Abstract:
One hundred and seven cases of tetralogy of Fallot (TOF) were surgically corrected in this institute in the period from Jan 1983 to Dec 1989. Adequate corrective procedures were performed in 106 cases and aorto-pulmo-nary shunt with 1.2 Dacron tube in one. The corrective procedures employed included simple intracardiac repair in 18, subpulmonary RV outflow patch in 50, transannular RV outflow patch in 37, and RV-PA coronary conduit in 1 because of anomalous right coronary artery. The operative mortality rate was 13% , and the main complication was low cardiac output syndrome (LCOS) , which occurred in 26 cases (24%) .It was found that the predisposing factors of LOS after corrective surgery for TOF were serious clinical manifestations of the patient before operation, and residual right ventricular outflow tract obstruction due to improper repair of the right ventricular outflow tract, which were fatal in some cases.
