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.
The procedure that these two men created, known as the Blalock–Hanlon procedure, was a new concept termed atrial septectomy. This procedure had been experimented on the right atrium of dogs before Dr. Blalock and Dr. Hanlon had performed it on humans. [4]
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 can also be performed, usually with a cardiac catheter instead of surgery, to enlarge a natural connection between the heart's upper chambers (atria). This will allow for the oxygen-rich and oxygen-poor blood to mix, resulting in improved oxygen delivery to the baby's body.
Balloon septostomy is the widening of a foramen ovale, patent foramen ovale (PFO), or atrial septal defect (ASD) via cardiac catheterization (heart cath) using a balloon catheter. This procedure allows a greater amount of oxygenated blood to enter the systemic circulation in some cases of cyanotic congenital heart defect ( CHD ).

Among them was an open repair of an atrial septal defect using hypothermia, inflow occlusion and direct vision in a 5-year-old child performed in 1952 by Lewis and Tauffe. C. Walter Lillihei used cross-circulation between a boy and his father to maintain perfusion while performing a direct repair of a ventricular septal defect in a 4-year-old ...
Blue baby syndrome, Atrial septostomy Vivien Theodore Thomas (August 29, 1910 [ 1 ] – November 26, 1985) [ 2 ] was an American laboratory supervisor who, in the 1940s, played a major role in developing a procedure now called the Blalock–Thomas–Taussig shunt used to treat blue baby syndrome (now known as cyanotic heart disease) along with ...
