Arterial switch operation
Arterial switch operation is a surgical procedure used to correct transposition of the great arteries (TGA), a congenital heart defect. The operation involves the repositioning of the pulmonary artery and the aorta to their correct anatomical locations. This procedure is typically performed within the first few weeks of life.
History[edit | edit source]
The arterial switch operation was first described by Adib Jatene in 1975. Prior to this, the Mustard procedure and the Senning procedure were the standard treatments for TGA. However, these procedures did not correct the underlying anatomical problem and often led to long-term complications.
Procedure[edit | edit source]
The arterial switch operation involves several steps. First, the coronary arteries are detached from the aorta and reattached to the new aorta (previously the pulmonary artery). Then, the pulmonary artery is moved to the front and the aorta is moved to the back. The procedure also involves the closure of any associated ventricular septal defects (VSDs).
Outcomes[edit | edit source]
The arterial switch operation has a high success rate, with survival rates of over 90% at 10 years. However, potential complications can include coronary artery problems, heart valve issues, and arrhythmias. Long-term follow-up is necessary to monitor for these potential complications.
