A 2-month-old baby is admitted to our unit for bronchiolitis. Due to the infant's prolonged symptoms with predominant feeding difficulties and because of a heart murmur noted on auscultation, cardiac ultrasound is performed, resulting in the diagnosis of ALCAPA syndrome (Anomalous Left Coronary Artery from Pulmonary Artery). ALCAPA is a rare but severe cardiac malformation, with early diagnosis and treatment being key to a good prognosis. Bronchiolitis can provoke heart failure, whereas clinical features of heart failure may mimic bronchiolitis. This clinical case underlines the need for performing a complete clinical examination, along with oriented diagnostic investigations, when confronted with a baby suffering from a respiratory condition whose severity or evolution appears unusual.
