Abstract
Pulmonary arterial hypertension (PAH) in children with congenital left-to-right shunt (APAH - CHD) is a very common complication. The question of the indications forthe cardiac surgery repair of the left-to-right shunt is controversial and has no one solution. In Scientific Centre of Paediatric and Paediatric Surgery (SCP and PS) of the Ministry of Health of the Republic of Kazakhstan since 2011 department of the cardiac surgery and intervention cardiology treats over 120 children with APAH - CHD. The most part of the patients is older 6-month-old.However, the guidelines for ventricular septal defect (VSD), patent ductus arteriosus (PDA) and atrial septal defect (ASD) are not define the precise moment of the surgery repair. Early terms for these types of CHD agreed to be under 2 years old.Aforementioned, we studied the evidence of Echocardiography parameters in predicting PH in children with congenital left-to-right shunting on the early age. For that we took the Echo reports of 26 children from 60 to 186 days of life with congenital left-to-right shunting, under suspicious of being complicated with pulmonary arterial hypertension. For the main objective of our study we assessed the volume overload with measure of Qp/Qs index, peak and mean velocity and pressure gradients of the tricuspid regurgitation (TR) and on the pulmonary artery (PA) systolic flow. Size of the aorta (Ao) and PA.16 children (group 1) were operated at the age of 11.5±4.2 months old, while other 10 (group 2) were operated at the age of 3.6±1.3 years old. 19 children were with VSD, and 8 with PDA. Children with the high EDI and Qp/Qs ratio show more tendency for developing PAH in postoperative period.
