Abstract
Materials and methods Retrospective study of 110 rtoF adults with native aorta, median age 30.9 (22.9-39.4) years were studied by cardiovascular magnetic resonance (CMR) at baseline, and at follow-up (median 6.3 [IQR:5.1-7.6] years). Aortic measurements were performed at sinus, sinotubular junction (STJ), and mid-ascending aorta level. AD was defined as diameter > 2 standard deviations larger than published normal Z-Scores, according to the age and body surface area.
Highlights
We examined features, progression and relations to outcomes of aortic dilatation (AD) in adults with repaired tetralogy of fallot
Sixty three percent of patients had AD, sinus dilatation was observed in 61% of the patients (Figure 1A) and 22% of the patients had associated with sinus dilatation, ascending aorta (AscAo) dilatation(Figure 1B)
Diameter increase was observed in 25% of patients at sinus, 21% at sinotubular junction (STJ) and in 35% at AscAo level, at a mean rate of 0.05 ± 0.1, 0.06 ±0.14 and 0.12 ±0.26 mm/year respectively
Summary
