Aortic coarctation diagnosed by 64-slice computed tomography angiography

64-slice peripheral computed tomography angiography: a clinical accuracy evaluation.

Aortic Coarctation: Evaluation with Computed Tomography Angiography in Pediatric Patients

Background: Aortic coarctation is a congenital narrowing of the aorta. Computed tomography angiography is used to detect aortic coarctation and determine its extent and severity. Objective: To assess pediatric aortic coarctation by computed tomography (CT) angiography. Material and Methods: This study included eighteen patients (10 males and 8 females) who were clinically diagnosed to have coar...

Aortopulmonary window and interrupted aortic arch in a neonate assessed by 64-slice computed tomography.

MOTS CLÉS Fenêtre A newborn baby, born prematurely at 34 weeks’ gestation, had a neonatal diagnosis of aortopulmonary window after respiratory distress at 6 days of life, with a systolic heart murmur. He underwent two-dimensional echocardiography, which depicted an 8mm defect between the aorta and the pulmonary artery with a massive left-to-right shunt (Fig. 1). Dual-source 64-channel multidete...

Feasibility of ultra-low contrast 64-slice computed tomography angiography before transcatheter aortic valve implantation: a real-world experience.

AIMS To investigate the feasibility, image quality, and clinical implications of an ultra-low-dose contrast injection computed tomography angiography (CTA) protocol in patients scheduled for transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS Images obtained with 64-slice CT were retrospectively evaluated in 162 TAVI candidates with a body mass index (BMI) of ≤29 kg/m(2). A mu...

Incidental finding of an aortic valve mass on 64-slice computed tomographic coronary angiography.

Quiz A 41-year-old Chinese man with a background history of hypertension for 8 years underwent a computed tomography coronary angiography for an evaluation of atypical central chest pain. This revealed a coronary artery calcium score of zero with no signifi cant stenosis seen in any of the coronary arteries. There was an incidental fi nding of a 9 x 6 mm fi lling defect attached to the right co...
