Light-induced vasodilation of coronary arteries and its possible clinical implication

Annals of Thoracic Surgery, 04/06/2012

Vessels exposed to either light source showed a remarkable as well as comparable photorelaxation at definite energy densities. This effect is mediated by an intracellular nitric oxide–dependent mechanism. As LED sources are of small size, simple, and inexpensive build–up, they may be used during routine coronary artery bypass surgery to ease suturing of anastomosis by target vessel vasodilation.
