The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958.
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.
It is similar to the previous atrial baffle used with a Senning procedure, the primary difference being that the Mustard uses a graft made of Dacron or pericardium, while the Senning uses native heart tissue. The procedure was developed to treat transposition of the great vessels, eponymously known as blue baby syndrome.
A baffle is a surgically created tunnel or wall within the heart or major blood vessels used to redirect the flow of blood. [1] They are used in some types of heart abnormalities that a child is born with known as congenital heart defects. Baffles are usually constructed, at least in part, from a person's own heart tissue, while other methods ...
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]
The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings that the arterial switch improved upon, in particular a reduced kinking of the coronary arteries when combined with the LeCompte maneuver. The end result is that the aorta is repositioned behind the pulmonary arteries, functionally ...
A balloon atrial septostomy is performed with a balloon catheter, which is inserted into a patent foramen ovale (PFO), or atrial septal defect (ASD) and inflated to enlarge the opening in the atrial septum; this creates a shunt which allows a larger amount of oxygenated ("red") blood to enter the systemic circulation.
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.
