Pentalogy of Fallot (POF) is a rare variant of the more common tetralogy of Fallot (TOF), characterized by the classic features of TOF along with an additional congenital cardiac lesion such as an atrial septal defect (ASD) or patent ductus arteriosus (PDA). Here, we pre­sent a case of POF presenting as acyanotic congenital heart disease in a 5-week-old infant. The patient initial­ly presented with symptoms suggestive of respiratory infection but was diagnosed with bronchopneumonia complicated by congestive cardiac failure. Further in­vestigations revealed the presence of POF, which in­cludes right ventricular outflow tract obstruction, ven­tricular septal defect overriding the aorta, pulmonary stenosis, and an additional small ostium secundum ASD. This case highlights the importance of consider­ing POF in the differential diagnosis of acyanotic con­genital heart diseases and emphasizes the necessity for timely diagnosis and appropriate management to improve patient outcomes.
