Bicuspid aortic valve with critical coarctation of the aorta: singleor two-stage operation?
Abstract
Background: A bicuspid aortic valve (BAV) with critical coarctation of the aorta (CoA) is a rare but dangerous congenital cardiac malformation. The aim of this study was to compare the benefits of a single- versus two-stage operation for patients of BAV with CoA.
Methods: We retrospectively evaluated 20 patients of BAV and CoA who underwent surgery from 2000 to 2016 in our center. Eight patients underwent a single-stage procedure through a median sternotomy approach, while 12 patients underwent two-stage operation.
Results: The patients’ baseline characteristics were similar between the two groups, and the overall mortality rate was 0%. No significant differences were found in the postoperative pressure gradient (P=0.64), use of implants (P=0.81), reoperation for bleeding, phrenic nerve injury, blood transfusion (P=1.00), or thromboembolic events between the two groups. However, patients in the single-stage group sustained less surgical trauma and ICU stay hours (P<0.01) than those in the two-stage group.
Conclusions: Performance of a single-stage operation was feasible for patients of BAV with CoA. It was a safe and optimal choice with less surgical trauma compared with a two-stage operation.
