Pulmonary Shunt

Atrial septal defect causes left to right shunt due to the high compliance of the right atrium and the difference in pressure between the two atria. Secondary to this mechanism, the pressure in the pulmonary circulation is increased.

Vivien Thomas was a key player in pioneering the anastomosis of the subclavian artery to the pulmonary artery.The surgical work he performed with Alfred Blalock paved the way for the successful outcome of the Blalock-Taussig shunt. Unable to attend college for lack of money, Thomas began as Dr. Blalock's lab assistant, but his skill in designing surgical tools and inventing surgical techniques made him invaluable. His work was unrecognized until late in his life because he was…
