Ligament of Marshall
From Wikipedia, the free encyclopedia

The Ligament of Marshall (LoM) is a complex of muscle bundles, blood vessels, adipose tissue, fibrous structure, ganglia, and nerves between the left atrial appendage and the left superior pulmonary vein.[1][2] The LoM consists of the Vein of Marshall (VoM), a band of muscle called to Marshall Bundle (MB), and the epicardial ganglionated plexi.[1]
Ligament is fibrous connective tissue between bones, so "ligament" in "Ligament of Marshall" is a misnomer.

Atrial fibrillation
Pulmonary vein isolation has been the mainstay of atrial fibrillation reduction, but in many cases there are other sources of arrhythmia, including the LoM.[1][3] Use of ethanol through the VoM has been shown to be an effective way to reduce atrial fibrillation.[4]
Discovery
The LoM was discovered in 1850 by British surgeon John Marshall, which was later named in his honor.[1]
