RESUMO
Pseudoaneurysm of the right ventricular outflow tract (RVOT), post repair for tetralogy of Fallot (TOF), is a rare occurrence with few cases reported in literature. TOF with single pulmonary artery is in itself a rare occurrence. RVOT pseudoaneurysm in a case of TOF with single pulmonary artery has not been reported to the best of our knowledge. RVOT pseudoaneurysm is a catastrophic complication which has very few symptoms and has to be picked up early to avoid dire consequences. We have reported such a rare occurrence to highlight the importance of looking out for such complications in rare presentations where anatomy is altered.
