Abstract

Among 160 patients of Tetralogy of Fallot were performed complet correction, preservation of pulmonary valve was carried out in 109 patients (68.1%). PTFE 0.1 mm Monocurp was indicated in 51 cases (31.9%). Pulmonary artery diameter was different between two groups (13.36 and 11.93, p=0.008). Z value was also different (-1.83 and - 2.85, p< 0.001 ) . The ideal Z value for pulmonary valve preservation is >_ -3 . PTFE Monocusp should be performed in case Z value < -3 to avoid pulmonary artery gradient (27.72 and 18.25 , p=0.009). Z value >_3 was used to indicate the pulmonary valve preservation in Tetralogy correction at University Hospital - Ho chi Minh city with the rate of 0.77 and RR ratio is 2.09
