STUDIES ON PRE- AND POSTOPERATIVE HEMODYNAMICS BY MEANS OF HEMODYNAMOGRAMS IN CONGENITAL HEART DISEASES

Hemodynamics in congenital heart diseases was studied in 111 cases before and after operation by means of hemodynamograms with 12 parameters (CI, PR, MAP, PAP, PWP, RAP, TPR, PAR, LVSWI, RVSWI, LW, RW). These data were measured and calculated pre- and postoperatively by the Swan-Ganz catheter and the Cardiac output computer.
The hemodynamograms were classified into four patterns (1. Normal pattern, 2. Star pattern, 3. Right dominant pattern and 4. Left dominant pattern). The pre- and postoperative hemodynamograms gave the following results :
1. Normal pattern meant good cardiac function.
2. Star pattern meant pulmonary hypertension.
3. Right dominant pattern meant right heart failure or LOS.
4. Left dominant pattern meant high cardiac output, suggesting good cardiac function.
Hemodynamograms proved to reflect accurately the characteristics of the pre- and postoperative hemodynamics of congenital heart diseases and to be useful to evaluate the choice of operation and the postoperative management.
