Surgical reintervention for recurrent coarctation of the aorta is effective, with low mortality and no spinal injuries. Most patients achieve normotension post-surgery, indicating successful management of this complex congenital heart defect.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Recurrent stenosis after coarctation repair leads to significant long-term morbidity.
  • Persistent or exercise-induced hypertension can signal recurrent coarctation.
  • Surgical intervention is indicated for patients unresponsive or unsuitable for balloon dilation.

Purpose of the Study:

  • To evaluate the outcomes of surgical reintervention for recurrent aortic coarctation.
  • To assess the safety and efficacy of different surgical techniques in reoperation.
  • To determine long-term results including normotension and complication rates.

Main Methods:

  • Retrospective chart review of 43 patients undergoing repeat surgical intervention for recurrent aortic coarctation (1976-1993).

  • Analysis of initial surgical approaches (subclavian flap aortoplasty, end-to-end anastomosis) and reoperation strategies.
  • Inclusion of data on concomitant congenital cardiac anomalies and transverse arch hypoplasia.

    • Main Results:

    • Patch aortoplasty was the primary reoperation technique for 86% of patients.
    • 26% of patients required transverse arch augmentation under hypothermic circulatory arrest.
    • Three patients needed a second reoperation, treated with tube graft interposition.

    Conclusions:

    • Surgical reintervention for recurrent coarctation is safe, with no reported ischemic spinal injuries.
    • Transverse arch augmentation was associated with no further surgical intervention needs.
    • Reoperation mortality was 7%, comparable to primary coarctation repair, with 57% of patients normotensive at follow-up.
