Surgical treatment of aortal stenoses n infants

The research included 28 patients. Valvular aortal stenosis was detected in 20 patients (71 %), subvalvular stenosis - in 4 patients, all with a tunnel type of stenosis (14 %), supravalvular stenosis - in 3 patients (10 %), Shone syndrome - in 1 patient (3 %). 23 patients (82.1 %) had circulation insufficiency symptoms, with 8 of them (28.57 %) suffering from II B-III class circulation insufficiency. Concomitant congenital heart diseases were detected in 22 patients (78.5 %), 10 of whom (35.7 %) were operated to repair the defects. 8 patients died, total lethality amounted to 28.5 %. 5 newborns underwent surgery, 2 of them died bringing lethality to 40 %. Reintervention was performed on 2 patients (7.1 %), the cause being aortal valve restenosis. Repairing aortal stenosis in infants, particularly in a neonatal period, is intricate and is accompanied with high lethality. The optimal surgical technique is still a controversial issue. Patients with valvular aortal stenosis receive either transluminal balloon valvuloplasty (TLBVP) of the aortal valve or open aortal commissurotomy. The first procedure is preferable for patients with severe circulation insufficiency or with ductus-dependent systemic circulation. Patients with sub- and supravalvular stenoses need complex reconstructive operations at an early age. Commonly occurring concomitant abnormalities complicate the course of follow-up and require additional surgical interventions.
