Abstract

Coarctation of the aorta (AoCo) accounts for 6-10% of congenital heart diseases in infants. We analysed echocardiographic findings of patients operated on for AoCo in the University Hospital for Children in Riga during the first year of life to evaluate the long-term findings. Fifty-nine children underwent surgical correction of AoCo at the age of 55 ± 61 days. The methods of surgical correction were anastomosis end-to-end (ETE) in 29% (n = 17), subclavian flap aortoplasty (SFA) in 64% (n = 38) and extended anastomosis end-to-end (EETE) in 7% (n = 4). Recoarctation developed in 15 patients (25%) with no difference between surgical techniques (P > 0.05). The recoarcation patients had left ventricle hypertrophy (left ventricle mass index (LVMi) 76 ± 19 g/m2.7) normalising after angioplasty (LVMi 42 ± 7 g/m2.7). Patients with recoarctation had a decreased pulsed wave (PW) Doppler systolic/diastolic ratio in abdominal aorta 2.3 ± 0.4 versus patients without recoarctation 5.3 ± 1.2 and the control group 6.3 ± 1.4 (P < 0.05). A high incidence of recoarctation exists in patients operated on for AoCo as small infants. Life-long surveillance is required to monitor and to intervene in a timely way. Supplementation of the echocardiographic protocol with an evaluation of PW Doppler flow pattern in abdominal aorta can provide additional information about the presence of obstruction.
