Mengubah Hidup dengan Operasi Suis Arteri (ASO))

The Arterial Switch Operation (ASO) is a crucial surgical procedure performed to correct a congenital heart defect known as dextro-transposition of the great arteries (D-TGA). In D-TGA, the two main arteries of the heart—the aorta and the pulmonary artery—are improperly positioned. This results in oxygen-poor blood being circulated to the body instead of to the lungs, and oxygen-rich blood being circulated back to the lungs instead of to the body, which can be life-threatening if left untreated.

The ASO involves a series of intricate steps where the surgeon detaches the aorta and the pulmonary artery from their transposed positions and reattaches them to their proper locations. This reconnection ensures that oxygen-rich blood from the lungs is sent out to the body through the aorta, and oxygen-poor blood is sent to the lungs through the pulmonary artery. Additionally, the coronary arteries, which supply blood to the heart muscle itself, are also re-implanted into the newly positioned aorta.

Typically performed within the first few weeks after birth, the ASO is a lifesaving procedure that allows children with D-TGA to have normal heart function, leading to a healthy life with few restrictions. The success rate for the surgery is high, and it effectively addresses the circulatory mismatch, allowing proper oxygenation of the body.
