Does interatrial communication affect post-operative course of children undergoing tetralogy of Fallot repair? Single centre retrospective cohort study: propensity score matching.

Introduction: During tetralogy of Fallot repair, leaving or even create an interatrial communication may facilitate post-operative course particularly with right ventricle restrictive physiology. The aim of our study is to assess the influence of atrial communication on post-operative course of tetralogy of Fallot repair.

Methods: Retrospectively, we studied all children who had tetralogy of Fallot repair (2003-2018).
