Abstract:

Objective To investigate the clinical application of aortic valve repair in pediatric aortic valve disease. Methods The clinical data of 83 children undergoing aortic valve repair were analysed. Patients aged between 4 months old and 11 years old, with the mean age of (3.6±5.0) years old. Patients were evaluated by ultrasound before operation, and single aortic insufficient was found in 24 patients, single aortic stenosis in 26 patients, and aortic insufficient combined with aortic stenosis in 33 patients. The repair techniques included commissurotomy (n=26), resuspension of commissures (n=27), pericardial patch cusp extension (n=15), raphe excision (n=12), cusp plication (n=6) and annuloplasty (n=2), and 50 patients required a combination of techniques. Results Patients were followed up for 3 months to 3 years. Two patients died, no patient was discharged with long-term treatment with anticoagulation drugs, and 2 patients underwent aortic valve replacement. Conclusion Aortic valve repair may yield favorable short-term and mid-term outcome in treatment of pediatric aortic valve disease, which can avoid reoperation and anticoagulation therapy. Aortic valve replacement can performed for reoperation during follow-up.
