Clinical Study to Individual Treatment for Major Aortopulmonary Collaterals of Tetralogy of Fallot

Abstract

Objectives. To build a guideline for the individual treatment of Tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) and tentatively establish the occlusion index of MAPCAs. Methods. According to the diameter of the aortopulmonary collaterals (R: Mm) and the bodyweight of the children (weight: Kg), K= ((∑R2)/Wt) was set as the occlusion index of TOF with MAPCAs. A retrospective study was initially performed in 171 patients who suffered from TOF with MAPCAs and underwent cardiac malformation repair to investigate the intervals of the K value: K≥2, 1 <0.05) in patients with 1
