Background : Pulmonary valve replacement has proven benefits in patients with congenital heart disease. Although the choice of
replacement valve remains controversial, bioprosthetic valve has an excellent short-term and mid-term durability, no limit in
availability and readily to use, and no requirement for anticoagulation.
Objective : The present study aimed to describe our surgical technique for pulmonary valve replacement with bioprosthetic valve
and to report early clinical outcomes.
Materials and Methods : All patients from January 2016 to July 2018: 11 patients underwent pulmonary valve replacement with
bioprosthetic valve for congenital heart disease and were retrospectively reviewed. Pre-operative and postoperative data were
compared.
Results : Mean age was 30.91+12.29 years. Ten (90.91%) patient had prior cardiac surgery. All patients were classified in NYHA class
II (90.91%) and III (9.09%). Mean follow-up period was 9.34+4.78 months. Mean ICU stays and hospital stays were 1.63+0.50 and
6.54+4.01 days, respectively. No complications or mortality occurred. All patients’ NYHA classifications were improved to class I
(100%). Pre-operative LVEF and postoperative % LVEF were similar 59+9.41 vs. 60.36+9.42 (p = 0.358). There was no significant
difference in pre-operative and postoperative QRS duration 149+27.07 vs. 146.36+28.27 ms, (p = 0.616).
Conclusion : Pulmonary valve replacement with bioprosthetic valve with our current surgical technique is simple, safe, reproducible,
and has excellent clinical outcomes.
