Thanks to evolving technologies, treatments for diseases of the heart, arteries, and veins could soon see improvements by way of the laser.HANK HOGAN, CONTRIBUTING EDITORFor some cardiovascular patients, laser-based procedures have become the best, and perhaps only, option to relieve pain and restore function associated with many diseases of the heart, arteries, and veins. New wavelengths, more rugged setups, lower-cost systems, and other advancements are being combined with minimally invasive techniques. Such combinations often promise improved patient outcomes and lower overall cost of therapy. One new laser approach for blood-flow-related ailments involves the treatment of peripheral artery disease (PAD), a condition in which plaque builds up within...Read full articleRelated content from Photonics MediaARTICLESLaser Technology Enhances and Expands the Medical ToolkitMedical lasers have been used for decades in surgical contexts.
