Rannsókn þessi er tileinkuð Kvenfélaginu
Hringnum, sem um árabil hefur stutt
Bamaspítala Hringsins með framlögum og
gjöfum. Omskoðunartæki það sem notað var
í þessari rannsókn var þeirra gjöf og án þess

SUMMARY
Twelve patients with left-to-right shunt at the
atrial level (11 with atrial septal defect (ASD)
and one with partial anomalous pulmonary venous
connection (PAPVC)) underwent diagnostic cardiac
catheterization (cath) after quantification of the
shunt had been estimated using Doppler technique.
The pulmonary blood flow and the systemic blood
flow was measured during the cath using the Fick
method. The results of the Doppler technique and
the cath method were compared.
The pulmonary blood flow (Qp) by Doppler ranged
from 4.4 - 9.3 (median 6.7) l/min/m2 and 4.1 -
8.9 (median 6.7) l/min/m2 by the Fick method.
Correlation (Spearman rank): r = 0.85 and p <
0.01. The systemic blood flow (Qs) using Doppler
ranged from 2.6 - 4.8 (median 3.8) l/min/m2
and 3.0 - 5.1 (median 3.7) l/min/m2 by the Fick
method. Correlation: r = 0.87, p < 0.01. When
Qp/Qs ratio using these two methods was compared
the r = 0.83, p < 0.01.
We conclude that the Doppler method is an
effective and reliable method of measuring the size
of left-to-right shunt at the atrial level is this group
of patients.
