ABSTRACT We examined 97 patients aged 14 days - 21 years with coarctation of the aorta (CA) and studied effect of high pressure and pressure gradient in the region of CA (DeltaP(CA)) on cardiac pump function and reserve capacity of the left ventricle. Children with left ventricular (LV) ejection fraction (EF) below 30% (n=24) comprised group 1, patients with LVEF 30 - 45% (n=55) - group 2, and patients with LVEF above 45% - group 3. Four group 1 patients had signs of fibroelastosis of the left ventricle, 3 of them were operated before age of 3 months, 1 - at the age of 5 months. The latter patient died in 2 months after surgery. In 3 patients LVEF rose after surgery and completely normalized in remote period. High DeltaP(CA) affected predominantly contractile left ventricular function in newborns. Significant improvement of LVEF was observed in patients operated upon in the age before 3 months.
