Sažetak
The magnitude of left-to-right shunt in 55 children with isolated congenital heart disease (atrial septal defect or ventricular septal defect /muscular and perimembranous/) was estimated by two methods: 1. radionuclide quantification and 2. Doppler echocardiography (Flow (L/min)=mean velocity x area x ejection time x heart rate). We found small differences between the magnitude of left-to-right shunt obtained with Doppler echocardiography and radioangioscintigraphy for whole group of patients (n=55 pts, -11, 42% to 12, 04%), as well as, for a subgroups of ASD (n=24 pts, -12, 49% to 12, 19%) and VSD (n=31 pts, -10, 69% to 12, 23%). These results implicate that Doppler echocardiography is sufficiently accurate method for clinical estimation of the Qp/Qs ratio in isolated congenital heart disease with left-to-right shunt, in comparision in radioangioscintigraphy.
