Clinicoradiological Correlation Atik & Barbero-Marcial Pulmonary stenosis after Barbero-Marcial technique in truncus arteriosus Arq Bras Cardiol 2020; 115(1Suppl.1):37-39 This is an open-access article distributed under the terms of the Creative Commons Attribution License The preservation of the narrower outflow tract, as observed in the case presented herein, brings to mind the occurrence and discussion of how it should happen in similar operated patients, as most commonly in the Tetralogy of Fallot. This fact could occur more frequently, as long as the surgeon better preserved the RV outflow tract in a narrower area, allowing the pulmonary stenosis evolution to predominate 1.

Reference over valve regurgitation. This preference stems from the fact that the volume overload myocardial lesion is more harmful than pulmonary stenosis, which is caused more often by monocusp calcification. Ideally, these patients should always be adequately monitored, aiming to preserve the recommended condition for a more favorable evolution in the longer term. 39
