Functional state of myocardium after transmyocardial revascularization with Nd:YAG laser

Abstract

Providing a better perfusion of the myocardiuln, translnyocardial revascularization with an Nd:YAG laser improves cardiac function and general condition of patients with ischemic heart disease.

Nanosecond, high‐intensity pulsed laser ablation of myocardium tissue at the ultraviolet, visible, and near‐infrared wavelengths: In‐vitro study

“…As a laser source for this treatment, it is a common practice to use 10.6-mm CO 2 lasers [2][3][4][5], but recently, 2.1-mm Ho:YAG lasers [6][7][8] and 308-nm XeCl excimer lasers [9] have received more attention because their laser beams can be delivered through optical fibers, and therefore the treatment can be accomplished percutaneously. In addition, many other types of lasers such as 2.9-mm Er:YAG lasers [8,10], 1.06-mm Nd:YAG lasers [11], 355-nm frequency-tripled Nd:YAG lasers [12], etc., are currently investigated for being applied to TMLR. For these lasers, not only the wavelength but also the temporal characteristics (pulse width, repetition rate, etc.)…”
