[A first experience with and possibilities of roentgenovascular dilatation of stenosis of the coronary arteries].

First experience with roentgeno-endovascular dilatation of a coronary artery is described, and reported data are reviewed. Roentgeno-endovascular dilatation is indicated for patients with a single 10-12-mm-long coronary arterial stenosis of hemodynamic significance, localized proximally in the left coronary arterial network, or along the trunk of the right coronary artery, where left ventricular function remains intact and the history of the disease is rather short (not more than 1.5 years).
