Abstract
Total correction for Tetralogy of Fallot was performed in 100 consecutive patinents from July 1978 to December 1980, with 2 hospital 1 late death. Preoperative angiographic findings were useful for the evaluation of severity of Tetralogy of Fallot. From the RVgraphy, we caluculated PA index as follows; PA index=(r-PA diameter)^2 + (l-PA diameter)^2/4ヂSA The incidence of LOS was significantly higher in one group (preoperative PA index<200) than another group (preoperative PA index<200). The was a good correlation between preoprative PA index and cardiac index at 24 hour after repair. C.I.=0.0043×PA index+1.9 (r=0.69) 1 month after total correction, PA index increasing significantly especially in hypoplastic group, and there were no significant differences. We consider that PA index can be a good indicator to estimate the development of pulmonary pulmonary artery left heart.
