quality. Twenty five patients had normal CT angiography and 18 patients who have lesion were subjected to invasive coronary angiography within 30 days. Specificity, sensitivity, PPV, NPV, and accuracy were 88.9%, 77.8%, 80%, 87.5%, and 83.3%, respectively, per patient. Specificity, sensitivity, PPV, NPV, and accuracy were 90.9%, 97.5%, 83.3%, 98.72%, and 96.7%, respectively, per artery. Sensitivity, specificity, PPV, NPV, and accuracy were 90.9%, 98.5%, 83.3%, 99.2%, and 97.9%, respectively, on a segment basis. Conclusion: Our research showed that, when used in conjunction with managed atrial fibrillation, MSCT coronary angiography can detect substantial coronary artery disease in individuals with equivalent high sensitivity, specificity, and diagnostic accuracy to invasive coronary angiography. Most patients had high-quality images.
