Abstract

Objectives To evaluate the outcomes of reintervention for postrepair recoarctation in young children.

Methods Between January 2011 and December 2020, all consecutive patients aged ≤3 years who were treated for postrepair recoarctation were included. Recoarctations were classified into two morphological types by three-dimensional imaging. Two methods, namely, surgical repair and balloon angioplasty (BA), were used to treat recoarctation.

Results This study included 50 patients with a median age of 10.5 months (range, 2.0–36.0 months) and a mean weight of 9.3 ± 3.1 kg. Hypoplastic recoarctation occurred most frequently in patients who had undergone patch aortoplasty at initial repair (p = 0.001). No hospital mortality occurred, and all patients achieved an increased diameter (p < 0.001) and a decreased pressure gradient (p < 0.001) at the recoarctation site immediately after reintervention. The median follow-up time after reintervention was 3.5 years (range, 16.0 days–9.6 years). Late mortality occurred in four patients (8.0%): two in the surgical group and two in the BA group (chi-square test= 0.414, p = 0.520). There was no difference in arch reobstruction after reintervention between the surgical and BA groups (chi-square test = 1.383, p = 0.240). Recoarctation with a hypoplastic morphology was the leading risk factor for arch reobstruction after reintervention (hazard ratio, 6.552; 95% confidence interval, 2.045–20.992; p = 0.002).

Conclusion Reintervention for recoarctation has favorable early outcomes in young children. However, late mortality is not rare, and arch reobstruction is common during close follow-up. For young children, recoarctation with hypoplastic morphology is the leading risk factor for reobstruction, while the choice of reintervention method exerts little effect on the outcomes of arch reintervention.
