Abstract:

Patent Ductus Arteriosus (PDA) is a kind of congenital heart disease, which means that ductus arteriosus connecting the junction of the main or left pulmonary artery to the descending aorta remains patent beyond 3 months of life in full-term infants and beyond 1 year in premature infants. The classic murmur of PDA may be the first clue to its presence, and it may be detected by transthoracic echocardiography, computed tomography, or magnetic resonance angiography. Dynamic CT Angiography (4D-CTA), by multiple subsequent CT acquisitions or a continuous volume CT acquisition for a period of time, has been developed in recent years as a technique that combines the noninvasive nature of CT angiography with the dynamic acquisition of DSA. This case reported a 11-year-old female child with PDA detected by 4D-CTA for the first time and demonstrated that 4D-CTA enables the noninvasive evaluation of morphology of PDA as well as flow dynamics of the ductus arteriosus.
