Successful two-stage correction of transposition of the great vessels.

The Mustard cardiovascular procedure, which  "allows total correction of transposition of the great vessels. The procedure employs a baffle to redirect caval blood flow to the left atrium which then pumps blood to the left ventricle which then pumps the deoxygenated blood to the lungs. In a normal heart, de-oxygenated blood is pumped into the lungs via the right ventricle. Then it is distributed throughout the body via the left ventricle. In the Mustard procedure, blood is pumped to the lungs via the left ventricle and disseminated throughout the body via the right ventricle" (Wikipedia article on Mustard procedure, accessed 2-2020).
