Distensibility and Diameter of Ascending Aorta Assessed by Cardiac Magnetic Resonance Imaging in Adults With Tetralogy of Fallot or Complete Transposition

摘要: Structural abnormalities of the medial aorta have been described for conotruncal defects (e.g., tetralogy Fallot [TOF] and complete transposition great arteries (dextrotransposition [d]-TGA). In TOF, progressive aortic dilation is a frequent finding. patients with d-TGA an atrial switch, this problem less often described. The aim present study was to compare extent dilative aortopathy distensibility in adults switch procedure (n = 39) that repaired TOF controls 39), using cardiac magnetic resonance imaging. groups were matched age gender. Diameters indexed body surface area significantly increased compared at sinus up level right pulmonary artery. On multivariate testing, diagnosis defect (β 0.260; p 0.003) regurgitant fraction 0.405; <0.001) independent predictors diameter. Ascending reduced those controls: 3.6 (interquartile range 1.5 4.4) versus 2.8 2.0 3.7) 5.5 4.8 6.9) ×10(-3) mm Hg(-1) (p <0.001). ascending 0.028). conclusion, intrinsic aortopathy, manifested as diameters distensibility, not only evident but also procedure. Long-term follow-up needed monitor size both patient groups.
