OBJECTIVES: This study aimed to assess mitral valve function after repair of ventricular septal defect (VSD) combined with mitral regurgitation (MR) in the mid-term follow-up period, to evaluate the clinical utility of simultaneous mitral valve repair (MVR).
METHODS: From June 2005 to March 2014, 60 patients with VSD and MR underwent surgical treatment. After performing propensity score analysis (1:1) for the entire sample, 46 patients were selected and divided into 2 groups: those with VSD closure and MVR - 23 patients and those with VSD closure without mitral valve intervention - 23 patients. The follow-up period - 32 (28;40) months.
RESULTS: There was no postoperative mortality in either group. There was no significant difference in the duration of the postoperative period between groups. Mean cardiopulmonary bypass time and aortic cross-clamping time were significantly longer in the 'VSD + MVR' group (cardiopulmonary bypass, P=0.023; aortic cross-clamp, P< 0.001). There was no significant difference in regurgitation area (P=0.30) and MR grade (P= 0.76) between groups postoperatively. There was no significant difference in freedom from MR ≥ 2+ between groups (log-rank test, P= 0.28). The only significant risk factor for recurrent MR ≥ 2+ during the follow-up period was mild residual MR in the early postoperative period ( P=0.037).
CONCLUSIONS: In infants with VSD combined with MR, simultaneous MVR has no benefits simultaneous MVR provided no advantage over that of isolated VSD closure. We found that the presence of mild residual MR in the early postoperative period predisposes the development of MR ≥ 2+ in follow-up period.
The Ross procedure has emerged as an attractive option for aortic valve replacement in children and young adults. This work represents immediate postoperative period results and long term outcome after Ross procedure among the pediatric population in the single center experience. The main part of a material is submitted by the statistical analysis of risk factors in the early postoperative period within more than 5 years postoperative analysis of long term condition.
Hypoplastic left heart syndrome is a congenital heart disease that affects the normal blood flow through the heart and it characterized by a critical underdevelopment of the left heart. Hypoplastic left heart syndrome is 1.43.8% among all congenital heart defects and 16% among critical congenital heart disease. Mortality in large cardiac surgery centers currently does not exceed 15%. However, mortality among patients with low body mass is up to 51% after the first stage of palliative surgery. In our clinical case, we describe hemodynamic surgery in neonatal with left-heart hypoplasia syndrome and low body weight (Norwood procedure with Sano shunt), postoperative case management inter-stage period and bidirectional cavopulmonary anastomosis procedure (second stage of hemodynamic correction).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
