| Abstract |
|
The operative results of 50 cases who underwent arterial switch operation from January, 1986 to March, 1991 were evaluated. The results were summarized as follows ;
1) Three main combined cardiac defects of ASO cases were PDA(60%), VSD(56%) and ASD(46%), and most common type of VSD was perimembranous(64.3%) and most frequent pattern of coronary artery was usual pattern of TGA (84%).
2) The average mortality rate was 44.0%, which comprised 54.5% in TGA with IVS group including two late deaths, 40.0% in TGA with VSD group and 0% in DORV (Taussig-Bing type) group.
3) The annual mortality rate showed decreasing tendency ; 100% in 1986, 60%, in 1987, 66.7% in 1988, 40% in 1989, and 34.8% after 1990.
4) During short term follow-up period, survivors showed relatively good postoperative status including LV contractility without significant RVOT or LVOT obstruction, in spite of several complications. |
