Infants with anomalous left coronary artery from the pulmonary artery (ALCAPA) usually do well for a short period then gradually become fussy and irritable. Typically, they may display pallor, irritability, and diaphoresis after feeding, which are often attributed to colic.

Signs and symptoms of congestive heart failure, including tachypnea, tachycardia, diaphoresis, and poor feeding, eventually ensue, leading to poor weight gain. Usually no obvious evidence of a systemic illness is noted.

In rare instances, children outgrow these symptoms and gradually become asymptomatic, although periodic dyspnea, angina pectoris, syncope, or sudden death may still occur in adulthood.
