[The surgical treatment of aortic coarctation in infants in the 1st year of life with significantly decreased contractile function of the left ventricle]. / Khirurgicheskoe lechenie koarktatsii aorty u detei pervogo goda zhizni so znachitel'no snizhennoi sokratitel'noi funktsiei levogo zheludochka.

During the 1991-1998 yrs period there were operated on 20 patients with coarctation of aorta (CoA), aged up to 1 year old, in whom the ejaculatory fraction (EF) of left ventriculus (LI) was not exceeding 40%. All the patients were admitted to the hospital in the severe state of health, the end-diastolic (EDI) and the end-systolic (ESI) index constituting accordingly (144.2 +/- 47.2) and (84.2 +/- 34.7) ml/m2, EF LV--(34.2 +/- 4.7)%. After the operation one patient have died, the mortality was 5%. In three to eight days after the operation EDV have lowered by 15% on average, EF LV--have enhanced by 20%. In the majority of children in the late follow-up period EDI and ESI have lowered significantly, approximating the normal level, EF LV have normalized. The significant lowering of the LV function and the extremely severe state of the patient with CoA are not contraindications to the surgical intervention performance, vice versa, to such the patients the intensive therapy and the urgent operation conduction are indicated. The CoA demolition not only saves the child's life but fully normalizes the LV function in majority of the patients.
