Mustard procedureA procedure developed by Dr Wm Mustard at the Hospital for Sick Children in Toronto for correcting transposition of the great vessels, a congenital cyanotic heart disease which, untreated, has a 20% one-year survival. About 80% of those treated with Mustard survive to age 20.
A baffle (artifical tunnel) is sewn into the infant’s heart, which reroutes blood from the venae cavae to the left atrium, then to the left ventricle, which then pumps deoxygenated blood to the lungs. Once the oxygenated blood returns from the lungs, it is pumped by the right ventricle to the systemic circulation.
