Anatomically corrected malposition of the great arteries (ACMGA) is an extremely rare congenital anomaly characterized by abnormal spatial arrangement of the great arteries despite ventriculoarterial concordance [1,3]. We present the case of a 2-month-old female infant who was initially misdiagnosed as having congenitally corrected transposition. Echocardiography revealed atrial situs solitus, ventricular d-loop, and l-malposition of the great arteries, accompanied by a muscular ventricular septal defect and left ventricular hypertrophy. Subsequent cardiac catheterization confirmed the diagnosis of ACMGA, with the aorta arising anteriorly from the left ventricle and the pulmonary artery posteriorly from the right ventricle. Hemodynamic measurements showed increased right ventricular pressure and left-to-right shunt. Multimodality imaging, including echocardiography and angiography, played a crucial role in establishing the correct diagnosis, thereby preventing misclassification as congenitally corrected transposition. This case highlights the importance of sequential segmental analysis and advanced imaging in the differentiation of rare congenital anomalies, which is essential for accurate diagnosis, management, and surgical planning.
