[Cardio-hemodynamics in patients with Fallot's tetrad during operative and early postoperative period]

Studies of hemodynamics in 22 patients with Fallot's tetrade in the operative and early post-operative periods were analysed. The stroke and cardiac output were studied in all patients as well as the pressure in the cavities of the heart with subsequent calculation of coefficients PRV/PLV, PPA/PRV, and P.P-Q diagrams were constructed to characterize the pathophysiological processes in the heart ventricles. Correction of the anomaly was considered adequate in PRV/PLV less than or equal to 0.6. Coefficient PRV/PLV greater than 0.6 calls for additional analysis for the purpose of identifying residual stenosis or blood dumping at the level of the interventricular septum.
