EARLY AND MID-TERM OUTCOMES OF AORTIC VALVE NEOCUSPIDIZATION FOR CONGENITAL DISEASE IN THE PEDIATRIC POPULATION

Aim: In this study, we scrutinized the early and mid-term results of aortic valve neocuspidization in the pediatric population with different aortic valve diseases. Methods: From January 2015 to December 2019, aortic valve neocuspidization was performed for 10 patients. The mean age was 15,4 ± 6,6 years. There was one patient with aortic stenosis, 3 patients with aortic regurgitation and 6 patients with mixed aortic valve disease. 7 patients had II type bicuspid valve, whereas 3 patients - bicuspid I type. All patients were males. Results: The mean follow-up was 1,8 ± 0,8 years. Preoperative echocardiography identified a peak pressure gradient average of 52,80 ± 33,94 mm Hg with aortic stenosis. There was neither conversion to a prosthetic aortic valve replacement nor hospital mortality. Postoperative echocardiography showed a peak pressure gradient average of 23,30 ± 16,03 mm Hg and 3 (30 %) patients experienced recurrent moderate aortic regurgitation/stenosis 5 years after surgery. Conclusions: The mid-term outcomes of aortic valve neocuspidization were satisfactory in children with different aortic valve diseases. However, further long-term data should be studied to acknowledge the obtained current results.
