In human anatomy, the left and right posterior communicating arteries are small [1]: 471 arteries at the base of the brain that form part of the circle of Willis. Anteriorly, it unites with the internal carotid artery (ICA) (prior to the terminal bifurcation of the ICA into the anterior cerebral artery and middle cerebral artery ); posteriorly ...
In a stage 1 Norwood procedure for hypoplastic right heart, the main pulmonary artery is separated from the left and right portions of the pulmonary artery and joined with the upper portion of the aorta. The proximal pulmonary artery is connected to the aortic arch, while the narrowed segment of the pulmonary trunk is repaired.
Defects in infundibulum development can result in a heart condition known as tetralogy of Fallot. A tendinous band extends upward from the right atrioventricular fibrous ring and connects the posterior surface of the infundibulum to the aorta. The infundibulum is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk.

[ 4 ] When the heart has to pump against increased resistance, or afterload , as in the case of a ventricular obstruction, it compensates by growing in size.
The right and left posterior cerebral arteries arise from the basilar artery, which is formed by the left and right vertebral arteries. The vertebral arteries arise from the subclavian arteries. The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side. All ...
