Hemodynamics of 12 patients with tetralogy of Fallot were monitored during
the first 72 hours after surgical repair. Total immediate repair in 5
patients was followed after 24 hours by a greater decrease in cardiac index
than that observed in the group of 4 patients with previous palliative
shunt (minus 25 plus or minus 6 vs. minus 1 plus or minus 7 per cent, p
smaller than 0.025). This difference disappeared after 48 hours, and the
short-term follow-up periods of these two groups were equally smooth. Six
patients with pulmonary stenosis requiring the placement of an outflow
patch had higher right ventricular filling pressures (after 24 hours 13.8
vs. 10.8 mm. Hg, p smaller than 0.025; 2 to 4 weeks later 9.6 vs. 5.5 mm.
Hg, p smaller than 0.05), suggestive of a persistent right ventricular
depression. This ventricular depression must be attributed to the induced
pulmonary insufficiency and to the presence of akinetic areas. Both these
factors should therefore be carefully minimized during the surgical
procedure.
