Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a life-threatening congenital condition. Explore its signs, diagnosis, and treatments.

What are the main causes of Anomalous Left Coronary Artery From The Pulmonary Artery (ALCAPA)?

A congenital defect occurs when the left coronary artery incorrectly connects to the pulmonary artery during fetal heart development.
Reduced oxygen supply to the heart muscle triggers ischemia and damage shortly after birth in affected infants.
Genetic or developmental abnormalities increase the likelihood of this rare but serious congenital heart defect.

Key symptoms of Anomalous Left Coronary Artery From The Pulmonary Artery (ALCAPA) to watch for

Infants may show difficulty feeding, excessive sweating, and rapid breathing within the first few months of life.
Heart murmurs, poor growth, and irritability can signal reduced cardiac function and oxygen supply.
Untreated cases may present with heart failure, arrhythmias, or sudden cardiac arrest during early childhood.

How can you prevent Anomalous Left Coronary Artery From The Pulmonary Artery (ALCAPA) effectively?

Early prenatal care and advanced fetal imaging help detect congenital heart defects before birth.
Genetic counseling may assist families with a history of congenital heart disease in understanding risks.
Prompt medical evaluation and surgical correction improve survival and long-term outcomes for affected children.
