- Factors associated with moderate or severe left atrioventricular valve regurgitation within 30 days of repair of incomplete atrioventricular septal defect Marcelo Felipe Kozak Ana Carolina Leiroz Ferreira Botelho Maisano Kozak Carlos Henrique De Marchi Moacyr Fernandes de Godoy Ulisses Alexandre Croti Airton Camacho Moscardini Medicina Congenital Heart Defects Postoperative Period Mitral Valve Insufficiency Endocardial Cushion Defects Introduction: Left atrioventricular valve regurgitation is the most concerning residual lesion after surgical correction of atrioventricular septal defect. Objective: To determine factors associated with moderate or greater left atrioventricular valve regurgitation within 30 days of surgical repair of incomplete atrioventricular septal defect. Methods: We assessed the results of 51 consecutive patients 14 years-old and younger presenting with incomplete atrioven - tricular septal defect that were operated on at our practice be - tween 2002 and 2010. The following variables were considered: age, weight, absence of Down syndrome, grade of preoperative left atrioventricular valve regurgitation, abnormalities on the left atrioventricular valve and the use of annuloplasty. The me - dian age was 4.1 years; the median weight was 13.4 Kg; 37.2% had Down syndrome. At the time of preoperative evaluation, there were 23 cases with moderate or greater left atrioven - tricular valve regurgitation (45.1%). Abnormalities on the left atrioventricular valve were found in 17.6%; annuloplasty was performed in 21.6%. Results: At the time of postoperative evaluation, there were 12 cases with moderate or greater left atrioventricular valve regurgitation (23.5%). The variation between pre- and post - operative grades of left atrioventricular valve regurgitation of patients with atrioventricular valve malformation did not reach significance ( P =0.26), unlike patients without such abnormali - ties ( P =0.016). During univariate analysis, only absence of Down syndrome was statistically significant ( P =0.02). However, after a multivariate analysis, none of the factors reached significance. Conclusion: None of the factors studied was determinant of a moderate or greater left atrioventricular valve regurgitation within the first 30 days of repair of incomplete atrioventricular septal defect in the sample. Patients without abnormalities on the left atrioventricular valve benefit more of the operation. 2015 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941897010 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.2 Vol.30
