Outcomes of Isolated Delayed Coarctation of the Aorta Surgery in Adults: Our 25-Year Experience

TL;DR

This study examines the outcomes of aortic coarctation surgery in adults over 25 years, highlighting the importance of long-term monitoring.

Contribution

The study provides long-term follow-up data on adult patients who underwent isolated coarctation of the aorta surgery.

Findings

Patients under 30 had a higher incidence of postoperative hypertension.

Recoarctation required surgery in 13 patients.

Preoperative hypertension and valve morphology were significant for additional surgeries.

Abstract

Background: The aim of this study was to evaluate the clinical outcomes of adult patients who underwent repair for delayed isolated coarctation of the aorta (CoA). In addition, we aimed to assess the immediate results of the interventions and long-term follow-up data. Methods: A total of 119 adult patients who were operated on for CoA and remained under follow-up during a 25-year study period were retrospectively analyzed. The pre-, intra-, and postoperative data of the patients were recorded. The surgical methods applied preoperatively and/or postoperatively were classified based on the primary issue as interventions involving the aorta and those not involving the aorta. Results: Of the patients, 81 were males and 28 were females with a mean age of 30.55 ± 10.84 (range: 18 to 67) years. The mean follow-up was 74.79 ± 61.71 (range: 0 to 271) months. A statistically significant difference was found between the presence of pre- and postoperative hypertension and the incidence of postoperative hypertension in patients under the age of 30 (p = 0.021 and p = 0.039, respectively). A total of 13 patients underwent surgery for recoarctation. The overall rate of additional cardiac surgery was 11.80%. The presence of preoperative hypertension and valve morphology (normal vs. bicuspid) were found to be statistically significant for the need for surgery before and after CoA repair. Conclusions: Patients with repaired CoA should be closely monitored due to the lifelong risk of developing complications. In particular, we recommend annual follow-up for patients with BAV.
