COMPARATIVE ANALYSIS OF THE FINDINGS OF CT ANGIOGRAPHY AND ECHOCARDIOGRAPHY IN AORTIC ARCH ANOMALIES

Abstract

The retrospective study was conducted in the Department of Cardiology Nishtar Medical Hospital Multan from January 2021 to January 2022 to compare CT angiography and echocardiography findings in patients with aortic arch abnormalities. The study was conducted on a total of 200 patients. Patient data was recorded, including demographic details and CT angiographic and echocardiographic findings. Results showed that Anomalies of coarctation of the aorta (COA) were most commonly reported. The most common anomalies associated with aortic arch anomaly included patent ductus arteriosus (PDA), patent ductus arteriosus (PDA), and ventricular septal defect (VSD). Of 200 patients, 66 (33%) had normal CT results, while 64 (32%) had normal transthoracic ECG results. For aortic arch anomalies, the specificity and sensitivity of TEC were 100% and 58%, and the agreement between CT angiography and TEC was .72 (Kappa coefficient). For COA, the specificity and sensitivity of TEC were 100% and 90%, and agreement in both modalities was 0.93. Transthoracic echocardiography was unable to detect congenital anomalies in a few cases. CT angiography provides better imaging quality and anatomical coverage and can be used to improve diagnostic accuracy.
