[Complex angioplasty. (I). Single dilatation versus multiple dilatation in patients with multi-vessel coronary disease].
Coronary angioplasty was successfully performed in 658/752 multivessel disease patients. One lesion was attempted in 338 patients (45%); two or more in 414 patients (55%). Complications occurred in 39 patients (5.2%): 19 (2.5%) had a transmural infarction, 26 (3.5%) urgent surgery, and 14 (1.9%) died. Recurrence occurred in 233/658 (35%) patients with 162/171 (94.7%) having a successful second angioplasty. Clinical improvement (follow-up: 31 months) remained in 81% of successful patients. Survival was not affected by the number of dilations performed but was adversely affected by the presence of prior surgery and ventricular dysfunction. Angioplasty can be an effective treatment without the need to dilate all vessels.
