Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). [ 1 ] [ 2 ] Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene , who was the first to use it successfully.
The high chance of developing arrhythmias results in up to 25% of patients who have undergone a Senning or Mustard procedure having a pacemaker by adulthood. [ 5 ] Long-term studies have disclosed that although from the functional capacity standpoint the Senning and the Mustard operation are similar, there is a higher risk of sinus node disease ...
In some cases, it is not possible to perform an arterial switch, either because of late diagnosis, sepsis, or a contraindicative coronary artery pattern. In the case of sepsis or late diagnosis, a delayed Arterial Switch can sometimes be made possible by PAB, which may also require a concomitant construction of an aortic-to-pulmonary artery ...
This is the most common surgery done to correct dextro-TGA, and is considered the definitive treatment. The atrial switch operation is an alternative surgical option when the arterial switch is not feasible due to the particular coronary artery anatomy. This operation creates a tunnel (baffle) between the heart's two upper chambers (atria). [2]
This surgery had not been possible prior to 1975 because of difficulty with re-implanting coronary arteries which perfuse the actual heart muscle itself , and even after it was first performed the excellent results from the Mustard operation meant that it was a long time before the Jatene procedure took over.
Atrial switch is a heart operation performed to treat dextro-Transposition of the great arteries. [ 1 ] [ 2 ] It involves the construction of an atrial baffle which redirects the blood coming into the atria to restore the connection between systemic and pulmonary circulation.
The LeCompte maneuver is a technique used in open heart surgery, primarily on infants and children. The maneuver entails cutting the main pulmonary artery and moving it anterior to the aorta before reattaching the pulmonary artery during the following reconstruction of the great vessels.
Diagram of the human heart. Several adaptations of the Ross procedure have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft.
