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 ...
Including the anaesthesia and immediate post operative recovery, this surgery takes an average of approximately six to eight hours to complete. Some arterial switch recipients may present with post-operative pulmonary stenosis, which would then be repaired with angioplasty, pulmonary stenting via heart cath or median sternotomy, and/or xenograft.
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] After surgery: Lifelong follow-up care with a cardiologist is needed. Most infants who undergo surgery ...
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.
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.
Generally, if portions of cardiac wall are receiving less blood than normal, coronary angiography is indicated; then, lesions are identified and inform a decision to undergo PCI or CABG. [ 6 ] CABG is generally preferred over PCI when there is a significant burden of plaque on the coronary arteries, that is extensive and complex, due to ...
Atrial septostomy is a surgical procedure in which a small hole is created between the upper two chambers of the heart, the atria.This procedure is primarily used to palliate dextro-Transposition of the great arteries or d-TGA (often imprecisely called transposition of the great arteries), a life-threatening cyanotic congenital heart defect seen in infants.
