Alfred Blalock

Alfred Blalock was a pioneering American surgeon renowned for developing life-saving heart surgery techniques. He is best known for creating the "Blalock-Taussig shunt," a procedure that improved blood flow in babies with tetralogy of Fallot, a congenital heart defect causing insufficient oxygen in the blood. His work revolutionized cardiac surgery and dramatically increased survival rates for children born with complex heart conditions. Blalock’s innovative approach and dedication to medical progress made him a key figure in pediatric cardiology and surgical medicine.
