[Mechanical dilatation of coronary artery obstructions (transluminal angioplasty) (author's transl)].

29 procedures of transluminal angioplasty were performed in 25 patients with 26 coronary artery stenoses. Of 18 stenoses passed with the dilatation catheter 14 could be successfully dilated (dilatation of stenoses of greater than or equal to 30%). Localization of stenoses was: left main (3), left anterior descendens (10), left circumflex (2), right coronary artery (10), and aortocoronary bypass (1). Long-term follow up over 2 to 19 months (mean 7 months) showed favourable results in 11 patients, while in 3 restenosis occurred.
