Observational StudyCorrelation Between Total Repair Timing and Late Aortic Root Dilatation in Repaired Tetralogy of Fallot.
Aortic root dilatation is frequently encountered in adults with repaired Tetralogy of Fallot (TOF). The timing of total repair is known to have a significant correlation with late aortic root dilatation, but it is not well established. The objective of this study was to investigate the risk factors and correlation with timing of total repair for aortic root dilatation in adults with repaired TOF. ⋯ Late total repair was a significant risk factor for late aortic root dilatation in repaired TOF. However, early total repair did not always prevent late aortic root dilatation. These results suggest that congenital aortic pathology may also be a possible cause of aortic root dilatation along with longstanding hemodynamic stress.
