Long-term reintervention on LVOT and mortality by IAA type, arch aberrancy and IAA type B and arch aberrancy in combination. Long-term reintervention is compared using the Kaplan–Meier method for patients by IAA type (A), patients with and without AAb (B) and among those with both IAA-B + AAbS compared to all others (C). Long-term mortality is compared only for IAA type A versus type B due to 100% survival of AAb patients (D). Log-rank P value is displayed. AAb: arch aberrancy; AAbS: aberrant subclavian; IAA: interrupted aortic arch; IAA-B + AAbS: IAA type B with concomitant aberrant subclavian.
