Born 24 May 1903; died 26 Mar 1988 at age 84.

#Canadian #heart #surgeon, noted chiefly for his development, in 1950, of a surgical procedure for correction of impaired #coronary #circulation.

In the #Vineberg #operation one end of an artery in the chest, called the #InternalMammaryArtery, is freed up. The side branches to the artery, like tributaries flowing off a river, are cut to allow blood to flow freely from them. The artery then is snaked under the surface of the #heart muscle, and each time the heart beats, blood from the branches oozes into the heart muscle, nourishing it. Over time new #vessels grow and supply blood to the #myocardium. The first clinical procedure was carried out at the Royal Victoria Hospital in #Montreal in 1950. Modern #BypassSurgery pre-empted it in the 1960s.
