Abstract:
Objective To explore the early results of Ozaki operation in children with aortic regurgitation. Methods We retrospectively analyzed the clinical data of 15 patients with aortic regurgitation who received the Ozaki operation in our hospital from April 2017 to July 2019. There were 11 males and 4 females with an average operation age of 10.7±3.7 years. Besides preoperative evaluation, aortic regurgitation and cardiac function were evaluated on 1 day, 1 week, 1 month, 3 months, and 6-12 months after surgery. Results In 14 (93.3%) patients , the aortic valve leaflets functioned well on 1 day, 1 month, 3 months, and 6-12 months, and the regurgitation grade was Ⅰ-Ⅱ, which was improved than before (P=0.001). The cardiac function of children recovered quickly after operation. There was no statistical difference in ejection fraction on 1 day, 1 month, 3 months, and 6-12 months after operation (P>0.05). No children died, and no other clinical event was found. Conclusion The Ozaki technique of reconstructing a tricuspid aortic valve leaflet for the treatment of severe aortic regurgitation in children is effective in short term, and the persistence of its valve function remains to be determined in the long-term follow-up.
