[Transcutaneous transcatheter use of laser recanalization of coronary arteries in patients with ischemic heart disease].

The paper discusses the potential possibility and effectiveness of X-ray endovascular laser recanalization (ELR) of the coronary arteries in order to treat coronary atherosclerosis in patients with coronary heart disease. The intervention was performed in 4 patients (into the anterior interventricular artery in 3 and into the right coronary artery in 1). In 3 of 4 cases, X-ray ELR proved to be successful, in one case the intervention failed due to technological reasons. Recanalization of a completely occluded segment of the coronary artery with a residual stenosis of no more than 40% was observed in two cases. Laser recanalization of profound local coronary stenosis was made in the mid-third of the vessel in one case. It can be stated that X-ray ELR of the coronary artery may extend the scope of X-ray surgical therapeutical tools of the treatment of coronary atherosclerosis. At the same time, accumulation of clinical experience and further improvement of laser and laser catheter engineering are essential in defining the value and possible scope for the application of this method.
