Surgical correction of Tetralogy of Fallot / 대한흉부외과학회지

ABSTRACT

BACKGROUND: The authors studied factors that affected operative mortality and clinical course by analysis of 98 patients who had underwent total correction of TOF at department of thoracic surgery, Pusan Paik hospital from Sept, 1985 to Aug, 1996 to predict the outcome of operation and improve the result of total correction. MATERIALS AND METHODS: To analyse the factors that affect operative mortality, patients were divided into two groups, non-survivor (group I) and survivor (group II), compared body surface area (BSA), aortic clamping time (ACT), total bypass time (TBT), preoperative PRV/LV, postoperative PRV/LV, operation method between them. These same patients were also divided into two groups, group A (non-survivor or severe complication group) and B (survivor and only mild complication group), comparing the same items. RESULTS: There were statistical differences between group I and II about postoperative PRV/LV as 0.67+/-0.13, 0.46+/-0.15. There were statistical differences between group A and B about postoperative PRV/LV as 0.62+/-0.12, 0.44+/-0.15. Transventricular cases were predominant in group A, transatrial cases in group B (p<0.01). CONCLUSIONS: We suggested that the operative results of TOF were better in cases of lower postoperative PRV/LV and transatrial approach.
