Early outcome of tetralogy of Fallot repair in the (original) (raw)

Abstract Background: Traditional use of trans-annular patch (TAP) to release right ventricular outflow tract (RVOT) obstruction during tetralogy of Fallot (TOF) repair may lead to a harmful pulmonary regurgitation. Different approaches have been used to release RVOT obstruction and spare the pulmonary valve (PV) function. In this study, we aim to evaluate the post-operative course of patients who had TOF repair in the current era that emphasizes on protective strategy of releasing RVOT obstruction and preserving PV function. Methods: A retrospective study of all TOF cases repaired in our institute between March 2002 and December 2007 was conducted. Cases were classified into two groups; group I included patients that had a TAP, while group II included cases that had simple TOF repair without TAP. Group I was subdivided into two groups, group (A) which include patients who had TAP without a valve. Group (B) includes those who had TAP with a monocuspid valve (Contegra). We compared po...
