[A first experience with and possibilities of roentgenovascular dilatation of stenosis of the coronary arteries]. / Pervyi opyt i vozmozhnosti rentgenoéndovaskuliarnoi dilatatsii stenozov koronarnykh arterii.

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). Contraindications for roentgeno-endovascular dilatation currently include local coronary arterial stenosis localized at a major branching-off junction; coronary arterial stenosis of more than 15 mm in length; multiple coronary arterial stenoses; stenosis affecting several major arteries; calcification of coronary arterial wall; left ventricular scarry changes in myocardial area of expected revascularization; absence of indications for aorto-coronary shunting.
