TREATMENT RESULTS OF INFANTS WITH CRITICAL AORTIC STENOSIS

Abstract

For conducting a study to analyze the experience of surgical treatment and balloon valvuloplasty (BV) of critical aortic stenosis (AS) in newborns. Materials of 58 infants with AS for the period from 2006 to 2018 at the National Institute of Cardiovascular Surgery named after N.M. Amosov Ukraine were studied. The patients were divided into 2 groups. In the first group, 47 (81%) patients was done X-ray endovascular BV AS, in the second group, 11 (19%) patients was done surgical treatment. In the 1st group hospital mortality made up 6.8 % (n=4). In the 2nd group 4.5% of patients in postoperative period had complicated two-side pneumonia, sepsis, and patients died on the 15th and 20th days after procedure from increased respiratory and multiorgan failure. After ballon valvuloplasty we noted significant decrease of gradient on aortic valvule in patients of the 1st group and increased ejection fraction of left ventricule. Conclusion. Both surgical valvuloplasty and balloon valvuloplasty are effective methods of aortic stenosis treatment in infants with good results. The obtained results showed that balloon valvuloplasty can be acceptable alternative to surgical treatment in patients with expressed cardiac failure. But it has tendency to increases of aortic failure in remote period. The length of patients staying in hospital after balloon valvuloplasty is half shorter that patients with balloon valvuloplasty, which significantly reduces the expenses on treatment.
