Abstract

We show a brief report of two common arterial trunk cases (CAT) with different arrhythmias and discuss anatomy, clinical and diagnostic management. The burden of volume and pressure overload of this cardiac malfor-mation may predispose to different types of arrhythmia before and after surgical repair. Because of labile hemodynamic state in this group of patients, prompt diagnosis of any arrhythmia is mandatory as the devastating factor on prognosis. The first patient with a diagnosis of CAT Type II Collett and Edwards (CE) had a particular history with HIV seropositive mother assuming antiretroviral therapy during pregnancy, who presented hyper-bilirubinemia and liver dysfunction at birth, and re-entry atrial tachycardia after repair. The second patient had CAT Type I CE with a partial anomalous venous connection of left superior pulmonary vein and uncommon type of atrial tachycardia with dual AV nodal physiology. © 2021, Tech Science Press.
